BNSF RAILWAY COMPANY and SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)



1. Accounting Policies and Interim Results

The Consolidated Financial Statements should be read in conjunction with BNSF Railway Companys Annual Report on Form 10-K for the year ended
December 31, 2005, including the financial statements and notes thereto. The Consolidated Financial Statements include the accounts of BNSF Railway Company and its majority-owned subsidiaries, all of which are separate legal entities
(collectively, BNSF Railway or Company). BNSF Railway is a wholly-owned subsidiary of Burlington Northern Santa Fe Corporation (BNSF), and is the principal operating subsidiary of BNSF. All significant intercompany accounts and transactions have
been eliminated.

The results of operations for any interim period are not necessarily indicative of the results of operations to be
expected for the entire year. In the opinion of management, the unaudited financial statements reflect all adjustments (consisting of only normal recurring adjustments except as disclosed) necessary for a fair statement of BNSF Railways
consolidated financial position as of June 30, 2006, and the results of operations for the three and six month periods ended June 30, 2006 and 2005.

Certain comparative prior period amounts in the Consolidated Financial Statements have been reclassified to conform to the current period presentation. These reclassifications had no effect on previously reported
operating income or net income.

Stock-Based Compensation

Under various stock incentive plans, BNSF has granted options to BNSF Railway employees to purchase BNSF common stock at a price not less than fair market value at the date of grant. Certain employees of the Company
also participate in BNSFs other long-term incentive plans including, among other things, restricted stock and a discounted stock purchase program. The Company adopted Statement of Financial Accounting Standards (SFAS) No. 123R,
Share-Based Payment,on January 1, 2006. This statement requires BNSF Railway to recognize the cost of employee services received in exchange for BNSFs equity instruments. Under SFAS No. 123R, BNSF Railway is required to
record compensation expense over an awards vesting period based on the awards fair value at the date of grant. BNSF Railway has elected to adopt SFAS No. 123R on a modified prospective basis; accordingly, the financial statements
for periods prior to January 1, 2006, will not include compensation cost calculated under the fair value method. Additionally, in conjunction with the adoption of SFAS No. 123R, the Company recorded a favorable cumulative adjustment for
estimated forfeitures of $3 million, which, due to its immateriality, was included as a reduction to compensation expense in the first quarter of 2006.

Prior to January 1, 2006, the Company applied Accounting Principles Board Opinion 25, Accounting for Stock Issued to Employees, and, therefore, recorded the intrinsic value of stock-based compensation as
expense. The following table illustrates the effect on net income and earnings per share if the Company had applied the fair value recognition provisions of SFAS No. 123, Accounting for Stock-Based Compensation, to stock-based employee
compensation (in millions) prior to January 1, 2006:

2. Hedging Activities

The Company uses derivatives to hedge against increases in diesel fuel prices and interest rates as well as to convert a portion of its fixed-rate long-term debt to floating-rate debt. The Company formally documents
the relationship between the hedging instrument and the hedged item, as well as the risk management objective and strategy for the use of the hedging instrument. This documentation includes linking the derivatives that are designated as fair value
or cash flow hedges to specific assets or liabilities on the balance sheets, commitments or forecasted transactions. The Company assesses at the time a derivative contract is entered into, and at least quarterly thereafter, whether the derivative
item is effective in offsetting the changes in fair value or cash flows. Any change in fair value resulting from ineffectiveness, as defined by SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, as amended, is
recognized in current period earnings. For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the derivative instrument is recorded in accumulated other comprehensive income
(AOCI) as a separate component of stockholders equity and reclassified into earnings in the period during which the hedge transaction affects earnings.

BNSF Railway monitors its hedging positions and credit ratings of its counterparties and does not anticipate losses due to counterparty nonperformance.

Fuel

Fuel costs represented 23 percent and 18 percent of total operating expenses during the
six month periods ended June 30, 2006 and 2005, respectively. Due to the significance of diesel fuel expenses to the operations of BNSF Railway and the historical volatility of fuel prices, the Company has entered into hedges to partially
mitigate the risk of fluctuations in the price of its diesel fuel purchases. The fuel hedges include the use of derivatives that are accounted for as cash flow hedges. The hedging is intended to protect the Companys operating margins and
overall profitability from adverse fuel price changes by entering into fuel-hedge instruments based on managements evaluation of current and expected diesel fuel price trends. However, to the extent the Company hedges portions of its fuel
purchases, it may not realize the impact of decreases in fuel prices. Conversely, to the extent the Company does not hedge portions of its fuel purchases, it may be adversely affected by increases in fuel prices. Based on fuel consumption during the
second quarter of 2006 and excluding the impact of the hedges, each one-cent increase in the price of fuel would result in approximately $15 million of additional fuel expense on an annual basis.

Total Fuel-Hedging Activities

As of June 30, 2006, BNSF Railways total fuel hedging positions covered 18 percent and 3 percent of estimated fuel purchases for the remainder of 2006 and 2007, respectively. Hedge positions are closely monitored to ensure that
they will not exceed actual fuel requirements in any period.

The amounts recorded in the Consolidated Statements of Income for fuel-hedge
transactions were as follows (in millions):

BNSF Railway measures the fair value of hedges from data provided by various external
counterparties. To value a swap, the Company uses the forward commodity price for the period hedged. The fair values of costless collars are calculated and provided by the corresponding counterparties.

