Abstract

New York City Transit's pilot project for communications-based train control A. F. Rumsey Parsons Transportation Group, New York, U.S.A. Abstract New York City Transit (NYCT) is one of the oldest, largest and most complex subway systems in the world, and as part of its ongoing modernisation 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 operati
