Exhibit 10.16

TRINITY INDUSTRIES LEASING COMPANY  RAILROAD CAR LEASE AGREEMENT

This Agreement, made this 5th day of July, 2002, betweenTrinity Industries Leasing Company, a Delaware
corporation, with its principal office at One Tower Lane, 29th Floor, Oak Brook Terrace, Illinois 60181, (hereinafter called "Lessor") andDakota Ethanol
LLCa South Dakota limited liability corporation, with its principal office at 46269 SD Highway 34, Wentworth, South Dakota 57075-6934 (hereinafter called
"Lessee").

In
consideration of the mutual terms and conditions hereinafter set forth, the parties hereto hereby agree as follows:

ARTICLE 1:LEASE AGREEMENT

Lessor agrees to lease to Lessee, and Lessee agrees to lease from Lessor, the cars shown on each Rider hereto and such additional Riders as may be added from time
to time (each such Rider and together with this Agreement shall be collectively referred to as the Lease") by agreement of the parties and signed by their duly authorized representative (all such cars
being hereinafter referred to as the "cars"). Each Rider shall set forth a brief description of the car or cars covered thereby, including such facts as the number of cars, the AAR or DOT
specifications, rental charges, term throughout which the car or cars shall remain in Lessee's service and such other information as may be desired by both parties. Lessor and Lessee agree that each
Rider hereto shall constitute a separate Lease which incorporates the terms of this Agreement. Each Rider shall be severable from any other cars or riders relating to this Agreement and shall become a
separate lease which is separately transferable for all purposes. It is the intent of all parties to this Agreement to characterize this Agreement as a true lease.

ARTICLE 2:DELIVERY

Except as otherwise provided in each Rider hereto, Lessor agrees to deliver each car to Lessee, freight charges collect, in the yard of the delivering line at the
point specified by the Lessee, and Lessee agrees to accept such delivery. The obligations of the Lessor to deliver the cars shall be excused, and Lessor shall not be liable, for any causes beyond the
reasonable control of Lessor (including, but not limited to, delays caused by fire, labor difficulties, delays of carriers and materials suppliers, governmental authority, late delivery by the
manufacturer of the cars or late delivery by a prior lessee) and, in the event of a delay in such delivery, Lessor shall deliver the cars to Lessee as soon as reasonably possible thereafter.

ARTICLE 3:CONDITION OF CARSACCEPTANCE

All cars delivered under this Lease shall be in satisfactory condition for movement in the normal interchange of rail traffic and shall otherwise comply with the
description and specifications contained in the applicable Rider; but Lessee shall be solely responsible for determining that cars are in proper condition for loading and shipment, except for those
responsibilities which, under applicable law, have been assumed by the railroads. Lessee shall inspect the cars promptly after they are delivered and shall notify Lessor in writing within five days
after delivery of its rejection of any car, and the specific reasons for such rejection. Failure by the Lessee to inspect the cars within five days after delivery, and/or the successful loading of any
car by Lessee, shall constitute acceptance of such car or cars, as the case may be, by Lessee and shall be conclusive evidence of the fit and suitable condition of such car or cars. At Lessor's
request, Lessee shall deliver to Lessor an executed Certificate of Acceptance in the form of Exhibit A with respect to all cars.

If
Lessee rejects any car, Lessor shall have the right to have the rejected car inspected by an inspector acceptable to both Lessor and Lessee. The cost of such inspection will be paid
by Lessor if the cause for rejection is affirmed by the inspector, otherwise such cost will be borne by Lessee. The

---

Lessee shall be deemed to have accepted any car for which the inspector determines that good cause for rejection did not exist. The decision of the inspector shall be final and binding upon the
parties.

Lessee's
acceptance, however affected, shall be deemed effective as of the delivery date and the monthly rentals as hereinafter set forth shall accrue from the delivery date. Such
acceptance shall conclusively establish that such cars conform to the applicable standards set forth in the Rider(s) and the Interchange Rules.

