Section 1192.51 General.
(a) New, used and remanufactured rapid rail vehicles, to be considered
accessible by regulations issued by the Department of Transportation in 49 CFR
part 37, shall comply with this subpart.
(b) If portions of the vehicle are modified in a way that affects or
could affect accessibility, each such portion shall comply, to the extent
practicable, with the applicable provisions of this subpart. This provision

required. Vehicles previously designed and manufactured in accordance with the
accessibility requirements of 49 CFR part 609 or Department of Transportation
regulations implementing section 504 of the Rehabilitation Act of 1973 that
were in effect before October 7, 1991 and which can be entered and used from
stations in which they are to be operated, may be used to satisfy the

provided, and if such doorway is connected by an aisle with a minimum clear
width of 30 inches to one or more spaces where wheelchair or mobility aid
users can be accommodated, then such doorway shall have a minimum clear
opening of 30 inches to permit wheelchair and mobility aid users to be
evacuated to an adjoining vehicle in an emergency.
(b) Signage. The International Symbol of Accessibility shall be
displayed on the exterior of accessible vehicles operating on an accessible
rapid rail system unless all vehicles are accessible and are not marked by the
access symbol. (See Fig. 6)
(c) Signals. Auditory and visual warning signals shall be provided to
alert passengers of closing doors.
(d) Coordination with boarding platform. - (1) Requirements. Where new
vehicles will operate in new stations, the design of vehicles shall be
coordinated with the boarding platform design such that the horizontal gap
between each vehicle door at rest and the platform shall be no greater than 3
inches and the height of the vehicle floor shall be within plus or minus 5/8
inch of the platform height under all normal passenger load conditions.
Vertical alignment may be accomplished by vehicle air suspension or other
suitable means of meeting the requirement.
(2) Exception. New vehicles operating in existing stations may have a
floor height within plus or minus 1-1/2 inches of the platform height. At key
stations, the horizontal gap between at least one door of each such vehicle
and the platform shall be no greater than 3 inches.
(3) Exception. Retrofitted vehicles shall be coordinated with the
platform in new and key stations such that the horizontal gap shall be no
greater than 4 inches and the height of the vehicle floor, under 50% passenger
load, shall be within plus or minus 2 inches of the platform height.
Setion 1192.55 Priority seating signs.
(a) Each vehicle shall contain sign(s) which indicate that certain seats
are priority seats for persons with disabilities, and that other passengers

ratio between 1:5 and 1:10, with a minimum character height (using an upper
case "X") of 5/8 inch, with "wide" spacing (generally, the space between
letters shall be 1/16 the height of upper case letters), and shall contrast

(b) Handrails, stanchions, and seats shall allow a route at least 32
inches wide so that at least two wheelchair or mobility aid users can enter
the vehicle and position the wheelchairs or mobility aids in areas, each
having a minimum clear space of 48 inches by 30 inches, which do not unduly
restrict movement of other passengers. Space to accommodate wheelchairs and
mobility aids may be provided within the normal area used by standees and
designation of specific spaces is not required. Particular attention shall be
given to ensuring maximum maneuverability immediately inside doors. Ample
vertical stanchions from ceiling to seat-back rails shall be provided.
Vertical stanchions from ceiling to floor shall not interfere with wheelchair
or mobility aid user circulation and shall be kept to a minimum in the
vicinity of doors.
(c) The diameter or width of the gripping surface of handrails and
stanchions shall be 1-1/4 inches to 1-1/2 inches or provide an equivalent
gripping surface and shall provide a minimum 1-1/2 inches knuckle clearance
from the nearest adjacent surface.
Section 1192.59 Floor surfaces.
Floor surfaces on aisles, places for standees, and areas where

(b) Exception. Between-car barriers are not required where platform
screens are provided which close off the platform edge and open only when
trains are correctly aligned with the doors.
