 Timber Crosstie and Switch Tie 
 Procurement Specification 
  

	1.0	Scope – This procurement specification establishes the minimum detailed technical requirements for Timber Crossties and Timber Switch Ties for use by CSX. It is
CSX’s desire to enter into a long-term contract with suppliers of quality timber crossties and timber switch ties. The suppliers governed by this specification, shall have or establish a quality system that complies with and is certified to the
standards set forth in the AAR Specification for Quality Assurance, M1003 (AAR M-1003), or International Quality Standard ANSI 9000 Series (ISO 9001). 

  

	1.1	Crosstie & Switch Tie Description – Timber crossties and switch ties are used to secure, anchor and support rail, switch, and other track equipment. As
such, the consistent quality of crossties and switch ties is of the utmost importance to CSX for safety and track reliability. The crossties and switch ties acquired under this specification shall be used to meet CSX field requirements for initial
installation at new construction locations, replacement at existing sites, and also for modification at existing locations. Crossties and switch ties acquired for use by CSX shall as a minimum meet the material quality, dimensional, and processing
requirements of sections 3, 4, and 5 of this specification as directed and applied by the contract. 

  

	1.2	Requirements Rating Criteria – Assignment of specification importance shall be designated by one of the following: 

  

	 	(C)	– Critical Characteristic 

  

	 	(M)	– Major Characteristic 

  

	 	(I)	– Incidental Characteristic 

 This specification
covers two types of ties, timber crossties and timber switch ties. As such, in certain instances, functional requirements specified herein may not be applicable to a particular product. In those cases, the supplier shall respond to the requirement
as being not applicable, and explain why it is not. In other instances, in lieu of a defined requirement, this specification may ask for data, or a description for relative comparison.

	2.0	Applicable Documents – The latest issue of the following document forms a part of this standard to the extent specified herein: 

  

	 	•	 	 Applicable Federal, State, and local Regulations 

 In the event of a conflict between the document referenced here and the detailed content of section 3, 4, and 5, the detail requirements of sections 3, 4, and 5, shall be considered the superseding requirements.

  

	3.0	Requirements (C) – 

  

	3.1	General (I) – The information and requirements included in this section are applicable to timber crossties and switch ties as specified in sections 3.2 and 3.3
respectively of this document. 

  

	3.1.1	Definitions – 

  

	 	a)	Decay – Decay is the disintegration of wood substance material due to the action of destroying fungi. “Blue Stain” shall not be considered as decay and is
permissible in any wood used for ties. 

  

	 	b)	Rot – Is the decomposition of wood, which occurs due to age, decay, or chemical disintegration. 

  

	 	c)	Holes – Within the rail bearing area, a large hole is one more than 1/2 inch in diameter and 3 inches deep. Outside the rail bearing area, a large hole is one which is
1/4 the width of the surface on which it appears and 3 inches deep. Numerous holes are any number equaling a large hole in damaging effect. Such holes may be caused in manufacture or otherwise. 

  

	 	d)	Knots – Within the rail bearing area, a large knot is one having an average diameter more than 1/3 the width of the surface on which it appears; but such a knot will be
allowed if it is located outside the rail bearing area. Numerous small knots equaling the diameter of a large knot in damaging effect shall equate to a large knot and shall have the same limitations. 

  

	 	e)	Shake – A shake is a separation along the grain, most of which occurs between the rings of annual growth (see Figures A, B, & C below).

 Appendix D 
 Capacity Commitment for Customer’s Green Ties 
 The combined Capacity Commitment is * million ties, plus or
minus *%. The chart below reflects the specific monthly capacity for each Plant for dry ties. The capacity of a Plant is lower if the ties are to be boultonized. If *% of the ties to be treated at a Plant are to be boultonized, the capacity would be
*% lower than the Capacity Commitment set forth in the following chart: 
  

							
	 Kentucky
	  	South Carolina	  	West Virginia	  	Total Per Month
	 *
	  	*	  	*	  	*

