This fall, Amtrak begins deploying its new Airo trains, modernizing passenger rail travel with sleeker designs, enhanced comfort, and reduced emissions across several regions including the Pacific Northwest and the Northeast.
- Airo trains can carry 317 passengers, improving comfort and service frequency
- Trains meet EPA Tier 4 emissions standards, cutting pollution
- Deployment starts on Cascades route; Northeast riders to benefit by 2027
What happened
Amtrak is introducing 83 new trainsets named Airo, starting this fall with eight trains on the Cascades route between Seattle and Portland. These modern trains are designed to replace aging equipment, some dating back to the 1970s, and bring cleaner, more reliable service to routes in the Pacific Northwest, New England, Pennsylvania, and the mid-Atlantic region. The Airo trains are engineered to reach speeds of up to 125 mph and accommodate 317 passengers, significantly increasing capacity compared to the existing fleet.
This $8-billion upgrade follows the federal government’s historic $66 billion investment in passenger and freight rail under the Infrastructure Investment and Jobs Act. Despite political challenges to rail funding in recent years, Amtrak continues to set ridership records and has secured $3 billion recently, including $2 billion dedicated to purchasing new trains. The Airo rollout aims to reduce travel times and enhance rider experience on multiple routes while helping Amtrak meet growing demand.
Why it feels good
For passengers like Charlie Hamilton, the executive director of All Aboard Washington, riding the train offers a smoother and more scenic alternative to the often congested highway traffic along the West Coast. Faster and more frequent train service is a welcome prospect for those traveling busy corridors like Seattle to Portland, where trains take about the same time as driving yet make multiple stops. The new fleet could enable hourly departures, improving convenience and accessibility for daily and occasional travelers alike.
Beyond convenience, the Airo trains contribute meaningfully to environmental sustainability. Rail transport carries 8% of the world's passengers with only 2% of transportation energy demand. These new locomotives not only meet the highest EPA emissions standards but also feature hybrid electric and diesel propulsion, enabling cleaner operation on both electrified and conventional lines. Upgrading equipment to more efficient technology helps reduce air pollution and moves toward greener travel options for millions.
What to enjoy or watch next
The initial deployment of Airo trains on the Cascades route this fall will be closely watched as a milestone in Amtrak’s modernization efforts. Passengers can expect to experience greater comfort, reduced wait times, and a smoother journey through some of the Pacific Northwest’s most stunning landscapes. Attention will also turn to how quickly service frequency increases with the new equipment in place, potentially reshaping commuter and regional travel patterns in the area.
Looking ahead to 2027, passengers on the Northeast Regional route will benefit from Airo trainsets, particularly those traveling between Virginia and the Northeast. Improved equipment will help Amtrak streamline operations, reduce engine swaps, and shorten delays at busy hubs like Union Station in Washington, D.C. As Amtrak continues to expand this fleet, the broader U.S. rail network stands to gain from cleaner, faster, and more reliable service, supporting a positive shift toward sustainable transportation.
