The Metropolitan Transportation Authority (MTA) late last week began testing a new signal room south of the Kings Highway subway station and new solid-state interlocking equipment as part of a broader modernization of the F Line in Brooklyn, New York.
The new infrastructure will allow MTA New York City Transit crews to respond faster and provide alternative service options when there are disruptions, MTA officials said in a press release.
The infrastructure work is necessary for a related project to replace 70-year-old signals between Church Avenue and Coney Island stations with a modern communications-based train control system. Combined, the projects will bring greater reliability to the entire F Line in Brooklyn, Manhattan and Queens, agency officials said.
Replacement of the Kings Highway interlocking, which governs how trains switch tracks at a key location along the F Line, and the addition of three new signal facilities at the Ditmas Avenue, Bay Parkway and Avenue X stations began in 2017.
