After a summer-long shutdown, the G train is back. Tuesday marked the first morning of full service on the G train since the end of June, ending a nine-week partial closure of the 11.4-mile line. During the shutdown, the Metropolitan Transportation Authority replaced 1930s-era signal infrastructure with communications-based train control (CBTC), allowing trains to run closer together, improving the reliability and efficiency of the line.
Since the shutdown began on June 28, the MTA installed modern signal equipment across the entire line and completed state-of-good repair work, including the reconstruction of the Court Square interlocking and approximately 30 miles of track, according to the MTA.
During the partial shutdown, the agency also performed “Re-NEW-vation” upgrades, repairs, and cleanings at 10 subway stations along the G line.
“Projects like these to upgrade signals and modernize the subway system ensure customers will have more dependable service for many years to come,” NYC Transit Interim President Demetrius Crichlow said. “I want to thank ​ train riders for their patience this summer and also credit ​ train czar Hugo Zamora and his team for their work ensuring customers had the smoothest possible experience during these outages.”
Fully modernizing signals on this line will continue through 2027, with work scheduled for weeknights and weekends starting later this month.
The G train provides a critical connection between Brooklyn and Queens, as well as northern and southern Brooklyn. The line has been prioritized for upgrades by the MTA because of its below-average performance.
As 6sqft previously reported, the G line’s Customer Journey Time Performance (CJTP), the estimated percentage of rider trips completed within 5 minutes of their scheduled time, was among the lowest in the system at 81.8% last November. The L train, which shut down for a year starting in 2019 and has an updated signal system, saw a CJTP of 91.4% during the same time period.