NYMEX #2 Heating Oil Hedges

As of June 30, 2006, BNSF Railway had entered into fuel swaps and costless collar agreements utilizing New York Mercantile Exchange (NYMEX) #2 heating oil (HO). The hedge prices do not include taxes, transportation costs, certain other
fuel handling costs and any differences which may occur between the prices of HO and the purchase price of BNSF Railways diesel fuel. Over the twelve months ended June 30, 2006, the sum of all such costs averaged approximately 19 cents
per gallon.

During the first half of 2006, the Company converted approximately 129 million gallons of West Texas Intermediate (WTI)
collars into HO swaps at an average price of approximately $0.97 per gallon.

The following tables provide fuel-hedge data based on the
quarter being hedged for all HO fuel hedges outstanding as of June 30, 2006. There are no HO hedge positions beyond the first quarter of 2007.

West Texas Intermediate Crude Oil Hedges

In addition, BNSF Railway enters into fuel swap and costless collar agreements utilizing WTI crude oil. The hedge prices do not include taxes,
transportation costs, certain other fuel handling costs, and any differences which may occur between the prices of WTI and the purchase price of BNSF Railways diesel fuel, including refining costs. Over the twelve months ended June 30,
2006, the sum of all such costs averaged approximately 50 cents per gallon.

No additional WTI hedges were entered into during the first
six months of 2006. However, the Company converted approximately 129 million gallons of WTI collars into HO swaps as discussed in the NYMEX #2 Heating Oil Hedges section.

The following tables provide fuel-hedge data based on the quarter being hedged for all WTI fuel hedges outstanding as of June 30, 2006. There are no
WTI positions beyond the first quarter of 2007.

NYMEX #2 Heating Oil Refining Spread Hedges

During the six months ended June 30, 2006, the Company entered into fuel swap agreements utilizing the HO refining spread (HO-WTI) to hedge the
equivalent of approximately 66 million gallons of fuel with an average swap price of $10.20 per barrel. HO-WTI is the difference in price between HO and WTI; therefore, a HO-WTI swap in combination with a WTI swap is equivalent to a HO swap.

The following table provides fuel hedge data for all HO-WTI fuel hedges outstanding as of June 30, 2006. There are no HO-WTI swaps
beyond the third quarter of 2006.

3. Accounts Receivable, Net

BNSF Railway transfers a portion of its accounts receivable to Santa Fe Receivables Corporation (SFRC), a special purpose subsidiary. SFRC transfers an
undivided interest in such receivables, with limited exceptions, to a master trust and causes the trust to issue an undivided interest in the receivables to investors (the A/R sales program). The undivided interests in the master trust may be in the
form of certificates or purchased interests.

The Companys total capacity to sell undivided interests to investors under the A/R
sales program was $700 million at June 30, 2006, which was comprised of two $350 million, 364-day accounts receivable facilities that mature in October 2006. The Company expects to renew the facilities upon their expiration in October.
Outstanding undivided interests held by investors under the A/R sales program were $500 million and $300 million at June 30, 2006, and December 31, 2005, respectively. These receivables are excluded from accounts receivable by BNSF Railway
in connection with the sale of undivided interests under the A/R sales program. The undivided interests were supported by $1,104 million and $1,008 million of receivables transferred by SFRC to the master trust at June 30, 2006, and
December 31, 2005, respectively. When SFRC transfers these receivables to the master trust, it retains an undivided interest in the receivables sold. This retained interest is included in accounts receivable in the Companys financial
statements. SFRCs retained interest in these receivables of $604 million and $708 million at June 30, 2006, and December 31, 2005, respectively, less an allowance for uncollectible accounts, reflected the total accounts receivable
transferred by SFRC to the master trust less $500 million and $300 million at June 30, 2006, and December 31, 2005, respectively, of outstanding undivided interests held by investors. Due to a relatively short collection cycle, the fair
value of the undivided interest transferred to investors in the A/R sales program approximated book value, and there was no gain or loss from the transaction.

The Company retains the collection responsibility with respect to the accounts receivable. Proceeds from collections reinvested in the A/R sales program were approximately $7.6 billion and $6.4 billion for the six
months ended June 30, 2006 and 2005, respectively. No servicing asset or liability has been recorded because the fees the Company receives for servicing the receivables approximate the related costs. SFRCs costs of the sale of receivables
are included in other expense, net and were $10 million and $6 million for the six months ended June 30, 2006 and 2005, respectively. These costs fluctuate monthly with changes in prevailing interest rates and were based on weighted average
interest rates of 4.8 percent and 2.9 percent in the six months ended June 30, 2006 and 2005, respectively. These costs include interest, discounts associated with transferring the receivables under the A/R sales program to SFRC, program fees
paid to banks, incidental commercial paper issuing costs, and fees for unused commitment availability.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)  (Continued)



The amount of accounts receivable transferred by BNSF Railway to SFRC fluctuates based upon the
availability of receivables and is directly affected by changing business volumes and credit risks, including dilution and delinquencies. BNSF Railway has historically experienced very low levels of default or dilution. If dilution or delinquency
percentages were to increase by one percentage point, there would be no impact to the amount of receivables BNSF Railway could sell.

