The FASTRACK maintenance program completely suspends train service over a segment of a subway line to give workers uninterrupted access to tracks, signals, cables, lighting, third rail components and platform edges.
The 4 and 6 trains will run local from Grand Central Station to 125th Street. No. 5 trains will stop running early.
The work will begin at 10 p.m. and last until 5 a.m. through Friday.