ARTICLE 4:RENTALS

Lessee agrees to pay to Lessor for the use of each car the monthly rental set forth in the Rider applicable to such car from the date such car is delivered to
Lessee until such car is returned to Lessor, as hereinafter provided in Article 18. The rental shall be payable in U.S. Dollars and in advance on or before the first day of each calendar month
(provided, however, that the rental for each car for the month in which it is delivered shall be prorated for the number of days, including the day of delivery, remaining in such month at a daily rate
based upon a 365 day year and shall be payable on or before the first day of the next succeeding month) to Lessor at21038 Network Place, Chicago, Illinois
60673-1210, or at such other address as Lessor may specify by notice to Lessee. Except as set forth in this Lease (including without limitation, the provisions of
Article 11) rental shall be paid without deduction, set-off or counterclaim.

ARTICLE 5:MILEAGE ALLOWANCE

Lessor shall collect all mileage earned by the cars during the lease term and shall credit to the rental of Lessee, such mileage earned by the cars while in the
service of Lessee, as and when received from the railroads according to, and subject to, all rules of the tariffs of the railroads.

ARTICLE 6:TERM

This Lease shall be effective as dated and will expire upon the completion of the leasing arrangement shown on the attached Riders of the last car or cars covered
hereunder. The Lease term, with respect to all cars covered by a particular Rider, shall commence on the average date of delivery of the cars covered by such Rider; and shall terminate as specified in
such Rider, unless sooner terminated in accordance with provisions of this Lease.

ARTICLE 7:USE AND POSSESSION

Throughout the continuance of this Lease so long as Lessee is not in default under this Lease, Lessee shall be entitled to possession of each car from the date
the lease becomes effective as to such car; and shall use such car only in the manner for which it was designed and intended, and so as to subject it only to ordinary wear and tear, and on its own
property or lines in the usual interchange of traffic; provided, however, that Lessee agrees that the cars shall at all times be used: (a) in conformity with all Interchange Rules;
(b) in compliance with the terms and conditions of this Lease; (c) predominantly in the continental limits of the United States, provided however, in no event shall more that forty
percent (40%) of the cars (as determined by mileage records and measured annually on a calendar year basis) be used outside of the contiguous United States at the same time.

In
the event any car is used outside of the continental United States, for any reason whatsoever, Lessee shall assume full responsibility for all costs, taxes, duties or other charges
incidental to such use including costs incurred in returning car to the continental United States.

2

---

ARTICLE 8:EMPTY MILEAGE INDEMNIFICATION

Lessee agrees that it will use its best efforts to so use the cars that their total mileage under load will equal or exceed their mileage empty on each railroad
over which the cars move. Should the empty mileage exceed the loaded mileage, Lessee shall pay to Lessor for such excess at the rate and at the time established by the tariff of the railroad on which
such excess of empty miles has accrued. For the purpose of this paragraph, the railroad mileage reports received by Lessor shall be prima facie evidence of the facts reported therein.

ARTICLE 9:ADDITIONAL CHARGES BY RAILROADS

Lessee agrees to use the cars, upon each railroad over which cars shall move, in accordance with the then prevailing tariffs to which each railroad shall be a
party; and if the operation or movements of any of the cars during the term hereof shall result in any charges being made against Lessor by any such railroad, Lessee shall pay to Lessor the amount of
such charges within the period prescribed by and at the rate and under the conditions of the then prevailing tariffs. Lessee agrees to indemnify Lessor against any such charges, and shall be liable
for any switching, demurrage, track storage, detention or special handling charges imposed on any car during the term hereof.

ARTICLE 10:LESSEE'S RIGHT TO TRANSFER OR SUBLEASE

Lessee shall not transfer, sublease or assign any car or its interests and obligations pursuant to the Lease, nor shall a transfer, sublease or assignment by
operation of the law or otherwise of Lessee's interest in the cars or this Lease be effective against Lessor without Lessor's prior written consent. No transfer, sublease or assignment of the Lease,
or of any car, shall relieve Lessee from any of its obligations to Lessor under this Lease.

