Communications Based Train Control (CBTC)

Communications Based Train Control (CBTC)

LB Transportation Consulting provides Communications Based Train Control (CBTC) services including design and testing.


Below are some of current CBTC engagements:


MTA: Communications Based Train Control Crosstown and Fulton Street (2022 to present) subcontractor to WSP:


The Base Scope of the Communications Based Train Control (CBTC) Program PM services consists of project management, construction management, oversight and administrative services for design-build projects deploying CBTC systems on two NYCT subway lines that span from approximately:


1) the Court Square Interlocking to the Church Avenue Interlocking (the “Crosstown Line”) and

2) the York Street Interlocking and the Jay Street Interlocking to the Church Avenue Interlocking (the “Fulton





The CBTC Program will replace and modernize the current NYCT subway signaling system with state-of-the-art CBTC technology to improve safety, reliability, operating efficiency, and provide for future capacity growth. CBTC is the accepted industry signaling standard and will provide significant benefits to the MTA and its customers.


The CBTC Program will include the installation of wayside CBTC equipment on the Crosstown Line and the Fulton Line, with options for segments, or all, of the 6th Ave/63rd St. Line (each line individually referred to as a “Program Line” and collectively, the “Program Lines”).


MTA: Pennsylvania Station Access (2022 to present) subcontractor to WSP:


Direct Metro-North service from the Bronx, Westchester, and Connecticut to Penn Station and Manhattan’s west side will be achieved with the Penn Station Access program. It will bolster equity, regional connectivity and reliability by delivering a new transit option.


With four new ADA-accessible passenger rail stations in the East Bronx and significant improvements to railroad infrastructure, Penn Station Access will support the local economy and attract regional talent by increasing accessibility to underserved neighborhoods, cutting travel times, and introducing reverse commuting opportunities.


The project will use Amtrak’s existing Hell Gate Line to access Penn Station, maximizing the potential of existing infrastructure, while minimizing impacts on the surrounding community. It will bring the Hell Gate Line into a state of good repair, improve reliability and on-time performance for intercity passengers, and prepare the line for future high-speed rail.


In addition to 4 new ADA stations, the project will turn the existing 2-track railroad into a largely 4-track railroad, with over 19 miles of new and rehabilitated track work. The project also includes 4 bridge rehabilitations, 4 new and 1 reconfigured interlockings, 5 new and 2 upgraded substations, and the modernization of signal, power and communication infrastructure. LBTC is providing electrical inspection services.
