A slate of service changes is coming to seven subway lines for 10 weeks this summer to accommodate track replacements and signal upgrades in Manhattan and Brooklyn, the Metropolitan Transportation Authority announced on June 4.
“These improvements will allow us to deliver smoother rides and reliable service for subway riders,” said Demetrius Crichlow, executive Vice President for subways at New York City Transit. “NYC Transit remains laser-focused on welcoming New Yorkers back to a modernized system that is the quickest way to navigate the city.”
The MTA will replace the downtown express track for the 6th Avenue Line, which runs the B, D, F, and M trains, at 47-50 Sts-Rockefeller Center.
On the 8th Avenue Line, which is home to the A, C, and E trains, the transit agency will do work to prepare for major signaling upgrades between 59 St-Columbus Circle in Manhattan and High St in Brooklyn.
The work will be on weeknights for 10 weeks from June 14 through Aug. 20, when the D and F trains swap routes in Brooklyn from 9:45 pm–5 am.
On weekends, Friday through Monday morning from July 2 through Aug. 2, service will change on the D, F, A, C, and E lines (for more information see below).
The reason for the works on the 6th Avenue Line is due to an old track at the end of its useful life which needs to be replaced.
On the 8th Avenue Line, the work will include installing new axle counter technology and track switch checks to gauge the health of switch machine movement and remotely report potential failures.
Once that work is completed the MTA will install the so-called Communications-Based Train Control (CBTC) between 59 St-Columbus Circle in Manhattan and High St in Brooklyn.
CBTC replaces the aging system’s signals, some of which date back to the 1930s. The technology allows computers to drive the trains and enables subways to operate closer together and at faster speeds.
So far the MTA has installed that technology on the L and 7 lines.
Here are the full service changes:
