**Scoping**

 **General**
. o **Rapid rail** (e.g., subway) and **high -** **speed rail** cars purchased after the effective date of these requirements (to be determined by DOT) shall be designed for full
length platform level boarding and meet the provisions of this section. In stations constructed on or after January 26, 1992, all car doors through which passengers board and alight shall meet the gap requirements set forth below. In stations constructed prior to January 26, 1992, at least one door serving each on board seating area for wheelchairs and mobility aids shall meet these requirem ents. o All doors on **light rail** cars and **commuter rail** cars operating exclusively at level boarding station platforms shall comply with the gap requirements. At least one door through which passengers board and alight on each side serving each on
board se ating area for wheelchairs and mobility aids of **intercity rail** cars, and **commuter rail** cars operating at mixed high and low platforms, shall meet these requirements. All doors on **AGT (people mover)** cars operating at speeds of 20 mph or slower shall meet t he requirements for “people movers” set forth below.  **Boarding and Alighting. A**  ll new rail and fixed guideway vehicles shall be compatible with level boarding. All steps shall incorporate a trap to cover the steps and bring the car floor level to the doorway. Doorways shall have a minimum vertical clearance of 74 inches from the closed trap to the lintel.  **Gaps.** Wherever either or both of the conditions in (i) and (ii) are met, a car
- borne ramp or bridgeplate or a car
- borne lift shall be employed: o (i) the horizontal gap between the boarding platform and the vehicle floor exceeds 2 inches o (ii) the vertical difference between the boarding platform height and the vehicle floor exceeds plus or minus 5/8 inches.2

 **People Movers.** The horizontal gap between pl atform and car floor shall not exceed 25 mm (1 inch). The vertical difference between platform and car floor shall not exceed plus or minus 5/8 inch.  **Operation.** Where car doors open automatically at platforms designed for level boarding, ramps and bridge plates shall deploy automatically prior to door opening and stow automatically after doors close. Manually deployed ramps and bridgeplates shall be permitted where doors are opened by train personnel and where the horizontal gap exceeds 300 mm (12 inches)
.  **Advisory Operation,** The Committee recognizes that any gap between a rail vehicle and a platform can be a safety hazard for all travelers. The Committee recommends that the Board require all entries on new vehicles to have automated bridgeplates or ramps where gaps exist at platforms by the year 2020.
**Ramps and Bridgeplates**

 **General.** Ramps and bridgeplates shall comply with this section
. Ramps and bridgeplates shall be permitted to fold or telescope if all the technical requirements are met.  **Design Load.**  The design load of ramps and bridgeplates 760 mm (30 inches) or more in length shall be 364 kg (800 pounds ) minimum. The design load of ramps and bridgeplates less than 760 mm (30 inches) in length shall be 182 kg (400 pounds ) minimum. Ramps and b ridgeplates shall have a design safety factor of at least 3, based on the ultimate strength of the material. o **Advisory Design Load.** The design load is the weight the ramp or bridgeplate is designed to support without damage or permanent deformation. Some deflection may occur under maximum load.

 **Handrails.** Handrails complying with [fill in latest version of specifications for Handrails, Stanchions, and Handhol d s ] shall be provided on ramps and bridgeplates where the horizontal gap between platform and car floor exceeds 300 mm (12 inches).  **Clear Width.** The ramp and bridgeplate clear width shall be 800 mm (32 inches ) minimum. o **Advisory Clear Width.** A wider ramp or bridgeplate is recommended because it is more usable by passengers who use wheelchairs, and accommodates a broader range of passengers with disabilities.3

 **Attachment.** When used for boarding and alighting, ramps and bridgeplates shall be firmly attached to the vehicl e, shall not be subject to displacement from the vehicle, and shall overlap the platform
.  **Manual Operation.**  Power operated ramps and bridgeplates shall be capable of being operated manually and in a manner that is safe for the occupant and operator if the power fails.  **Surfaces.** Ramp and bridgeplate surfaces shall comply with [fill in latest version of specifications for Surfaces] , and shall be uninterrupted from edge to edge. o **Advisory Surfaces.** Ramp and bridgeplate surfaces must be uninterrupted from edge to edge to accommodate three
-wheel scooters. Expanded metal or perforated materials are permitted, as long as the openings comply with [fill in latest version of specifications for Openings]
.  **Edge Barriers.** The edges of ramps and bridgeplates shall have barriers 51 mm (2 inches) high minimum extending from the vehicle doorway to 6 inches from the outer end, and shall taper down smoothly
.  **Slope.** Ramps and bridgeplates shall have slopes not steeper than 1:8 (12.5 percent) when deployed to station platfor ms, . measured at 50 percent passenger load. o **Advisory Slope.** The Department of Transportation regulations at 49 CFR 37.165(f) require vehicle operators to assist passengers with disabilities with the use of boarding devices, even if the vehicle operators must leave their seats. Providing ramps and bridgeplates with the least possible slope accommodates a broader range of passengers wit h disabilities and minimizes the need for assistance.  **Transitions.** Surface discontinuities at transitions from boarding and alighting areas to ramps and bridgeplates shall comply with [fill in latest version of specifications for Surface Discontinuities]
.  **Visual Contrast.** The perimeter of the ramp and bridgeplate surface shall be outlined. The outline shall be 25 mm (1 inch) wide minimum and shall contrast visually with the rest of the ramp and bridgeplate surface either light
-on -dark or dark
- on - light.  **G aps.**  When deployed for boarding and alighting, gaps between the ramp or bridgeplate surface and vehicle floor and the ramp or bridgeplate surface and the station platform shall not permit passage of a sphere more than 16 mm (5/8 inch) in diameter.  **Stowage .**  Where portable ramps or bridgeplates are permitted, a compartment, securement system, or other method shall be provided within the vehicle to stow the ramps and bridgeplates when not in use. When stowed in passenger areas, portable ramps and bridgeplat es shall not pose a hazard to passengers, and shall not interfere with the maneuvering of wheelchairs.4

**Lifts General.** 

 **Design Load.** The lift design load shall be 364 kg (800 pounds ) minimum. Load carrying components that are subject to wear shall have a design safety factor of at least six, based on the ultimate strength of the material. Other components that are not subject to wear shall have a design safety factor of at least three, based on the ultimate strength of the material. **Controls.**

 **Interlocks.** Lift controls shall be interlocked with the vehicle brakes, transmission, propulsion system, or door, or shall provide other systems to prevent the vehicle from moving when the lift is not st owed. Lift controls shall not be operable unless the interlocks are engaged.  **Sequence.** Lift controls shall be of a momentary contact type requiring continuous manual pressure. Lift controls shall permit the operator to change the operation sequence. Lift controls shall not permit the lift platform to be folded, retracted, or stowed when occupied, unless the platform is designed to be occupied when stowed in the passenger area of the vehicle. o **Advisory Sequence.** A rotary lift is an example of a lift platform that is designed to be occupied when the platform is rotated into a stowed position in the passenger area of the vehicle.  **Manual Operation.** Lifts shall be capable of being operated manually if the power to t he lift fails. The manual operation shall be safe for the occupant and operator when operated according to the manufacturer’s instructions. When operated manually, the lift platform shall deploy and lower to the boarding and alighting area or the roadway with an occupant; shall rise to the vehicle floor without an occupant; and shall stow. The lift platform shall not fold, retract, or stow when occupied, unless the platform is designed to be occupied when stowed in the passenger area of the vehicle.