Notwithstanding
the foregoing paragraph, Lessee shall have the right to sublease any of the cars for single trips to its customers or suppliers, and to cause each car so subleased to be
boarded or placarded with the name of the sublessee in accordance with the provisions of the demurrage tariffs
lawfully in effect, where the sole purpose of such subleasing is to obtain an exemption from demurrage for said cars so subleased; provided, however, that notwithstanding any such sublease, Lessee
shall continue to remain liable to Lessor for the fulfillment of Lessee's obligations under this Lease; and providing further, that Lessor shall have the right, at any time, to withdraw the privilege
of subleasing hereinabove granted to Lessee.

ARTICLE 11:MAINTENANCE RESPONSIBILITY

Lessor agrees to maintain the cars in good condition and repair according to the Interchange Rules of the Association of American Railroads (AAR). Lessee agrees
to notify Lessor promptly when any car is damaged or in need of repair, and to forward such cars and any other cars subject to this Lease to shops as directed by Lessor for repairs and/or periodic
maintenance and inspections. No repairs to any of the cars shall be made by Lessee without Lessor's prior written consent, except that Lessee shall, at its expense, replace any removable part (dome
covers, hatch covers, outlet caps, etc.) if lost or broken. Replacement or repair by Lessee of any parts, equipment and/or accessories on any of the cars shall be with parts, equipment and/or
accessories that are of like kind and of at least equal quality to those being replaced or repaired, unless otherwise agreed in writing by Lessor.

On
tank cars, Lessee agrees that it will assume the responsibility for the maintenance and replacement of angle valves and check valves and, if such cars are so equipped, thermometer
wells, gauging devices, regulator valves, safety heads and top unloading valves.

On
hopper cars, Lessee will be responsible for inspection and cleaning of the operating mechanisms of the outlets, hatches and special fittings on such cars leased herein. Further, any
damage

3

---

to such outlets, hatches, special fittings or the operating mechanisms will be repaired for the account of the Lessee.

When
a car is placed in a private shop for maintenance or repair, the rental charges shall cease on date of arrival in the shop, except in the case where a car arrives without advance
notice of defects from Lessee, in which case rental charges will cease on communication of such notice of defects to Lessor from Lessee, and shall be reinstated on the date that the car is forwarded
from the shop or on the date that the car is ready to leave, awaiting disposition instructions from Lessee. If any repairs are required as a result of the misuse by or negligence of Lessee or its
consignee, agent or sublessee or while on a railroad that does not subscribe to, or fails to meet its responsibility under the Interchange Rules of the AAR, or while on any private siding or track or
any private or industrial railroad, the rental charges shall continue during the repair period, and Lessee agrees to pay Lessor for the cost of such repairs.

ARTICLE 12:LOSS OR DESTRUCTION

If any of the cars shall be completely destroyed, or if the physical condition of any car shall become such that the car cannot be operated in railroad service,
as determined by the parties, then Lessor may, at its option, cancel this Lease as to such car as of the date on which such event occurred, or may substitute another car within a reasonable period of
time. Lessee shall notify Lessor of the occurrence of any such event within two (2) days of such event. In the event of such substitution, the substituted car shall be held pursuant to all the
terms and conditions of this Lease. Lessee agrees that if a car is lost or destroyed or is in such physical condition that it cannot be operated in railroad service by reason of misuse or negligence
of Lessee or its consignee, agent or sublessee or while on any private siding or track or any private or industrial railroad, Lessee will pay Lessor, in cash, the depreciated value of such car as
determined by Rule #107 of the AAR Interchange Rules within ten (10) days following a request by Lessor for such payment. Lessor and Lessee shall cooperate with and assist each other in any
reasonable manner requested, but without affecting their respective obligations under this Article or Article 22, to establish proper claims against parties responsible for the loss,
destruction of or damage to, the cars.

ARTICLE 13:LOSS OF COMMODITY

Lessor shall not be liable for any loss of, or damage to, commodities, or any part thereof, loaded or shipped in the cars however such loss or damage shall be
caused or shall result. Lessee agrees to assume responsibility for, to indemnify Lessor against, and to save it harmless from any such loss or damage or claim therefor.

