Rails Being Delivered for the 7 Extension

The 7 Subway Extension Project, now 65 percent complete, has just received its first set of rails.

Each rail delivered to the extension site is 390 feet in length and weighs approximately 15,000 pounds. Each delivery consists of only four rails because of their weight. The rails are delivered with a work train leaving the Linden Shop in Brooklyn. The trip takes about 48 hours from loading to unloading because it only travels during the midnight shift in order to avoid interrupting passenger service.

The first of sixteen deliveries left the Linden Shop on April 30 headed for the Grand Concourse Yard (via the 4 Subway line) where it laid up for the day. The next day, the work train traveled via the D Subway line and south of 34th Street, switched tracks and came back north on the F Subway line. From there, it crossed over at Queens Plaza to the N Subway line, and then switched to the 7 Subway line to Times Square.

As for the overall project, structural work at the future 34th Street Station is now complete. Work also began in September on the project's last major contract. This systems contract includes rail track, all mechanical, electrical and related systems throughout the tunnels, station, ventilation buildings and the main subway entrance at 34th Street. Completion of this contract is the last piece needed to initiate service on the 7 Subway Extension.
