After the passage of a massive state transportation bond allocated funding to overhaul elements of New York’s overcrowded passenger rail network, a new maintenance facility on the West Side of Manhattan was prioritized to support the Long Island Rail Road (LIRR). To meet that need, the John D. Caemmerer West Side Storage, conveniently located adjacent to Pennsylvania Station, was designed by the firm and can store up to 320 commuter cars. STV performed an initial feasibility study to determine the optimum location and layout, along with potential environmental impacts. The firm then provided complete design services, which included a number of complex tasks considering the size and scope of LIRR’s expansion plans and the site’s proximity to existing transportation infrastructure. 
Four tracks from Penn Station fan out to 31 tracks within the yard. These storage tracks are capable of holding five miles worth of electric equipment at one time. At the southeast corner of the yard is a six-track maintenance shop, which allows LIRR vehicles to be inspected and serviced without having to be shuttled to Long Island. To support the movement of vehicles with the yard, STV also provided complete architectural and engineering design and construction inspection services for LIRR’s control center. Adjacent to the control center is a large electric substation that was at one point, the largest direct current power substation in the world.
The North Access Connection Tunnel, a 1,500-foot-long concrete box, was constructed under the site for future routing of Albany-bound Amtrak trains into Penn Station. The firm designed and supervised the construction of this structure.
