For four straight weeknights this week, approximately 700 MTA New York City Transit workers are performing more than 300 maintenance tasks in stations and tunnels along a segment of the Lexington Avenue 4, 5, and 6 line stretching between Grand Central-42nd Street and Atlantic Avenue in Brooklyn. Service will be suspended in both directions between 10 p.m. and 5 a.m.

Workers are performing a variety of tasks that can be accomplished much more safely and efficiently in the absence of train service. Maintenance workers will take this opportunity to inspect track, repair or replace track components, and perform power and signal inspection and maintenance tasks. Maintenance of way crews will also clean and scrape dried mud from the roadbed, which will help ensure signal reliability.

In stations, we will also be able to do spot painting, repair platform edges, wall tiles and lighting in addition to performing power washing at some of the closed stations. By shutting down a section of a subway line, we can work more efficiently and at less cost, in many cases taking days to complete tasks that would normally take weeks.

"All of this is work that must be done to maintain the safe, smooth and efficient operation of a subway system that runs around the clock, seven days a week. However, by suspending service along line segments, workers can work on and near the tracks without having to interrupt that work every few minutes while a train moves through the area," said NYC Transit President Thomas F. Prendergast.

Fifteen stations on the 4/5/6 line will be closed to entry from 10 p.m. until 5 a.m. Uptown 4/5/6 service will be available at Grand Central-42nd-Street. Substantial alternate service is available via parallel subway corridors, though riders are advised to allow extra time for their trips.

Work will proceed along 6.7 route miles of subway, which translates to nearly 20 miles of track.

Our next FASTRACK overnight closure will be on the Seventh Avenue 1/2/3 line between 34th Street and Atlantic Avenue from 10 p.m. to 5 a.m. for four consecutive nights beginning Monday, February 13 and ending at 5 a.m. Friday, February 17.

When a line segment is closed at night, customers can expect to add 20 minutes to their usual travel time. Alternative transportation options will be detailed in announcements and posters on trains, in stations and on selected buses; brochures will be available in both English and Spanish.

Information will also be available through social media, email and text alerts.