ARTICLE 14:DAMAGE TO CAR BY COMMODITY

Lessee shall be liable for damage to any car covered by this Lease, whether or not due to Lessee's negligence, if caused by or as a result of the commodity loaded
therein. Lessee assumes responsibility for such damage to any car, including without limitation, as applicable, to the tank, fittings or appurtenances thereto, including the interior lining for tanks
so equipped. Lessee will use said cars for the transportation and handling of commodities which will not injure the cars.

ARTICLE 15:ALTERATION AND LETTERING

Lessee will preserve the cars in good condition and will not in any way alter the physical structure of the cars without the advance approval, in writing, of the
Lessor. Lessee shall place no lettering or marking of any kind upon the cars without Lessor's prior written consent, provided however, that Lessee may cause said cars to be stenciled, boarded, or
placarded with letters not to exceed two inches

4

---

(2") in height to indicate to whom the cars are leased and with commodity stencils per AAR or DOT specifications.

ARTICLE 16:LININGS AND COATINGS

The application, maintenance and removal of interior protective linings and coatings in cars so equipped is to be at the expense of the Lessee unless otherwise
specified on the Rider. Commodity or mechanical damage to such linings or coatings shall be for the account of the Lessee.

ARTICLE 17:INTERIOR PREPARATION FOR COMMODITIES

Any cleaning or special preparation of the interior of cars to make them suitable for the shipment of commodities by or for Lessee during the term of the lease
shall be done at Lessee's expense unless otherwise agreed.

ARTICLE 18:RETURN OF CARSCLEANING

At the expiration of the lease term as provided in the Riders, Lessee shall, at its expense, return the cars to Lessor at the location and to the agent selected
by the Lessor empty, clean and free from residue, and in the same good condition as the cars were in when delivered, except for normal wear and tear. At the expiration, should car cleaning be
required, the Lessee shall bear the full cost of cleaning and the rental shall continue until the car is clean.

ARTICLE 19:MODIFICATIONS

Lessor and Lessee agree that if, at any time after the effective date of any Rider, changes in car design or equipment are required by the AAR, DOT, FRA or any
other governmental authority, Lessor may, at its option, perform all modifications so ordered and that the cost of those modifications shall be reflected in an increase in the monthly rental rate per
car according to the rental escalation formula shown on the Rider for that car.

ARTICLE 20:HIGH MILEAGE AND WEIGHT LIMITATION

Each car is limited to the number of total loaded and empty miles per calendar year shown on the Rider and is subject to a surcharge also shown on the Rider for
all excess miles.

Lessee
shall not exceed the weight limitations prescribed for operation of cars in unrestricted interchange service as set forth under Interchange Rule 91 without Lessor's prior
written consent.

ARTICLE 21:USE OF CARS ON CERTAIN ROADS UNDER AAR CIRCULAR OT-5

Upon the written request of Lessee (which request shall name the railroads involved) Lessor shall use reasonable efforts to obtain from each named railroad
authority to place the cars (other than tanks) in service under the provisions of AAR Circular OT-5 as promulgated by the Association of American Railroads and all supplements thereto and
reissues thereof (such authority hereinafter called "consent(s)"). Lessee shall furnish to Lessor such information as is necessary to apply for and obtain such consents. Lessor, however, shall not be
liable for failure to obtain such consents for any reason whatsoever and this Lease shall remain in full force and effect notwithstanding any failure of Lessor to obtain such consents.

ARTICLE 22:INDEMNIFICATIONS

Lessee shall defend (if such defense is tendered to Lessee), indemnify and hold Lessor harmless from and against and does hereby release Lessor from all claims,
suits, liabilities, losses, damages, costs and expenses, including attorney's fees, in any way arising out of, or resulting from, the condition,

5

---

assumed full responsibility and satisfies such responsibility.

Except
as otherwise provided herein, Lessor shall defend, indemnify and hold Lessee harmless form and against all claims, suits, liabilities, losses, damages, costs and expenses,
including attorney's fees, arising out of, or resulting from any negligent act or omission of Lessor.

