The Arch Street Yard and Shop facility is an intergral part of the East Side Access Project, which will provide LIRR service to Grand Central Station by the year 2007. The primary purpose of this facility is to service, maintain, and store new "M7" trains that will be used for the new service. This fast track design-build project involved the construction of a five-track heavy repair maintenance facility with state-of-the-art industrial equipment such as wheel truing machines, train lift systems, train turntables, bridge cranes, monorail cranes and custom lift systems.

The scope of work also involved construction of a complete underground utility network throughout the five-acre site that services traction power, building power, drainage, sanitary and communication systems. The project team installed almost four miles of track equipped with many turnouts, switches and third rail. In addition to the Maintenance Shop Facility, the Arch Street Project included the construction of other support yard facilities such as a new Traction Power Substation, 1000' long EIC platform, Engineering Support Building, and EIC Support Building Structures. One of the more challenging aspects of the project was to perform all the work in and around an active freight rail yard operated by the New York and Atlantic Railway. This project is one of two major East Side Access Projects that were awarded to Skanska USA Civil by the MTA.
