General Requirements
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.