 If Customer specifies that ties provided by Customer to Provider shall be boultonized, then the specific monthly
capacity of each Plant, as shown in the chart above, shall be decreased proportionately. By way of example and not limitation, should Customer specify that in January, * of the ties sent to the Florence, South Carolina Plant for treatment shall be
boultonized, then the South Carolina Plant’s January Capacity Commitment shall be * ties. Should Customer specify that in January * of the * ties sent to the Florence, South Carolina Plant for treatment shall also be boultonized, then the South
Carolina Plant’s January Capacity Commitment shall be * ties (* dry ties plus * less *%=*).Amendment No. 1 to Treatment Services Agreement

 Timber Crosstie and Switch Tie 
 Procurement Specification 
  

	1.0	Scope – This procurement specification establishes the minimum detailed technical requirements for Timber Crossties and Timber Switch Ties for use by CSX. It is
CSX’s desire to enter into a long-term contract with suppliers of quality timber crossties and timber switch ties. The suppliers governed by this specification, shall have or establish a quality system that complies with and is certified to the
standards set forth in the AAR Specification for Quality Assurance, M1003 (AAR M-1003), or International Quality Standard ANSI 9000 Series (ISO 9001). 

  

	1.1	Crosstie & Switch Tie Description – Timber crossties and switch ties are used to secure, anchor and support rail, switch, and other track equipment. As
such, the consistent quality of crossties and switch ties is of the utmost importance to CSX for safety and track reliability. The crossties and switch ties acquired under this specification shall be used to meet CSX field requirements for initial
installation at new construction locations, replacement at existing sites, and also for modification at existing locations. Crossties and switch ties acquired for use by CSX shall as a minimum meet the material quality, dimensional, and processing
requirements of sections 3, 4, and 5 of this specification as directed and applied by the contract. 

  

	1.2	Requirements Rating Criteria – Assignment of specification importance shall be designated by one of the following: 

  

	 	(C)	– Critical Characteristic 

  

	 	(M)	– Major Characteristic 

  

	 	(I)	– Incidental Characteristic 

 This specification
covers two types of ties, timber crossties and timber switch ties. As such, in certain instances, functional requirements specified herein may not be applicable to a particular product. In those cases, the supplier shall respond to the requirement
as being not applicable, and explain why it is not. In other instances, in lieu of a defined requirement, this specification may ask for data, or a description for relative comparison. 

 MW-99001 (Rev. B) 
 7/12/05 Page 2 of 20 
  

	2.0	Applicable Documents – The latest issue of the following document forms a part of this standard to the extent specified herein: 

  

	 	•	 	 Applicable Federal, State, and local Regulations 

 In the event of a conflict between the document referenced here and the detailed content of section 3, 4, and 5, the detail requirements of sections 3, 4, and 5, shall be considered the superseding requirements.

  

	3.0	Requirements (C) – 

  

	3.1	General (I) – The information and requirements included in this section are applicable to timber crossties and switch ties as specified in sections 3.2 and 3.3
respectively of this document. 

  

	3.1.1	Definitions – 

  

	 	a)	Decay – Decay is the disintegration of wood substance material due to the action of destroying fungi. “Blue Stain” shall not be considered as decay and is
permissible in any wood used for ties. 

  

	 	b)	Rot – Is the decomposition of wood, which occurs due to age, decay, or chemical disintegration. 

  

	 	c)	Holes – Within the rail bearing area, a large hole is one more than 1/2 inch in diameter and 3 inches deep. Outside the rail bearing area, a large hole is one which is
1/4 the width of the surface on which it appears and 3 inches deep. Numerous holes are any number equaling a large hole in damaging effect. Such holes may be caused in manufacture or otherwise. 

  

	 	d)	Knots – Within the rail bearing area, a large knot is one having an average diameter more than 1/3 the width of the surface on which it appears; but such a knot will be
allowed if it is located outside the rail bearing area. Numerous small knots equaling the diameter of a large knot in damaging effect shall equate to a large knot and shall have the same limitations. 

  

	 	e)	Shake – A shake is a separation along the grain, most of which occurs between the rings of annual growth (see Figures A, B, & C below). 

 MW-99001 (Rev. B) 
 7/12/05 Page 3 of 20 
  

 

 
 The procedure illustrated in the above diagrams shall be used in determining the length of the shake. One which
is not more than 1/3 the width of the tie shall be allowed, provided it does not extend nearer than 1 inch to any surface. Multiple ring shakes shall not be allowed. 
  

	 	f)	Split – A split is a separation of the wood extending from one surface to an opposite or adjacent surface. 

