Re-Reconfiguring.
New York City Transit Authority (NYCTA) R160A no. 9277 (Alstom, 2005-2010) is the lead motor on a Coney Island-bound F train seen rising up onto the Culver Line structure as it approaches Ditmas Ave Station. The interlocking at this location was built by the IND when they extended their four-track South Brooklyn Line and "recaptured" the three-track BMT Culver Line, which originally curved west here towards 9th Ave Station on the BMT West End Line. The interlocking is currently being reconfigured as part of the Culver CBTC project, and the five switches merging the four tracks into three will soon be only one: where the two express tracks merge into one. This work has finally begun after lengthy delays with the manufacture of the Special Work Portions (SWPs) for this project: the Manhattan-bound local track B2 has been "hard railed" and its switch removed. The operational flexibility will not be lost, though; crossovers allowing moves between the express and local tracks have been added within the tunnel, sheltering them from the elements and reducing the chance of delays due to snow in the winter.