Receivables funded under the A/R sales program may not include amounts over 90 days past due or concentrations over certain limits with any one customer and certain other receivables. At June 30, 2006, and December 31, 2005, $31
million and $36 million, respectively, of accounts receivable were greater than 90 days old. The Company maintains an allowance for bill adjustments and uncollectible accounts based upon the expected collectibility of accounts receivable, including
receivables transferred to the master trust. Credit losses are based on specific identification of uncollectible accounts and application of historical collection percentages by aging category. At June 30, 2006, and December 31, 2005, $40
million and $45 million, respectively, of such allowances had been recorded, of which $36 million and $42 million, respectively, had been recorded as a reduction to accounts receivable, net. Additionally, at June 30, 2006, and December 31,
2005, approximately $4 million and $3 million, respectively, had been recorded as an allowance for bill adjustments and uncollectible accounts in accounts payable and other current liabilities because they relate to the outstanding undivided
interests held by investors. During the six months ended June 30, 2006 and 2005, $4 million of accounts receivable were written off.

The investors in the master trust have no recourse to BNSF Railways other assets except for customary warranty and indemnity claims. Creditors of BNSF Railway have no recourse to the assets of the master trust or SFRC unless and until
all claims of their respective creditors have been paid. The A/R sales program includes provisions that, if triggered, allow the investors participating in this program, at their option, to cancel the program. At June 30, 2006, BNSF Railway was
in compliance with these provisions.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)  (Continued)



Kinder Morgan Energy Partners, L.P.

Santa Fe Pacific Pipelines, Inc. (SFPP), an indirect, wholly owned subsidiary of BNSF Railway, has a guarantee in connection with its remaining special
limited partnership interest in SFPP, L.P., a subsidiary of Kinder Morgan Energy Partners, L.P. to be paid only upon default by the partnership. All obligations with respect to the guarantee will cease upon termination of ownership rights, which
would occur upon a put notice issued by BNSF Railway or the exercise of the call rights by the general partners of SFPP, L.P.

Kansas
City Terminal Intermodal Transportation Corporation

BNSF Railway and another major railroad jointly and severally guarantee $62
million of debt of Kansas City Terminal Intermodal Transportation Corporation, the proceeds of which were used to finance construction of a double track grade separation bridge in Kansas City, Missouri, which is operated and used by Kansas City
Terminal Railway Company (KCTRC). BNSF Railway has a 25 percent ownership in KCTRC, accounts for its interest using the equity method of accounting, and will be required to fund a portion of the remaining obligation upon default by the original
debtor.

Westside Intermodal Transportation Corporation and The Unified Government of Wyandotte County/Kansas City, Kansas

BNSF Railway has outstanding guarantees of $55 million of debt, the proceeds of which were used to finance construction of a bridge
that connects BNSF Railways Argentine Yard in Kansas City, Kansas, with the KCTRC mainline tracks in Kansas City, Missouri. The bridge is operated by KCTRC, and payments related to BNSF Railways guarantee of this obligation will only be
called for upon default by the original debtor.

Residual value guarantees (RVG)

In the normal course of business, the Company enters into leases in which it guarantees the residual value of certain leased equipment. Some of these
leases have renewal or purchase options, or both, that the Company may exercise at the end of the lease term. If the Company elects not to exercise these options, it may be required to pay the lessor an amount not exceeding the RVG. The amount of
any payment is contingent upon the actual residual value of the leased equipment. Some of these leases also require the lessor to pay the Company any surplus if the actual residual value of the leased equipment is over the RVG. These guarantees will
expire between 2006 and 2011.

The maximum future payments, as disclosed in the Guarantees table above, represent the undiscounted maximum
amount that BNSF Railway could be required to pay in the event the Company did not exercise its renewal option and the fair market value of the equipment had significantly declined. BNSF Railway does not anticipate such a large reduction in the fair
market value of the leased equipment. As of June 30, 2006, the Company had recorded a $69 million asset and corresponding liability for the fair value of the RVG.

All other

As of June 30, 2006, BNSF Railway guaranteed $9 million of other debt and
leases. BNSF Railway holds a performance bond and has the option to sub-lease property to recover up to $4 million of the $9 million of guarantees. These guarantees expire between 2006 and 2014.

Other than as discussed above, there is no collateral held by a third party that the Company could obtain and liquidate to recover any amounts paid under
the above guarantees.

Other than as discussed above, none of the guarantees are recorded in the Consolidated Financial Statements of the
Company. The Company does not expect performance under these guarantees to have a material effect on the Company in the foreseeable future.

Indemnities

In the ordinary course of business, BNSF Railway enters into agreements with third parties that include indemnification clauses. In general, these clauses
are customary for the types of agreements in which they are included. At times, these clauses may involve indemnification for the acts of the Company, its employees and agents, indemnification for another partys acts, indemnification for
future events, indemnification based upon a certain standard of performance, indemnification for liabilities arising out of the Companys use of leased equipment or other property, or other types of indemnification. Due to the uncertainty of
whether events which would trigger the indemnification obligations would ever occur, the Company does not believe that these indemnity agreements will have a material adverse effect on the Companys results of operations, financial position or
liquidity. Additionally, the Company believes that, due to lack of historical payment experience, the fair value of indemnities cannot be estimated with any amount of certainty and that the fair value of any such amount would be immaterial to the
financial statements. Accordingly, no fair value liability related to indemnities has been recorded in the financial statements.

