The No. 4, 5 and 6 trains will change service this week as part of the MTA's FASTRACK repair program.

From 10 p.m. to 5 a.m. Monday night through Friday morning, service on those lines will express in both directions between 125th Street and Grand Central. Crews will repair signals, rails and station fixtures.

Trains will skip seven local stations, but stop at 59th Street and 86th Street. As an alternative, straphangers can take M101 Limited buses running uptown on Third Avenue and downtown on Lexington Avenue.

The No. 5 train, which stops running during late-night hours, will suspend service earlier than normal, as well as run in the Bronx between Dyre Avenue and East 180th Street all night. To get to Manhattan from the Bronx, riders on the No. 5 trains can transfer to the No. 2 train at East 180th Street and 149 Street and Grand Concourse.
