MTA New York City Transit (NYCT) is continuing work on a project to replace tracks and an aging fixed-block signal system on the Flushing Line, which carries 7 Line trains.

The agency is replacing both underground and elevated tracks and installing new signals for a communications-based train control (CBTC) system, agency officials said in a press release.

The CBTC system is expected to increase operational flexibility and allow additional trains to run consistently on the line.

"A safe, reliable Flushing Line is critical to the growth of Queens and these projects are critical to the future of the line," said NYCT Acting President Darryl Irick. "Replacing old tracks means a smoother, faster ride for customers, and installing a modern signal system means less crowded and more reliable commutes."

RailWorks Corp. subsidiary L.K. Comstock & Co. Inc. is installing the CBTC system on the Flushing Line.

The track replacement and new signal system are part of NYCT's $774 million worth of improvements on the line.

In April 2016, the agency completed reconstruction and fortification of the line's Steinway Tunnel, which was damaged during Hurricane Sandy in 2012.

The completion of that project marked a milestone in efforts to overhaul the Flushing Line, according to the agency. The project also will be "critical" in reducing planned and emergency service suspensions between Manhattan and Queens, NYCT officials said.