5. Commitments
and Contingencies

Personal Injury

Personal injury claims, including asbestos claims and employee work-related injuries and third-party injuries (collectively, other personal injury), are a significant expense for the railroad industry. Personal injury claims by BNSF Railway
employees are subject to the provisions of the Federal Employers Liability Act (FELA) rather than state workers compensation laws. FELAs system of requiring the finding of fault, coupled with unscheduled awards and reliance on the
jury system, contributed to increased expenses in past years. Other proceedings include claims by non-employees for punitive as well as compensatory damages. A few proceedings purport to be class actions. The variability present in settling these
claims, including non-employee personal injury and matters in which punitive damages are alleged, could result in increased expenses in future years. BNSF Railway has implemented a number of safety programs designed to reduce the number of personal
injuries as well as the associated claims and personal injury expense.

BNSF Railway records a liability for personal injury claims when
the expected loss is both probable and reasonably estimable. The liability and ultimate expense projections are estimated using standard actuarial methodologies. Liabilities recorded for unasserted personal injury claims are based on information
currently available. Due to the inherent uncertainty involved in projecting future events such as the number of claims filed each year, developments in judicial and legislative standards, and the average costs to settle projected claims, actual
costs may differ from amounts recorded. BNSF Railway has obtained insurance coverage for certain claims, as discussed under the heading BNSF Insurance Company.

Asbestos

The Company is party
to a number of personal injury claims by employees and non-employees who may have been exposed to asbestos. The heaviest exposure for BNSF Railway employees was due to work conducted in and around the use of steam locomotive engines that were phased
out between the years of 1950 and 1967. However, other types of exposures, including exposure from locomotive component parts and building materials, continued after 1967, until they were substantially eliminated by 1985.

Annually, BNSF Railway engages a third party with extensive experience in performing asbestos studies to assist in assessing its unasserted liability
exposure. The objective of the assessment is to determine the number of estimated unasserted asbestos claims and the estimated average cost per claim by estimating its exposed population, which is used to derive the estimated number of unasserted
claims that will likely require payment by the Company. The estimated average cost per claim is determined utilizing recent actual average cost per claim data.

During the third quarter of 2005, the Company obtained an update of the original September 2004 study, which indicated that the original study continued to represent a reasonable estimate of BNSF Railways future
asbestos exposure. Therefore, management recorded no additional expense as a result of this update. Although the Company plans to update the study again in the third quarter of 2006, BNSF Railway monitors actual experience against the number of
forecasted claims and expected claim payments and will record adjustments to the Companys estimates when necessary.

Of the June 30, 2006 obligation, $256 million was related to unasserted claims while $62
million was related to asserted claims. At June 30, 2006, $21 million was included in current liabilities. The recorded liability was not discounted. In addition, defense and processing costs, which are recorded on an as-reported basis, were
not included in the recorded liability. The Company is presently self-insured for asbestos-related claims.

Based on BNSF Railways estimate of the potentially exposed employees and related mortality
assumptions, it is anticipated that unasserted claims will continue to be filed through the year 2050. The Company recorded an amount for the full estimated filing period through 2050 because it had a relatively finite exposed population (former and
current employees hired prior to 1985), which it was able to identify and reasonably estimate and about which it had obtained reliable demographic data (including age, hire date and occupation) derived from industry or BNSF Railway specific data
that was the basis for the study. BNSF Railway projects that approximately 50, 70 and 90 percent of the future unasserted asbestos claims will be incurred within the next 10, 15 and 25 years, respectively.

Because of the uncertainty surrounding the factors used in the study, it is reasonably possible that future costs to settle asbestos claims may range
from approximately $225 million to $425 million. However, BNSF Railway believes that the $318 million recorded is the best estimate of the Companys future obligation for the settlement of asbestos claims.

The amounts recorded by BNSF Railway for the asbestos-related liability were based upon currently known facts. Future events, such as the number of new
claims to be filed each year, the average cost of disposing of claims, as well as the numerous uncertainties surrounding asbestos litigation in the United States, could cause the actual costs to be higher or lower than projected.

While the final outcome of asbestos-related matters cannot be predicted with certainty, considering among other things the meritorious legal defenses
available and liabilities that have been recorded, it is the opinion of BNSF Railway that none of these items, when finally resolved, will have a material adverse effect on the Companys financial position or liquidity.

However, the occurrence of a number of these items in the same period could have a material adverse effect on the results of operations in a particular
quarter or fiscal year.

Other Personal Injury

BNSF Railway uses a third-party actuary to assist the Company in estimating its other personal injury liability claims and expense. These estimates are based on the covered population, activity levels and trends in
frequency, and the costs of covered injuries. These actuarial estimates include unasserted claims except for certain repetitive stress and other occupational trauma claims that result from prolonged repeated events or exposure. Such claims are
estimated on an as-reported basis because, while the Company has concluded that a probable loss has occurred, it cannot estimate the range of reasonably possible loss due to other contributing causes of such injuries and the fact that continued
exposure is required for the potential injury to manifest itself as a claim. The Company believes that the low end of the range of reasonably possible loss, as that term is used in Financial Accounting Standards Board (FASB) Interpretation
No. 14 (FIN 14), Reasonable Estimation of the Amount of Loss, is immaterial for these other occupational trauma claims.

