The San Joaquin Regional Rail Commission selected STV to oversee design of a new 64-acre facility for the repair, maintenance, cleaning, and overnight storage of locomotives and cars used in its 86-mile Altamont Commuter Express service and future passenger rail service expansions. The new 121,000-sf main building houses three overhead cranes, a wheel truing machine, a drop table, stores, employee common areas, and administrative offices.

Photovoltaic roof panels provide the added benefit of reduced grid energy consumption to the natural ventilation and lighting provided by the saw-tooth roof design. Auxiliary buildings include a 26,500-sf service and inspection canopy, a 2,600-sf oil/water separator building, and a 1,660-sf trainwash equipment building. STV also provided construction-phase engineering support for the $65 million project, which was the first of its type in the United States to earn LEED® Silver certification.
