Line Weekend Work November 8-11, 2013
In order to give subway repair crews and a contractor a significant period of time to work on critical maintenance and construction projects, service on the line was suspended between Queensboro Plaza and Times Sq-42 St during the weekend of November 8-11. When these tasks are completed, Flushing Line customers will benefit from improved service reliability, increased customer comfort and enhanced customer communications. The line is 9.4-miles long, has 21 stations and connects Downtown Flushing, Queens and Midtown Manhattan.
The weekend work included the ongoing installation of a modern signal system, replacing track on the elevated structure in Long Island City, and infrastructure and electrical improvement work in the under river tunnel between Queens and Manhattan.
Communications-Based Train Control
CBTC installation was completed on the Times Square interlocking. An interlocking is the arrangement of signals and switches that allow trains to move from one track to another.
Capital Track Program
As part of the Capital Track Program, work crews cut cross ties on the Main St-bound track at the Queensboro Plaza Station and scraped and cleaned the track bed.
Work continued in the Steinway Tunnel, which links Queens and Manhattan. Contractors poured concrete for the (new) “duct bank” which will house electrical cables to supply third-rail power. Repairs were made to the duct bank along the Queens-bound track-1,100 feet of the outer wall and 1,660 feet of the inner wall. In addition, workers pulled 1,510 feet of control cable and 1,360 feet of MCM electrical cable, raised the floor and installed two floor drains in two manholes and installed covers and hanging doors on four manholes on the Queens-bound track. Damaged concrete on the Queens-bound track was also repaired.