BNSF
Railway obtains quarterly actuarial updates for other personal injury liabilities and monitors actual experience against the number of forecasted claims to be received, the forecasted number of claims closing with payment and expected claims
payments. Adjustments to the Companys estimates are recorded quarterly as necessary or more frequently as new events or revised estimates develop.

The following table summarizes the activity in the Companys accrued obligations for other personal injury matters (in millions):

At June 30, 2006, $164 million was included in current liabilities. BNSF Railways
liabilities for other personal injury claims are undiscounted. In addition, defense and processing costs, which are recorded on an as-reported basis, were not included in the recorded liability. The Company is substantially self-insured for other
personal injury claims.

Because of the uncertainty surrounding the ultimate outcome of other personal injury claims, it is
reasonably possible that future costs to settle other personal injury claims may range from approximately $375 million to $525 million. However, BNSF Railway believes that the $426 million recorded is the best estimate of the Companys future
obligation for the settlement of other personal injury claims.

BNSF Insurance Company

Burlington Northern
Santa Fe Insurance Company, Ltd. (BNSF IC), a wholly owned subsidiary of BNSF, provides insurance coverage for FELA claims; certain risks incurred after April 1, 1998; railroad protective and force account insurance claims incurred after
January 1, 2002; and certain other claims which are subject to reinsurance. During the six months ended June 30, 2006 and 2005, BNSF Railway paid $142 million and $140 million, respectively, in premiums to BNSF IC for such coverage and
recognized $71 and $70 million, respectively, in expense related to those premiums. At June 30, 2006, unamortized premiums of $71 million remain on the Consolidated Balance Sheet. During the first six months of 2006 and 2005, BNSF IC made claim
payments to BNSF Railway totaling $66 million and $56 million, respectively, for settlement of covered claims.

Environmental

The Companys operations, as well as those of its competitors, are subject to extensive federal, state and local environmental regulation. BNSF
Railways operating procedures include practices to protect the environment from the risks inherent in railroad operations, which frequently involve transporting chemicals and other hazardous materials. Additionally, many of BNSF Railways
land holdings are and have been used for industrial or transportation-related purposes or leased to commercial or industrial companies whose activities may have resulted in discharges onto the property. As a result, BNSF Railway is subject to
environmental cleanup and enforcement actions. In particular, the Federal Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA), also known as the Superfund law, as well as similar state laws, generally impose joint
and several liability for cleanup and enforcement costs on current and former owners and operators of a site without regard to fault or the legality of the original conduct. BNSF Railway has been notified that it is a potentially responsible party
(PRP) for study and cleanup costs at Superfund sites for which investigation and remediation payments are or will be made or are yet to be determined (the Superfund sites) and, in many instances, is one of several PRPs. In addition, BNSF Railway may
be considered a PRP under certain other laws. Accordingly, under CERCLA and other federal and state statutes, BNSF Railway may be held jointly and severally liable for all environmental costs associated with a particular site. If there are other
PRPs, BNSF Railway generally participates in the cleanup of these sites through cost-sharing agreements with terms that vary from site to site. Costs are typically allocated based on such factors as relative volumetric contribution of material, the
amount of time the site was owned or operated, and/or the portion of the total site owned or operated by each PRP.

Liabilities for
environmental cleanup costs are recorded when BNSF Railways liability for environmental cleanup is probable and reasonably estimable. Subsequent adjustments to initial estimates are recorded as necessary based upon additional information
developed in subsequent periods. Environmental costs include initial site surveys and environmental studies as well as costs for remediation of sites determined to be contaminated.

BNSF Railway engages a third-party actuary to assist the Company in estimating the ultimate cost of cleanup efforts at its known environmental sites. The
actuary utilizes BNSF Railways historical payment patterns, its current estimated percentage to closure ratios, and the actuarys proprietary benchmark patterns developed from data accumulated from public sources and work performed by it
for other clients, including the EPA and other governmental agencies. These factors incorporate experience gained from cleanup efforts at other similar sites into the estimates for which remediation and restoration efforts are still in progress.

Based on the work performed by the third party actuary, during the third quarter of 2005, management
recorded additional expense of approximately $12 million. The Company plans to update the study again in the third quarter of 2006. However, on a quarterly basis, BNSF Railway monitors actual experience against the forecasted remediation and related
payments made on existing sites and conducts ongoing environmental contingency analyses, which consider a combination of factors including independent consulting reports, site visits, legal reviews and analysis of the likelihood of participation in,
and the ability to pay for, cleanup of other PRPs. Adjustments to the Companys estimates will continue to be recorded when necessary based on developments in subsequent periods.

The study does not include (i) contaminated sites of which the Company is not aware, or (ii) additional amounts for third-party claims, which
arise out of contaminants allegedly migrating from BNSF Railway property, due to a limited number of sites. BNSF Railway continues to estimate third-party claims on a site by site basis when the liability for such claims is probable and reasonably
estimable. Environmental accruals include amounts for newly identified sites or contaminants, third-party claims, and legal fees incurred for defense of third-party claims and recovery efforts. BNSF Railways recorded liability for third-party
claims as of June 30, 2006, is approximately $16 million.

BNSF Railway is involved in a number of administrative and judicial
proceedings and other mandatory cleanup efforts for 374 sites, including Superfund sites, at which it is participating in the study or cleanup, or both, of alleged environmental contamination.