ART1CLE 23:TAXES AND LIENS

shall be liable for and pay such taxes when cars bear reporting marks and numbers other than Lessor's and (ii) Lessee shall be liable at all times for and shall pay or reimburse Lessor for the
payment of any sales, use, leasing, operation, excise, gross receipts and other taxes with respect to the cars, together with any penalties, fines or interest thereon and all duties, imposts, taxes,
investment tax credit reductions and similar charges arising out of the use of cars outside the continental United States.

Lessee
acknowledges and agrees that by the execution of this Lease it does not obtain, and by payments and performance hereunder it does not, and will not, have or obtain any title to
the cars or any property right or interest therein, legal or equitable, except solely as Lessee hereunder and subject to all of the terms hereof. Lessee shall keep the cars free from any liens or
encumbrances created by or through Lessee.

ARTICLE 24:DEFAULT AND REMEDIES

If Lessee defaults in the payment of any sum of money to be paid under this Lease and such default continues for a period of ten (10) days after written
notice to Lessee of such default or if Lessee fails to perform any covenant or condition required to be performed by Lessee, which failure shall not be remedied within ten (10) days after
notice thereof by Lessor to Lessee or if Lessee shall dissolve, make or commit any act of bankruptcy or if any proceeding under any bankruptcy or insolvency statute or any laws relating to relief of
debtors is commenced by Lessee or if any such proceeding is commenced against Lessee and same shall not have been removed within thirty (30) days of the date of the filing thereof or if a
receiver, trustee or liquidator is appointed for Lessee or for all or a substantial part of Lessee's assets with Lessee's consent or, if without Lessee's consent, the same shall not have been removed
within thirty (30) days of the date of the appointment thereof or if an order, judgment or decree is entered by a court of competent jurisdiction and continues unpaid and in effect for any

Each
remedy is cumulative and may be enforced separately or concurrently. In the event of default, Lessee shall pay to Lessor upon demand all costs and expenses, including reasonable
attorneys' fee expended by Lessor in the enforcement of its rights and remedies hereunder, and Lessee shall pay interest on any amount owing to Lessor from the time such amount becomes due hereunder
at a rate per annum equal to three percentage points above the prime rate of Chase Manhattan Bank (or its successor), such rate to be reduced, however, to the extent it exceeds the maximum rate
permitted by applicable law. In addition, Lessee shall, without expense to Lessor, assist Lessor in repossessing the cars and shall, for a reasonable time, if required, furnish suitable trackage space
for the storage of the cars.

If
Lessee fails to perform any of its obligations hereunder, Lessor, at Lessee's expense, and without waiving any rights it may have against Lessee for such nonperformance, may itself
render such performance. Lessee shall reimburse Lessor on demand for all sums so paid by Lessor on Lessee's behalf, together with interest at a rate equal to three percentage points above the prime
rate of Chase Manhattan Bank(or its successor), such rate to be reduced, however, to the extent it exceeds the maximum rate permitted by applicable law.

All rights of Lessor hereunder may be assigned, pledged, mortgaged, leased, transferred or otherwise disposed of, either in whole or in part, and/or Lessor may
assign, pledge, mortgage, lease, transfer or otherwise dispose of title to the cars, with or without notice to Lessee. As a condition to any such assignment, pledge, mortgage, lease, transfer or other
disposition, Lessor shall have entered into a
management agreement with the assignee, pledgee, mortgagee, lessor, or other holder of legal title to or security interest in the cars for purposes of allowing such assignee, pledgee, mortgagee,
lessor or other holder of legal title to or security interest in the cars to perform Lessee's obligations hereunder. In the event of any such assignment, pledge, mortgage, lease, transfer or other
disposition, this Lease and all rights of Lessee hereunder or those of any person, firm or corporation who claims or who may hereafter claim any rights in this Lease under or through Lessee, are
hereby made subject and subordinate to the terms, covenants and conditions of any assignment, pledge, mortgage, lease, or other agreements covering the cars heretofore or hereafter created and entered
into by Lessor, its successors or assigns and to all of the rights of any such assignee, pledgee, mortgagee, lessor, transferee or other holder of legal title to or security interest in the cars.
During the term of this Lease no such assignee, pledgee, mortgagee, lessor, transferee or other holder of legal title to or security interest in the cars shall interfere with the quiet use, possession
and enjoyment of the cars by Lessee provided that no event of default or termination event (however described) shall have occurred under such assignment, pledge, mortgage, lease or other agreement and
provided that no event of default or termination event (however described) has occurred under this Lease and provided further that the exercise by assignee, pledgee, mortgagee, lessor, transferee or
other holder of legal title to or security interest in the cars of their respective rights under or in connection with such assignment, pledge, mortgage, lease or other agreement or this Lease shall
not constitute such an interference. Lessee hereby agrees that Lessor or such assignee, pledgee, mortgagee, lessor, transferee or other holder of legal title to or security interest in the cars may
terminate this Lease simultaneously with the

