As Amtrak’s Acela service grew in popularity along the Northeast Corridor, the agency required specialized facilities capable of supporting the nation’s first high‑speed rail fleet. STV, as part of a design–build team, delivered comprehensive architectural and engineering design services for three new maintenance facilities located at Southampton Yard in Boston, Sunnyside Yard in Queens and Ivy City Yard in Washington, D.C. Representing more than 200,000 square feet of combined service space, these facilities were the first of their kind in the United States and established a national model for high‑speed rail maintenance.
What challenges did STV address?
Designing three state‑of‑the‑art facilities across geographically dispersed and operationally active rail yards required complex phasing, coordination and staging. Each site needed to maintain ongoing operations while integrating new service, inspection and repair capabilities suited to Acela’s sophisticated technology. The challenge included designing flexible spaces for heavy repair, inspection, storage and advanced diagnostic systems while ensuring minimal disruption to day‑to‑day yard activities.
What solutions did STV deliver?
STV designed high‑capacity facilities featuring heavy repair bays, wheel diagnostic and truing shops, maintenance workspaces, trainwashers and employee welfare areas. The team coordinated architectural, structural, mechanical, electrical, plumbing and fire protection systems across all three sites. Through strategic construction planning and phased implementation, STV ensured that existing yard operations remained active throughout the buildout.
How does this project benefit the region?
These facilities enable efficient servicing of Acela’s high‑speed fleet, improving reliability, reducing equipment downtime and supporting the expansion of high‑speed rail in the United States. The program strengthens mobility along the Northeast Corridor and advances the country’s long‑term high‑speed rail capabilities.