The following table summarizes the activity in the Companys accrued obligations for environmental matters (in millions):

At June 30, 2006, $50 million was included in current liabilities. BNSF Railways
environmental liabilities are not discounted. BNSF Railway anticipates that the majority of the accrued costs at June 30, 2006, will be paid over the next ten years, and no individual site is considered to be material.

The following table summarizes the environmental sites:

Liabilities recorded for environmental costs represent BNSF Railways best estimate of its
probable future obligation for the remediation and settlement of these sites and include both asserted and unasserted claims. Unasserted claims are not a material component of the liability. Although recorded liabilities include BNSF Railways
best estimate of all probable costs, without reduction for anticipated recoveries from third parties, BNSF Railways total cleanup costs at these sites cannot be predicted with certainty due to various factors such as the extent of corrective
actions that may be required, evolving environmental laws and regulations, advances in environmental technology, the extent of other parties participation in cleanup efforts, developments in ongoing environmental analyses related to sites
determined to be contaminated, and developments in environmental surveys and studies of contaminated sites.

Because of the uncertainty
surrounding these factors, it is reasonably possible that future costs for environmental liabilities may range from approximately $300 million to $600 million. However, BNSF Railway believes that the $335 million recorded is the best estimate of the
Companys future obligation for environmental costs.

While the final outcome of these environmental matters cannot be predicted with
certainty, it is the opinion of BNSF Railway that none of these items, when finally resolved, will have a material adverse effect on the Companys financial position or liquidity. However, the occurrence of a number of these items in the same
period could have a material adverse effect on the results of operations in a particular quarter or fiscal year.

Other Claims and Litigation

In addition to asbestos, other personal injury, and environmental matters discussed above, BNSF Railway and its subsidiaries are
also parties to a number of other legal actions and claims, various governmental proceedings and private civil suits arising in the ordinary course of business, including those related to disputes and complaints involving certain transportation
rates and charges (including complaints seeking refunds of prior charges paid for coal transportation and the prescription of future rates for such movements, and claims relating to service including under contract provisions). Some of the legal
proceedings include claims for punitive as well as compensatory damages, and a few proceedings purport to be class actions. While the final outcome of these matters cannot be predicted with certainty, considering among other things the meritorious
legal defenses available and liabilities that have been recorded along with applicable insurance, it is the opinion of BNSF Railway that none of these items, when finally resolved, will have a material adverse effect on the Companys financial
position or liquidity. However, an unexpected adverse resolution of one or more of these items could have a material adverse effect on the results of operations in a particular quarter or fiscal year.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)  (Continued)



Employee separation liabilities of $120 million were included in the Consolidated Balance Sheet at
June 30, 2006, and principally represent the following: (i) deferred benefits payable upon separation or retirement to certain active conductors, trainmen and locomotive engineers; (ii) employee-related severance costs for the
consolidation of clerical functions, material handlers in mechanical shops and trainmen on reserve boards; and (iii) certain non-union employee severance costs. Employee separation expenses are recorded in materials and other in the
Consolidated Statements of Income. At June 30, 2006, $25 million of the remaining liabilities were included in current liabilities.

Conductors,
Trainmen and Locomotive Engineers

Liabilities related to deferred benefits payable upon separation or retirement to certain active
conductors, trainmen and locomotive engineers were $109 million at June 30, 2006. These costs were primarily incurred in connection with labor agreements reached prior to the consummation of the business combination of BNSFs predecessor
companies, Burlington Northern, Inc. and Santa Fe Pacific Corporation (the Merger) which, among other things, reduced train crew sizes and allowed for more flexible work rules. The remaining costs will be paid between 2006 and approximately 2024.
During the first six months of 2005, the Company updated its estimate and recorded an additional liability of $2 million related to deferred benefits.

Consolidation of Clerical Functions

Liabilities related to the consolidation of clerical functions were $7 million
at June 30, 2006, and primarily provide for separation programs announced in 2003, 2004 and 2005 and severance costs associated with the clerical consolidation plan adopted in 1995 upon the Merger. During 2005, BNSF Railway recorded other
liabilities of approximately $5 million primarily related to a voluntary severance program for certain union employees, $4 million of which was recorded during the first six months of the year. The July 2004 separation program affected approximately
40 employees and resulted in accrued severance costs of approximately $4 million. Reductions related to the July 2004 separation program were substantially completed by December 31, 2004. The July 2003 separation program resulted in accrued
severance costs of approximately $12 million, affected approximately 150 employees and was substantially completed in 2003. The 1995 consolidation plan resulted in the elimination of approximately 1,500 permanent positions and was substantially
completed during 1999. The liability also includes costs related to the reduction of approximately 40 and 140 material handlers in 2001 and 2000, respectively.

Other Employee Separation Costs

Other employee separation cost liabilities were $4 million at June 30, 2006,
and principally relate to certain remaining non-union employee severances resulting from the fourth quarter 2001 workforce reduction and the Merger. These costs will be paid over the next several years based on deferral elections made by the
affected employees. Also included in the other separation cost accrual is an estimate for the remaining payments to be made to other union employees as a result of a relocation program initiated in 2005 for which a $1 million accrual was recorded.
As of June 30, 2006, the remaining liability balance related to this voluntary severance program was insignificant as the program is substantially complete.

