Panel Replacement.
New York City Transit Authority (NYCTA) R77 locomotive no. 885 (GE SL50, 1983) pauses with its train at Lorimer St station on the BMT Jamaica Line, as one of the two trains working a track panel replacement job here. These jobs typically use two work trains: one to move old panels to a location where they can be lifted down to the street below, and one moving new panels into position for installation.
