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 and R Fourth Avenue lines.
From 10 p.m. until 5 a.m., N trains will be rerouted on the D line between 36th Street and Coney Island-Stillwell Avenue. Service on the r line will end each night at its regularly scheduled time.