8. Stock-Based Compensation

On April 15, 1999, BNSF shareholders approved the BNSF 1999 Stock Incentive Plan and authorized 20 million shares of BNSF common stock to be issued in connection with stock options, restricted stock,
restricted stock units and performance stock. On April 18, 2001, April 17, 2002, April 21, 2004 and April 19, 2006, BNSF shareholders approved the amended BNSF 1999 Stock Incentive Plan, which authorized additional
awards of 9 million, 6 million, 7 million and 11 million shares, respectively, of BNSF common stock to be issued in connection with stock options, restricted stock, restricted stock units and performance stock. Approximately
12 million common shares were available for future grant at June 30, 2006.

Additionally, on April 18, 1996, BNSF
shareholders approved the non-employee directors stock plan and authorized 900,000 shares of BNSF common stock to be issued in connection with this plan. Approximately 500,000 common shares were available for future grant at June 30,
2006.

Stock Options

Under
BNSFs stock plans, options may be granted to directors, officers and salaried employees at the fair market value of BNSFs common stock on the date of grant. Stock option grants generally vest ratably over three years and expire within
ten years after the date of grant. Shares issued upon exercise of options may be issued from treasury shares or from authorized but unissued shares.

The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model. The following assumptions apply to the options granted for the periods presented.

Expected volatilities are based on historical volatility of BNSFs stock, implied
volatilities from traded options on BNSFs stock and other factors. The Company uses historical experience with exercise and post-vesting employment termination behavior to determine the options expected life. The expected life represents
the period of time that options granted are expected to be outstanding. The risk-free rate is based on the U.S. Treasury rate with a maturity date corresponding to the options expected life.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)  (Continued)



Performance-based awards are granted to senior managers within BNSF to encourage ownership in BNSF
and to align managements interest with those of its shareholders. Performance-based awards generally vest over three years and are contingent on the achievement of certain predetermined corporate performance goals (e.g., return on invested
capital (ROIC)) and continued salaried employment. The grant date fair market value of performance-based awards granted during the three and six months ended June 30, 2005 was $49.21.

Additionally, related to the 2006 and 2005 performance-based grant, eligible employees may also earn performance stock that will be granted in 2009 and
2008 contingent upon achievement of higher ROIC goals and continued salaried employment. The Company has committed to a maximum grant of approximately 235,000 and 316,000 shares, respectively.

Certain eligible employees may exchange through the BNSF Incentive Bonus Stock Program (IBSP) the cash payment of their bonus for grants of restricted
stock. The grant date fair market value of IBSP awards granted during the six months ended June 30, 2005 was $47.58. No IBSP awards were granted during the second quarter of 2005. In September 2005, the program was amended so that exchanges of
cash bonus payments for awards of restricted stock were no longer permitted after February 2006.

Certain other salaried employees may
participate in the BNSF Discounted Stock Purchase Program (DSPP) and use their bonus to purchase BNSF common stock at a discount from the market price. These shares immediately vest but are restricted for a three-year period. The grant date fair
market value of DSPP awards granted during the six months ended June 30, 2005 was $46.91. No DSPP awards were granted during the second quarter of 2005.

Shares awarded under each of the plans may not be sold or used as collateral and are generally not transferable by the holder until the shares awarded become free of restrictions. Compensation expense, net of tax,

BNSF with a variable interest rate of 1.0 percent above the monthly average of the daily effective Federal Funds rate. The $73 million decrease in intercompany notes receivable is due to $726 million of repayments from BNSF offset by additional
borrowings of $653 million during the first six months of 2006. The intercompany notes receivable are presented net of the intercompany notes payable discussed above in the Consolidated Balance Sheets. Interest income from intercompany notes

market value at the date of grant. Certain employees of BNSF Railway participate in these plans. In addition, under these plans BNSF has other long-term incentive plans to certain BNSF Railway employees, including, among other things, restricted
stock and a discounted stock purchase program. See Notes 1 and 8 for additional information regarding compensation expense recorded for stock incentive plans.

10. Accounting Pronouncement

In June 2006, the FASB issued FIN 48, Accounting for Uncertainty in Income Taxesan
interpretation of FASB Statement No. 109, Accounting for Income Taxes,which clarifies the accounting for uncertainty in income taxes. FIN 48 prescribes a recognition threshold and measurement attribute for the financial statement recognition
and measurement of a tax position taken or expected to be taken in a tax return. The Interpretation requires that the Company recognize in the financial statements, the impact of a tax position, if that position is more likely than not of being
sustained on audit, based on the technical merits of the position. FIN 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods and disclosure. The provisions of FIN 48 are effective beginning
January 1, 2007 with the cumulative effect of the change in accounting principle recorded as an adjustment to opening retained earnings. The Company is currently evaluating the impact of adopting FIN 48 on the financial statements.

Report of Independent Registered Public Accounting Firm

To the Shareholder and Board of Directors

of BNSF Railway Company:

We have reviewed the accompanying consolidated balance sheet of BNSF Railway Company and its subsidiaries (BNSF Railway or the
Company) as of June 30, 2006, and the related consolidated statements of income for each of the three-month and six-month periods ended June 30, 2006 and 2005, the consolidated statements of cash flows for the six-months ended
June 30, 2006 and 2005 and the consolidated statement of changes in stockholders equity for the six-month period ended June 30, 2006. These interim financial statements are the responsibility of the Companys management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial
information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the
Public Company Accounting Oversight Board, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the accompanying consolidated interim financial statements for them to be in
conformity with accounting principles generally accepted in the United States of America.

