9.3 RAIL VEHICLES

9.3.1 Introduction

This section summarizes the required functional, operational, and physical characteristics of

Metro Transit Rail Vehicles. This section is intended to provide a definition of the vehicles

to assist in the design of fixed facilities as well as to serve as a source of information to

other designers. All future vehicle procurements will be defined on the basis of equipment

previously procured to assure operating compatibility and optimized logistics. All vehicles

shall be in accordance with all rules and regulations of the Americans with Disabilities Act

(ADA), and other related regulatory provisions of other government agencies having

jurisdiction shall be used for additional guidelines.

9.3.2 Vehicle Characteristics

A. General

The vehicles defined in this Section will be for Light Rail Projects. The vehicles

may be of the articulated or married-pair type, double ended, four doors on each

side for articulated type and three doors per side for the married pair type, with

access from high-level platforms. The vehicles shall utilize in design and

construction as much" off-the-shelf" technology as possible. The center truck

shall be unpowered if the vehicle is of the articulated type. The design minimum

service life of the vehicles shall be 30 years. Each lead vehicle in a consist shall

be equipped with at least a horn and headlight to assist in alerting station

occupants to an arriving train. Materials shall be based on characteristics of:

 Resistance to vandalism and graffiti.

 Ease of cleaning and maintenance.

 Compliance with fire, smoke emission and to industry standards.

B. Operating Characteristics

Vehicles shall be capable of operating as single units or as multiple units

consisting of two or three Light Rail vehicles and in an emergency operation of

up to twice that number of vehicles. The vehicles shall be designed as a

minimum, for manual operation with an Automatic Train Protection (ATP) system

to enforce system imposed maximum speeds.

Vehicles shall also be capable of operation without ATP, or Automatic Train

Supervision (ATS) if necessary due to an emergency situation or an ATP or ATS

system failure, or if in uncontrolled territory. A configuration that allows for

driverless operation may also be considered. Driverless criteria will be

developed at that time.
