D train service will be suspended in both directions between 205th Street and 161st Street-Yankee Stadium for four consecutive weeknights until April 12. B service ends early each night.
FASTRACK was introduced in January 2012, devoting four straight weeknights to perform maintenance work in tunnels, stations and on tracks, completely suspending service within a given line segment for a seven-hour period between. This gives free access to the system, allowing an army of maintenance workers to perform dozens of tasks without the concern of having to "clear up" to allow trains to pass.
The new FASTRACK corridors for 2013 include: the Broadway N, Q, and R south of Queensboro Plaza to Court Street; the A line between 168th Street and 207th Street in Upper Manhattan; the D Concourse Line between 161st and 205th Street and the Lexington Avenue 4, 5 and 6 local and express lines between Grand Central-42nd Street and 125th Street.
FASTRACK projects are also scheduled for the Sixth/Eighth Avenue Lines (A, B, C and D) between 59th Street-Columbus Circle and 168th Street-Broadway and 161st Street; the Fourth Avenue line (D, N and R) between 36th Street and 95th Street in Brooklyn and the 2 along Nostrand Avenue between Franklin and Flatbush Avenues.
The next FASTRACK overnight closure will be at all N, Q and R stations in Manhattan for four consecutive weeknights from April 15 to April 19.
