36 CFR Parts 1190 and 1191 ADA and ABA Accessibility Guidelines - Preamble (Discussion of Comments and Changes)

Comment. Commenters advised that the specifications should address platforms for light rail vehicles which should be allowed to conform to the grade of the street.

Response. The Board has explicitly specified that rail platforms shall slope no more than 1:48 in any direction, consistent with cross slope provisions for walking surfaces in section 403. An exception has been added for platforms at existing tracks or tracks laid in existing roadways (810.5.1). Such platforms are permitted to have a slope parallel to the track that is equal to the slope (grade) of the roadway or existing track.
