Weekend Work January 4 - 7, 2013
During the January 4-7 weekend shutdown of the Line between Queensboro Plaza and Times Sq-42 St, our maintenance workers and contractors accomplished several important tasks on the work taking place on this vital transportation link between Flushing, Queens and Midtown Manhattan:
Signal System Modernization CBTC, Flushing Line
Contractor work crews performed work associated with the installation of a modern signal system on the Flushing line. When completed, this line will be equipped with a Communications Based Train Control (CBTC) system. The work over the last weekend included delivery and initial installation of wayside equipment (one junction box, one home signal, 15 third rail boots and 48 riser box covers) from Times Sq-42 St to 5 Av stations. In addition, approximately, 8,300 feet of fiber optic cable was pulled.
An abandoned two-inch air line at Times Sq-42 St was removed and installation of conduits for tunnel lighting continued. The contractor also installed cable tags, brackets, and secured cables previously pulled through manholes on the Queens-bound track from Times Sq-42 St to Grand Central-42 St.
Vernon Boulevard-Jackson Av Station
Repairs were made to the walls and ceiling at the track level and water remediation work was performed.
Additional WorkExisting ducts are being demolished on the outer wall of the Steinway Tunnel’s Queens-bound side and Manhattan-bound side. A new duct bank (a structure that houses equipment) is being built for new cables that supplies traction (third rail) power for the Line. Also, on the Queens-bound track, the contractor installed 1,200 feet of vertical rebar, drilled 500 feet of holes for rebar doweling and trimmed 800 feet of outer wall concrete sections to partially recess the duct bank in the outer wall.
