NEW YORK CITY TRANSIT'S PILOT PROJECT FOR COMMUNICATIONS-BASED TRAIN CONTROL

New York City Transit (NYCT) is one of the oldest, largest, and most complex subway systems in the world. As part of its ongoing modernization program, NYCT plans to upgrade its signal system from fixed block/wayside signals to communications-based train control (CBTC) technology. CBTC technology was assessed as the best solution for NYCT's needs, offering enhanced performance, lowest life-cycle costs, and minimum operational disruption during implementation. Given the size of the NYCT subway system, the transition to CBTC technology must be implemented in stages over a number of years. The implementation strategy is further complicated by the fact that the NYCT track is a complex rail network of highly interoperable lines. As a consequence, CBTC-equipped trains that normally run on one line must also be capable of operating over other CBTC-equipped lines modernized both prior to and subsequent to equipping of the cars. A key element of NYCT's CBTC implementation strategy, therefore, is to establish interoperability interface standards that will permit independent procurement of wayside and trainborne CBTC equipment. NYCT's 20-year implementation strategy for CBTC is based on a procurement approach that uses the Canarsie line as the pilot project for proving the new technology and developing interoperability standards. This paper summarizes the status of this signal modernization program.
