The Metropolitan Transportation Authority (MTA) today announced that signal modernization work on the  ​ line will continue during the summer, with work on select weeknights and weekends beginning Monday, July 14 through Monday, August 18. The   ​train’s signal system dates back to the 1930s and is now being modernized with state-of-the-art Communications-based Train Control (CBTC), which will bring more reliable service to the 160,000 riders who take the  ​ every day. Once the $368 million project is completed, the  ​ will be the third line in the subway system to be fully converted to CBTC, following the   and the  .

Work on this signal modernization project will continue until Q3 2027. Since the   train shutdown of 2024, the MTA completed three phases of 24/7 outages for nine and a half weeks along the  ​ line to perform critical signal modernization and state-of-good-repair work. During that period, the project team successfully installed modern signal equipment across the entire line and completed critical work, including the reconstruction of the Court Square interlocking and approximately 30 miles of track. The nearly century-old signals needing replacement on the ​  line have been a frequent source of service disruptions and delays.

This is MTA Construction & Development’s first design-build signal modernization project. Innovative contracting methods such as design-build allow the MTA to contain project costs while limiting service disruption and impacts to customers.

In addition to CBTC work, NYC Transit took advantage of last year’s service outages to perform critical station upgrades, repairs, and deep cleanings at 10 subway stations along the  ​ line including: 

  • Scraping, priming and painting 233,645 square feet of platform, track and mezzanine ceiling

  • Replacing 9,495 tiles

  • Scraping, priming and painting 1,802 station columns

  • Converting 4,858 LED lamps

The project also coordinated with Boldyn Networks to facilitate the installation of 5G cellular service throughout the underground portions of the line. This service is expected to begin consumer service later this fall.

 customers have also benefitted from the roll-out of R211 trains that started in March. The new train cars, which include the R211T open-gangway trains, deliver increased reliability and customer comfort and will be compatible with the CBTC signaling technology.
