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.
This week, work is being done on the N, Q and R lines.
From 10 p.m. until 5 a.m., there will be no N service in Manhattan. Q trains will run on the D line in Manhattan, while R service will end early in Manhattan and Queens.
