Light rail permanent-way requirements and sources. Paper presented at the National Conference of the Transportation Research Board, Philadelphia, June 1975.

The paper sets forth the technical requirements for the permanent way needed in construction of light rail transit facilities and then develops sources of assembling rights- of- way. Described are the physical capabilities of light rail transit for grade, curves, and clearances. Requirements for the guideway are established with the development of standards for track work suited to light rail transit. General requirements for stations are set forth with emphasis on space needs.
