During this weekend's shutdown between Queensboro Plaza and Times Sq-42 St, our maintenance workers and contractors accomplished several tasks as part of work taking place on the Line:

The contractor performed work associated with modernizing the signal system on the Flushing line. This line will be equipped with a modern Communications Based Train Control (CBTC) system. The work over the last weekend included installation of equipment along the subway line, pulling 47,770 feet of fiber optic and line cables, installing a cable tray and negative track conduits.

Queensboro Plaza Capital Track Program

On the Manhattan-bound track just past the Queensboro Plaza station, Division of Track personnel replaced six crossties, four third rail crossties, 35 pieces of wood slatting, 30 tie plates, and ten elevation blocks. Workers also regauged 50 feet of track at three locations and delivered garbage housing units via work trains to the Manhattan-bound and Main Street-bound platforms at Court Sq station. Just before Queensboro Plaza on the Manhattan-bound track, crews replaced 12 sections of track and 60 tie plates and cleaned the track at Queensboro Plaza.
