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 2, 3 and 4 lines.
From 10 p.m. until 5 a.m., trains will run express between Atlantic Avenue-Barclays Center and Franklin Avenue in Crown Heights. No. 3 line icon service ends early between Chambers Street and New Lots Avenue.
