A $368 million contract will modernize the signal system by installing CBTC (communications-based train control). The G line will be the third line in NYC equipped with the new technology–it was installed on the L line in 2009 and on the 7 line in 2019.
Both the L and 7 lines have experienced an increase in on-time performance since becoming CBTC-equipped.
The CBTC signal systems are a modern take on technology that dates back to the opening of the subway over 117 years ago. The system helps to safely run trains faster and closer together, which results in more reliable service for subway-goers. It also helps rides to run smoother.
Other lines on track to receive the CBTC signal system are:
- The F line between Church Ave. and West 8 St. in Coney Island
- The A, C, and E lines on 8th Ave.
- The E, F, M, and R lines on the Queens Blvd. Line
According to amNY the work is expected be finish in just around five years.
