Section 1546.20  General Requirements

a)         Walkways may be surfaced with asphalt, concrete, planking, grating,

native material, crushed material, or other similar material.  When crushed material is used, 100% of the material must be capable of passing through a 1½" square sieve opening and 90-100% of the material must be capable of passing through a 1" square sieve opening, provided, however, a de minimus variation shall not be a violation of this Part in an instance where the rail carrier has made a good faith effort to comply with the percentage requirements.  Smaller crushed material is preferable.  It should be used where drainage and durability issues do not arise.  Material that is ¾" or less in size is recommended for switching lead tracks.  

b)         Walkways must have a reasonably uniform surface and must be maintained in a safe condition without compromising track drainage.

c)         Cross slopes for walkways shall not exceed 1" of elevation for each 8" of horizontal length in any direction.

d)         Walkways shall be a minimum width of 2 feet.

e)         Walkways within the scope of this Part shall be kept reasonably free of

spilled fuel oil, sand, posts, rocks, and other hazards or obstructions.
