Simplification of Wayside Train Control Architecture

The MTA seeks proposals for redesigning the wayside Communication Based Train Control ("CBTC") equipment, including the Auxiliary Wayside System ("AWS") which interfaces between the CBTC system and the existing legacy wayside signaling equipment. The MTA's current approach to deploying CBTC with the required AWS is to equip each relay room with a solid state interlocking or relay-based interlocking system, programable logic controllers, local control panels, and zone controllers with associated network connections and power distribution. The MTA seeks proposed solutions that result in lower costs for design, layout and construction of the relay rooms and reduced reliance on track outages to test the completed train control system before deployment. Please direct all communications related to this RFI, including all responses, to me by email at fabrizio.raho@mtacd.org.The MTA Construction and Development Company ("MTA C&D") is issuing the enclosed Request for Information ("RFI") for proposed solutions for simplifying the existing wayside train control architecture.
