Communications Based Train Control Interoperability Developments at New York City Transit

摘要

The Signals and Train Control Division of the Capital Program Management department of New York City Transit has embarked on a project that will develop, demonstrate and certify interoperable elements of Communications Based Train Control (CBTC) between two prequalified suppliers, Thales and Siemens. CBTC interoperability requires that the equipment from one supplier, for both the wayside and train, fully function and interface with the corresponding equipment from another supplier in all combinations, i.e., Siemens train equipment with Thales wayside, and Thales train equipment with Siemens wayside. Developing a standard, to which all suppliers of CBTC systems must design, will not only identify the interoperability requirements, but also the interfaces, particularly those elements being provided by the Authority that define the radio and transponder interface. Safety certification will also be an important outcome of the demonstration.
