Section 705.020 - Overhead clearances

1. The minimum overhead clearance above the top of rail of railroad tracks which are used or proposed to be used for transporting freight cars, for all overhead structures except as hereinafter prescribed, must be 22 feet.

2. The overhead clearance above top of rail of such tracks located inside of buildings which are entirely enclosed may be reduced to 18 feet. This clearance applies only to tracks terminating within the building. When an overhead clearance of less than 22 feet is established on tracks inside the building, all cars, trains, motors, engines or other equipment must be brought to a stop before entering the building.

3. Overhead clearances authorized in this section are applicable to tracks on which freight cars having a height to running board of 15 feet 1 inch or less are transported. On tracks over which freight cars of greater height are transported or proposed to be transported, minimum overhead clearances are increased by an amount not less than such additional height, except where the nature of the cars precludes the probability of employees getting on top of or passing over them.
