Amtrak has officially opened a new 100,000-square-foot maintenance facility in Seattle's SODO neighborhood. The site is part of a larger $300 million expansion project and was completed ahead of its initial 2027 target.
Why it matters
The new facility provides indoor maintenance capabilities to protect trains and workers from Pacific Northwest weather. By consolidating maintenance in one location, Amtrak expects to boost worker productivity and eliminate the need to split up trains.
The new 600-foot-long building features pilings driven 140 feet into the ground. During construction, crews successfully removed 500,000 gallons of water daily to stabilize the site.