We previously audited in accordance with the standards of the
Public Company Accounting Oversight Board (United States), the consolidated balance sheet as of December 31, 2005, and the related consolidated statements of income, of changes in stockholders equity and of cash flows for the year then
ended (not presented herein), and in our report dated February 13, 2006, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated balance sheet
information as of December 31, 2005, is fairly stated in all material respects in relation to the consolidated balance sheet from which it has been derived.

Freight revenues for the first six months of 2006 were $6,959 million, up 17-percent compared with
the same 2005 period. Freight revenues include approximately $775 million in fuel surcharges compared with approximately $390 million in the prior year. This increase was due to a 7-percent increase in cars/units and a 10-percent increase in average
revenue per car/unit.

Consumer Products

Consumer Products revenues of $2,797 million for the first six months of 2006 were $429 million, or 18 percent, greater than the first six months of 2005. The 7-percent increase in cars/units was primarily due to
strong increases in the international and domestic intermodal. Additionally, the increase in average revenue per unit of 10 percent, which was driven primarily by rate increases and increased fuel surcharges, contributed to the overall revenue
growth.

Industrial Products

Industrial Products revenues increased $245 million, or 18 percent, to $1,610 million for the first six months of 2006. The revenue increase was driven by double-digit growth in each of the four business areas. Rate increases along with
increases in fuel surcharges and a mix change from short haul, low revenue per unit to longer haul and higher revenue per unit traffic contributed to a 16-percent increase in average revenue per car.

Coal

Coal revenues of $1,393 million
for the first six months of 2006 increased $204 million, or 17 percent, versus the same period a year ago. The 17-percent increase was driven by a 10-percent increase in volumes driven from significant customer demand and network fluidity. Average
revenue per car increased 7 percent, primarily driven by contractual rate escalations, fuel surcharges and increased length of haul.

Agricultural Products revenues of $1,159 million for the first six months of 2006 were $142 million, or 14 percent, higher than revenues for the first six
months of 2005. This increase was due to an 8-percent increase in average revenue per car, which was predominately driven by higher fuel surcharges associated with higher fuel prices, and a 5-percent unit increase driven largely by strong demand for
corn.

Other Revenues

Other Revenues increased $4 million, or 3 percent, to $124 million for the first six months of 2006 compared with the same period in 2005.

Expenses

Total operating expenses for the first six months of 2006 were $5,412 million, an increase of $703
million, or 15 percent, versus the same 2005 period.

Compensation and benefits

Compensation and benefits expenses for the first half of 2006 of $1,839 million were $144 million, or 8 percent, higher than the same 2005 period. This
increase was primarily related to 7-percent higher unit volumes. Additionally, increased pension and stock option expenses were partially offset by a decrease in incentive compensation expense.

Fuel

Fuel expenses of $1,239 million
for the first six months of 2006 were $386 million, or 45 percent, higher than the first six months of 2005. The increase in fuel expense was due to an increase in the average all-in cost per gallon of diesel fuel, as well as an increase in
consumption driven by higher volumes. The average all-in cost per gallon of diesel fuel increased by 47 cents to $1.70, resulting in a $342 million increase in expense. The increase in the average all-in cost was comprised of an increase in the
average purchase price of 47 cents, or $340 million increase in fuel expenses, and a decrease in the hedge benefit of $2 million (first six months 2006 benefit of $227 million less first six months of 2005 benefit of $229 million). Consumption in
the first six months of 2006 was 730 million gallons compared with 694 million gallons in the same 2005 period, resulting in a $44 million increase in fuel expenses.

Purchased services

Purchased service
expenses of $881 million for the first half of 2006 were $86 million, or 11 percent, higher than the same 2005 period. This increase was primarily due to increases in the following volume-related costs: intermodal ramp costs, locomotive and freight
car contract maintenance expense, haulage payments for contracted transportation over other railroads.

Depreciation and amortization

Depreciation and amortization expenses of $555 million for the first half of 2006 were $24 million, or 5 percent, higher than the same
period in 2005. The increase in depreciation expense was due to ongoing capital expenditures.

Equipment rents

Equipment rents expenses for the first six months of 2006 of $463 million were $32 million, or 7 percent, higher than the first six months of 2005. The
variance represents expense increases for freight car equipment and locomotive leases, which are related to volume increases and higher lease rates.

Materials and other

Materials and other expenses of $435 million for the first six months of 2006 were $31 million, or 8 percent, higher than the first six months of 2005. The increase was primarily due to higher materials and crew
transportation and lodging expense driven largely by volume increases, higher property taxes, relocation costs associated with new hires, and partially offset by a first quarter 2006 gain from a line sale of $22 million to the state of New Mexico.

Interest expense

Interest expense of $60 million for the first six months of 2006 was $8 million, or 12 percent, lower than the first six months of 2005. The decrease was primarily due to lower average debt balances.

Income taxes

The effective tax rate
for the six months ended June 30, 2006 was 37.1 percent compared with 38.0 percent for the prior year period. The decrease in the effective tax rate primarily reflects a favorable impact of income tax adjustments related to prior periods.
