MTA New York City Transit (NYCT) crews on March 20 will begin installing a communications-based train control (CBTC) system on the F subway line between Church Avenue and Coney Island stations in Brooklyn.
The $253 million project is part of the agency’s Culver Line signal modernization project to replace the 70-year-old block signaling system on the line. CBTC enables continuous updates on train positions and speeds, which will allow for faster and more efficient operations compared with the old system, NYCT officials said in a press release.
Work also will include construction of three signal facilities at Ditmas Avenue, Bay Parkway and Avenue X stations.
Crews will build a new relay room to house the new signaling equipment, reconfigure and replace two old interlockings at Avenue X and Ditmas Avenue stations, and add two interlockings south of Church Avenue Station.
Work on the F Line will continue into 2021.
