* The CFR reference sections noted throughout the check list refers to the actual regulatory requirement.
Footnotes:
1 TB MP&E 98-53 ...d inch alloy chain and ½ inch steel alloy chain currently being used by new car manufacturers exceed the specifications.
2 TB MP&E 98-18 Ladder treads, handholds of circular cross-section, 13/16 inch diameter and sill steps, e inch thick and 2 inches wide, when constructed of
6061-T6 aluminum alloy exceeds the current Federal Railroad Administration's requirements.
3 Equivalent must meet or exceed the cross sectional area the result of which may not be less than ¾ inch.
4 TB MP&E 98-13 Clear depth means a vertical space the width of, and above the sill step material or strap and should be clear and unobstructed for 8 inches
5 Variance allowed due to construction of car. Note exception on F6180.4.
IMPORTANT NOTE: Equipment that is not adequately addressed in Part 231. For examples: There are no ladder requirements in §§231.29 or 231.30.
However, if additional safety appliances are used on any type of equipment, (i.e., §231.18 Cars of special construction), they must meet the dimension, location, and
a manner of application requirements. This logic holds true regardless of the equipment inspected. When applying §231.6 during a sample-car inspection on an
auto rack, you will encounter components not mentioned in that section such as ladders, stenciling, end ladder clearance, etc. These additional components must
meet the appropriate requirements. If there is any doubt, consult your regional specialist.
Pubic reporting burden for this information collection is estimated to average 60 minutes per response. This estimate includes the time for reviewing each page of the
checklist. According to the paperwork Reduction Act of 1995, no persons are required to respond to a collection of information unless it displays a valid OMB control
number. The valid OMB control number for this collection of information is 2130-XXXX.
