7 line icon Line Weekend Work March 29 – 31, 2014

While service was suspended on the 7 line icon Line for the weekend, MTA New York City Transit continued the installation of a new CBTC signal system, repair and replacement of track and other infrastructure, and restoration of the Steinway Tubes.

CBTC Signal System Modernization

Workers installed conduits and other components, pulled cable into signal cases, and patched signal locations.

Track Replacement and Infrastructure

Despite difficult weather conditions, track construction installed new track at the Queensboro Plaza station and performed additional work on the 280 feet of track that was installed on previous weekends.  This included emergency protection rail, fiberglass walkway, and baskets.

Third Rail Operations upgraded 889 feet of fiberglass post brackets and third rail protection board near the Grand Central-42 St station, replacing a total of 108 brackets.

In-house forces installed 116 new track tie plates and friction pads near the 5 Av station.

Steinway Tubes

Track repair involved the removal of 50 water-damaged ties, replacing them with new composite rail ties.

Waterproofing work included installing 1,500 feet of new eight-inch discharge line and 850 feet of brackets, while workers continued injecting grout.

As part of the duct rebuilding and DC traction power negative cable monitoring system project, 300 feet of ceiling brackets and 1,900 feet of negative track feeder cable was installed.

2014 7 line icon Line Weekend Work

In 2014, MTA New York City Transit is moving forward with three major capital improvement projects on the 7 line icon Line in Queens.  When these projects are completed, customers will benefit from improved service reliability, safety, and more dependable subway service along the 9.4-mile, 21-station line connecting Downtown Flushing, Queens, with Midtown Manhattan.
