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 D line.
From 10 p.m. until 5 a.m., service will be shut down between 205th Street and 161st Street-Yankee Stadium.
The MTA suggests riders use the No. 4 train to nearby stations.
