Section 33.121 - Overhead clearances

(a) Minimum overhead clearances above railroad tracks, used or proposed to be used for transporting freight cars, shall be 22 feet, except as provided in this Subchapter. Structures constructed, or under construction, prior to the adopting of this Subchapter may be maintained at existing clearances and additional tracks may be constructed and existing tracks reconstructed at the same clearance.

(b) Overhead clearance above the top of rail of such tracks located at the entrance and inside of buildings may be reduced to 18 feet; if an overhead clearance of less than 22 feet exists on tracks inside such buildings, movements of railway equipment shall be brought to a stop before entering such buildings. In switching movements requiring a number of entries, stopping is required only upon initial entry.

(c) Clearances provided in this section do not apply to electric wires and equipment required over present and future tracks for the operation of trains by electric energy, provided the carriers concerned promulgate and enforce rules which prohibit any employe from being on top of cars while being operated under lower clearances than provided in this section.

(d) Clearances provided in this section do not apply to enginehouses, enginehouse facilities, tipples, or facilities used for servicing cars or for loading or unloading of bulk commodities, if such compliance is not reasonably practicable.
