The facility, delivered on time and $50 million under budget according to Amtrak, allows a full trainset to be maintained together, replacing the separate handling of individual railcars at the existing site.

Amtrak and partners have opened a new $250 million Maintenance and Inspection Facility in Seattle, designed to support the Airo fleet that debuted on the Amtrak Cascades route last month.
Amtrak said the project was delivered on time and $50 million under budget. The facility will open in phases through the end of 2026.
Full trainset maintenance under one roof
The nearly 100,000-square-foot building is the first maintenance facility of its kind for Amtrak. It has three tracks for inspecting, servicing and performing heavy maintenance on a full trainset, all under one roof. At approximately 700 feet long, the building can accommodate an entire Amtrak Cascades Airo trainset.
Amtrak said this enables more modern and efficient maintenance. Its legacy fleet of individual railcars must be moved in and out separately at the existing facility on site, which the operator described as a time-consuming and burdensome process.
Equipment includes a drop table and split rail system, overhead bridge crane, monorail crane, sanding system and diesel, alongside wayside water and air hose reels, sanitary and vacuum waste hoses, head-end power cabinets and a fall protection lifeline system. The wider project also includes a new two-level, 39,000-square-foot parking deck for employees and material storage.
Amtrak Executive Vice President of Capital Delivery Laura Mason said: “This new facility represents a major step forward for Amtrak and our customers in the Pacific Northwest. By providing our teams the modern tools and space to maintain an entire Airo trainset at once, we can work more efficiently while continuing our commitment to safe, reliable and comfortable service for the next generation of Amtrak Cascades customers.”
Amtrak’s Seattle maintenance facility is the first of six new major facilities to support these state-of-the-art trains and mark a new era of passenger rail for the nation.”
Part of a wider fleet and facilities programme
Seattle forms part of Amtrak’s broader investment in new and upgraded maintenance facilities across the country to support today’s fleet and the next generation of trains. Amtrak said facilities of this kind allow full trainsets to be inspected and serviced together, helping reduce downtime, improve efficiency and keep trains ready for customers.
Rail Passengers Association President and CEO Jim Mathews said: “Amtrak’s Seattle maintenance facility is the first of six new major facilities to support these state-of-the-art trains and mark a new era of passenger rail for the nation.”
Washington State Department of Transportation (WSDOT) Senior Director of External Relations Allison Krutsinger said the facility, together with eight new trains and two new locomotives, represents a half-billion-dollar investment in passenger rail service for the Pacific Northwest.
Kathy Holmes, Intercity Passenger Rail Program Manager at the Oregon Department of Transportation (ODOT), said Oregon set an all-time September ridership record and that the investment will help Amtrak Cascades continue to deliver safe and reliable service across the region.
More than 40 subcontractors supported construction, many based in the Pacific Northwest, helping to create approximately 120 construction jobs. The project used 4,000 linear feet of rail, 16,000 cubic yards of concrete, 2.4 million pounds of concrete reinforcement and 12 million pounds of structural steel.
The facility continues Amtrak’s long-term investment in the Seattle Rail Yard, following earlier maintenance facility improvements, new administrative building space and a car wash completed in 2013, 2019 and 2025.
