One Trainset, Three Testing Stages, and a Big Step Forward for Amtrak Cascades
Last edited Tue May 19, 2026, 05:07 PM - Edit history (1)
A new era for passenger rail arrived in Seattle, marking a major milestone as Amtrak moves closer to introducing a new generation of modern, accessible, and passenger‑focused train service in the region.
The first trainset represents a new generation of rail travel, designed to elevate the experience and strengthen service across the Pacific Northwest. With regionally inspired design, modern amenities, enhanced accessibility, and local food & beverage offerings, the new trains are built around the people who ride them.
Before this train (and every new trainset) can welcome customers onboard, it goes through a carefully designed journey of testing, training, and real‑world preparation.
✅ Stage 1: Putting the Train to the Test
For the first trainset in the Amtrak Cascades fleet, the journey began on a dedicated test track in Pueblo, Colorado, where teams validated core systems and made sure everything performed exactly as intended.

First Amtrak Cascades ‘Airos’ Arrive in Seattle for Testing
On Saturday just before 6:30pm, Amtrak delivered a new ‘Airo’ class trainset with five coaches and a power car to Seattle’s King Street Station for deployment on Amtrak Cascades starting this fall. The new vehicles were coupled onto Amtrak's Empire Builder service and trucked over from Chicago, the other terminus of the cross-country rail line.
Trainspotters followed the train on live-tracking maps and took photos and film of the new vehicles as they passed through the state, including Wenatchee, Snohomish County and Seattle. The real-time information was helpful as the Airo-laden Empire Builder run was heavily delayed by freight traffic in North Dakota and Montana, arriving about seven hours later than its original 11:30am scheduled arrival.
As the first of six new railcar sets, the new Airos will eventually make their way into service later this fall. Amtrak is waiting on additional trainsets to arrive and completion of staff training and route testing along the Cascades route – a 460-mile-long corridor that stretches from Vancouver, British Columbia to Eugene, Oregon.
Prior to their arrival in Seattle, the Airo railcars underwent initial testing at the federal Transportation Technology Center in Pueblo, Colorado and then on the Amtrak-owned Northeast Corridor for active track testing.
Shout out to Chase & the @amtrakcascades.wsdot.wa.gov team for getting these new Airo trains to the PNW! Can’t wait to ride!