  

	 	1)	In unseasoned ties, a split no more than 1/8 inch wide and/or 4 inches long is acceptable when antisplitting devices have been applied and the tie is brought back to its original
sawn dimensions. 

  

	 	2)	In a seasoned tie, a split no more than 1/4 inch wide and/or longer than the width of the face across which it occurs is acceptable when antisplitting devices have been applied and
the tie is brought back to its original sawn dimensions. 

 MW-99001 (Rev. B) 
 7/12/05 Page 4 of 20 
  

	 	3)	Multiple splits of no more than a three way split are acceptable. 

  

	 	4)	In no instance will a tie be considered acceptable when a split extends into the rail bearing area. 

  

	 	g)	Checks – 

  

	 	1)	For procurement of seasoned ties: A check is a “V” shape groove in a tie similar to a cut made with an ax. A check is acceptable provided it is not more than 3/8
inch wide, the depth not greater than 1/2 the thickness of the tie, and does not extend into the rail bearing area. 

  

	 	2)	For treatment of seasoned ties: A check is acceptable provided it is not more than 1/2 inch wide, the depth not greater than 1/2 the thickness of the tie, and does not extend
into the rail bearing area. 

  

	 	h)	Bark Seams – Bark seams will not be acceptable if they appear in the rail bearing area. A bark seam or pocket is a patch of bark partially or wholly enclosed in the
wood. Bark seams will be allowed provided they are not more than 2 inches below the surface and/or 10 inches long. 

  

	 	i)	Wood Destroying Insect Infestation – A wood destroying insect infestation is the presence of insects known to destroy wood and other cellulose materials, such as
termites, carpenter ants, etc. If an infestation exists, the type of insect will be identified. If termites are detected, the identification must distinguish between Formosan Subterranean termites, and other termite species.

  

	 	1)	All ties shall be inspected for and protected from infestation. 

  

	 	2)	If an infestation is found, the tie is not acceptable for use on CSX. 

  

	 	3)	Ties infected with other than Formosan Subterranean Termites will be disposed of in an appropriate manner determined by the supplier. 

  

	 	4)	Ties infested with Formosan Subterranean Termites shall be treated to kill the termites and disposed by burning in an environmentally appropriate facility. 

 

	 	j)	Slanting Grain – Except in woods with interlocking grain, a slant in grain in excess of 1 in 15 will not be permitted, and/or if present in rail bearing area.

  

	 	k)	 Excessive Wane – Examples of this defect have been 

 MW-99001 (Rev. B) 
 7/12/05 Page 5 of 20 

	 	

	 	termed in the industry as “Saddlebacks” and “Sledruners”. These conditions in ties shall not be considered acceptable and are illustrated and further defined
below. 

  

	 	1)	Saddlebacks – Saddlebacks between the rail base area will not be accepted if lack of face is more than 1/2 the width (see Fig. D, below). 

  

	 	2)	Sledrunner – A sledrunner appearing on the end of a tie will not be accepted if lack of face is more than 1/2 the thickness and more than 3 inches from end of tie (see
Fig. E, below).

 Appendix D 
 Capacity Commitment for Customer’s Green Ties 
 The combined Capacity Commitment is * million ties, plus or
minus *%. The chart below reflects the specific monthly capacity for each Plant for dry ties. The capacity of a Plant is lower if the ties are to be boultonized. If *% of the ties to be treated at a Plant are to be boultonized, the capacity would be
*% lower than the Capacity Commitment set forth in the following chart: 
  

							
	 Kentucky
	  	South Carolina	  	West Virginia	  	Total Per Month
	 *
	  	*	  	*	  	*

 If Customer specifies that ties provided by Customer to Provider shall be boultonized, then the specific monthly
capacity of each Plant, as shown in the chart above, shall be decreased proportionately. By way of example and not limitation, should Customer specify that in January, * of the ties sent to the Florence, South Carolina Plant for treatment shall be
boultonized, then the South Carolina Plant’s January Capacity Commitment shall be * ties. Should Customer specify that in January * of the * ties sent to the Florence, South Carolina Plant for treatment shall also be boultonized, then the South
Carolina Plant’s January Capacity Commitment shall be * ties (* dry ties plus * less *%=*).
