The Metropolitan Transportation Authority (MTA) has begun preparatory work on the next phase of the Culver (F) Line Signal Modernization project in Southern Brooklyn. The $253 million project, which had its original late March start date pushed back in the aftermath of the COVID-19 outbreak, will replace 70-year-old technology between Church Ave. and Coney Island with a Communications Based Train Control (CBTC) system.

In addition to installing CBTC along the F line, the signal modernization project will also replace the Kings Highway Interlocking as well as signal facilities at Ditmas Av, Bay Parkway and Avenue X with new SSI (solid-state interlocking) equipment. Scope of work includes building a new relay room to house the new signaling equipment, reconfiguring and replacing the Avenue X and Ditmas Ave. interlockings, and adding two new interlockings south of Church Ave.

Siemens and Thales are providing the CBTC system on the entire Culver Line project, following a successful interoperability demonstration on the Culver Line test track.

Work on the F line will continue in 2021 and 2022, with the CBTC phase beginning immediately following the conclusion of the interlocking work on July 27 and continuing during most weekends through the end of the year.
