IRT Dyre Avenue Line - Extent and Service

Extent and Service

It is served by the 5 train, which makes all stops.

The line is double-track, with center "express" tracks between Eastchester – Dyre Avenue and Baychester Avenue, and from Pelham Parkway to just south of Morris Park Avenue.

In the late 1990s the southbound express track was extended from south of Dyre Avenue and connected to the stub end track at Pelham Parkway for testing new subway cars for the A division. The southbound track at Dyre Avenue is in the position of the southbound express track, as the southbound local track is no longer present. The current platform is built over the northbound express track. Small portions of the original side platforms remain on both sides of Dyre Avenue station. South of Dyre Avenue station, the southbound track moves over to the local position and the southbound express track begins.

The northbound express track, now a stub end track at Pelham Parkway, has been used for storage but this use has largely been made redundant by the expansion of Unionport Yard. A small portion of this track also exists between Baychester and Dyre Avenue stations.

The north end of the line is a simple two-track stub, with crossover tracks south of Dyre Avenue terminal. The south end is a flying junction (the Dyre Avenue Flyover), into the local tracks of the IRT White Plains Road Line (with crossovers to the express track).
