The provisions of this chapter prescribe reasonable requirements governing the clearances above, beside, and between railroad tracks in the District of Columbia that are intended to prevent accidents and injuries to employees, and to reduce the human suffering and economic loss that result from injuries.
In all construction or reconstruction of railroad tracks or structures adjacent to railroad tracks, and on all railroads over which freight cars are operated or proposed to be operated, the minimum clearances authorized in this chapter shall be provided.
A railroad company shall not operate freight cars, locomotives, or other freight rolling equipment over tracks constructed after September 1, 1958, or over tracks adjacent to buildings constructed or reconstructed after September 1, 1958, if the clearances are less than those prescribed in this chapter.
