R143 train on the Canarsie Line
Project Description
MTA-New York City Transit (NYCT) selected the Parsons-led Advanced Technology Systems Group (ATSG) consortium to develop performance specifications and manage system selection, system design review, oversight of factory and field testing, and commissioning of their pilot communications based train control (CBTC) system. The project required expertise in all types of train control technologies, operations, advanced spread spectrum communications, vehicle engineering, safety-critical systems, software development and evaluation, testing and commissioning, and form-fit-function specification development and validation. The Parsons’ team worked in partnership with NYCT and the supply industry to introduce communications based technology onto a 24/7 operating system and to re-signal the Canarsie Line.
The CBTC system entered revenue service in phases and was operational throughout the full line, including the Canarsie Yard on November 22, 2006. Automatic train operation is due to start service shortly.
The Parsons' team defined system requirements, developed system architecture and concepts, drafted contract documents, supported NYCT during the bid period, and selected suppliers for a system demonstration. The lead supplier’s interoperability interface specifications have been used by a follower contractor to re-engineer their system and demonstrate interoperability in the factory and on a test track in New York. The interoperability factory and field tests have been successfully completed. This will qualify two suppliers to bid for the next CBTC implementation. NYCT’s ongoing capital program for modernization of the signal system to maintain a state-of-good-repair is using this new standard.
Other key elements of the project include design of an auxiliary wayside system with relay-based interlockings, systems integration of CBTC with new train procurement, integration with the control center modernization program, operations and maintenance planning, drafting new rules and procedures, and a comprehensive training program for train operators, dispatchers, maintainers, shop staff, and engineers.
Parsons is a worldwide leader in the development, design, and implementation of CBTC Systems on new start transit systems and the retrofit of CBTC on established operations replacing convention wayside based signaling and train control.