7

---

termination of any such assignment, pledge, mortgage, lease or other agreement and that upon such termination, Lessee shall redeliver the cars to Lessor. Any sublease or assignment of the cars
permitted by this Lease that is entered into by Lessee or its successors or assigns shall contain language which expressly makes such assignment or sublease subject to the subordination contained
herein. At the request of Lessor or any assignee, pledgee, mortgagee, lessor, transferee or other holder of the legal title to or security interest in the cars, Lessee, at Lessor's expense, shall
letter or mark the cars to identify the legal owner of the cars and, if applicable, place on each side of each car, in letters not less than one inch in height, the words "Ownership Subject to a
Security Lease Filed with the Surface Transportation Board" or other appropriate words reasonably requested.

In
the event that Lessor assigns its interest in this Lease, Lessee, at the request of Lessor, shall execute and deliver to Lessor an Acknowledgment of Assignment of Lease in form
satisfactory to Lessor and upon such request and execution furnish to Lessor an opinion of counsel that such Acknowledgment has been duly authorized, executed and delivered by Lessee and constitutes a
valid, legal and binding instrument, enforceable in accordance with its terms.

ARTICLE 26:WARRANTIES

LESSOR MAKES NO WARRANTIES OR REPRESENTATIONS, EXPRESS OR IMPLIED, AS TO THE CONDITION, MERCHANTABILITY, FITNESS FOR PARTICULAR PURPOSE OR ANY OTHER MATTER
CONCERNING THE CARS. LESSEE HEREBY WAIVES ANY CLAIM IT MIGHT HAVE AGAINST LESSOR FOR ANY LOSS, DAMAGE OR EXPENSE CAUSED BY THE CARS OR BY ANY DEFECT THEREIN. Lessee shall be solely responsible for
determining that the specifications and design of any car are appropriate for the commodities loaded therein. During the period of any lease hereunder in which Lessee renders faithful performance of
its
obligations, Lessor hereby assigns to Lessee any factory or dealer warranty, whether express or implied, or other legal right Lessor may have against the manufacturer in connection with defects in the
cars covered by this Lease.

ARTICLE 27:RIGHT OF INSPECTION AND NOTICES

Lessor, or its assignee, shall, at any reasonable time and without interfering with Lessee's operations, have the right to inspect the cars by its authorized
representative wherever they may be located for the purpose of determining compliance by Lessee with its obligations hereunder. Lessee shall use its best effort to obtain permission, if necessary, for
Lessor or its representative to enter upon any premises where the cars may be located.

Lessee
shall notify Lessor, in writing, within three (3) days after any attachment, lien (including any tax and mechanics' liens) or other judicial process attaches to the cars.

ARTICLE 28:MISCELLANEOUS

This Lease, together with any and all exhibits attached hereto, constitutes the entire agreement between Lessor and Lessee, and it shall not be amended, altered
or changed except by written agreement signed by the parties hereto. No waiver of any provision of this Lease or consent to any departure by Lessee therefrom shall be effective unless the same shall
be in writing, signed by both parties and then such waiver of consent shall be effective only in the specific instance and for the purpose for which it was given.
