Primary Guidance

  • Rail stations typically include a station platform and passenger circulation elements.
  • Station platforms should meet specific minimum/maximum criteria for size and slope.
  • Passenger circulation should be designed to support normal operations as well as emergency evacuation. Circulation Discussion.
  • Rail stations should be designed to meet applicable codes, including NFPA 130 and the Americans with Disabilities Act Accessibility Guidelines.

Discussion

Rail stations are an integral component of an overall transit system and may be at-grade, aerial, or underground. Rail stations should be designed to meet NFPA 130 and Americans with Disabilities Act Accessibility Guidelines.

Rail station elements may include any or all of the following: station platform(s); passenger circulation elements such as stairs, ramps, elevators, escalators; and platform elements such as canopies and shelters that provide weather protection. Stations should always provide adequate and intuitive means for emergency evacuation.

Station Platforms

Station platforms should provide level convenient and accessible boarding.

  • Maximum slope for at grade platforms should be 1.75%; for underground and aerial station, 0.5%; and for all stations, platform cross slope should be flat.
  • Station platform size (length and width) will be determined by the design vehicle length, level of service (LOS), ridership projections and other design criteria.
  • Platform length should be scalable to facilitate expansion between day of opening and horizon year projections.
  • Minimum platform width for side a platform is 10 feet and 15 feet for a center/island platform.
  • Canopies, shelters, and screens should provide protection from wind, rain, snow and sun and be sized for the convenience and comfort of patrons. They should be modular and discretely sized to meet the basic needs of the project yet facilitate platform expansion.
  • Design considerations for modularity and scalability provide the best value at day of opening without precluding future expansion.
  • Future maintenance will also be a key design consideration. Platforms should meet 20 year horizon LOS C criteria for queuing. Platform slopes should be designed as follows:


Platform Slope Maximum longitudinal slope for at-grade stations. 1.75%
Maximum longitudinal slope for underground and aerial stations. 0.50%
Station cross slopes should be flat for safety, but if required for improved drainage, slope away from platform edge at a

maximum cross slope.

1.00%


Passenger

Circulation

Vertical Circulation Elements (VCEs),- Ramps, Stairs, Escalators and Elevators
1. Use of sloping walkways in lieu of ramps and ramps in lieu of elevators where feasible, is acceptable.

Note: For a vertical rise less than 8 feet, elevators and lifts shall be used only when unavoidable due to space constraints.

Less than 12 feet.
2. Elevators are required for disabled access within the station for vertical rise greater than 12 feet. Stairs are required as well. 12 feet to 16 feet.
3. Use paired escalators and stairs. Escalators, shall be the primary for ascent and stairs primary for descent.

Note: Escalators may be replaced with primary passenger elevators if LOS analysis yields an average wait time of 45 seconds or less, using not less than 2.5 square feet,/passenger to determine capacity.

16 feet to 20 feet.
4. Use elevators and escalators. Stairs shall not be considered a means of normal public ascent or descent where the vertical rise between levels exceeds 20 feet.

Note: Escalators may be replaced with primary passenger elevators if LOS analysis yields an average wait time of 45 seconds or less using not less than 2.5 square feet /passenger to determine capacity.

Greater than 20 feet.
Vertical Clearance 1. Minimum headroom over primary stair or escalator measured perpendicularly from edge of tread nosing to underside of ceiling or overhead construction. 10 feet.
2. Minimum headroom at ceiling structures such as signage. 8 feet 6 inches.
Elevators

Note: Elevators shall comply with APTA RT-RP-FS-007-02; ASME A17.1; ADAAG

1. Minimum queuing in front of elevator doors. 1.5 x Depth of Cab
2. Minimum overhead protection for elevator doors exposed to the outdoor with street level landings. 6 feet x feet of each cab.
3. Where primary passenger elevators are required along a primary circulation route, minimum capacity required. 20 persons, 4500-pound capacity.
4. All elevator cabs shall be sized to accommodate a 24 feet x 84 feet ambulance stretcher in horizontal, open position. Provide ADA and gurney elevators in all locations where elevators are warranted. 16 persons, 4000-pound capacity.
5. Minimum door sizes to accommodate wheelchairs, gurneys. 3 feet 6 inches wide x 7 feet 8 inches high.
6. Minimum speed of elevators at passenger carrying capacity. 200 feet per minute.
Site Walkways Minimum width 5 feet.
Minimum vertical clearance 8 feet.
Pedestrian at-grade crossing minimum width 12 feet.
Through bus stop and Park & Rides 10 feet.
Crossing connecting walkways 10 feet.
Pedestrian tunnels 16 feet.
Walkway track crossing serving primary entrances 30 feet.
