Siemens Airo Trains Launch on Amtrak Cascades, Boosting Pacific Northwest Capacity

Key points

• The Airo trains, manufactured by Siemens, will debut on Amtrak Cascades on September 30, 2026, with two trainsets initially operating four daily trips.
• The trains feature 317 seats, ergonomic seating, USB-C chargers, improved Wi-Fi, and advanced monitoring systems to reduce downtime.
• The full rollout of eight Airo trainsets is expected by early 2027, replacing older Amfleet and Talgo trainsets.
• Speed on the Pacific Northwest routes remains limited to 79 mph due to existing rail infrastructure, though the trains can reach 125 mph on the Northeast Corridor.
• The Airo trains are part of a broader Amtrak fleet replacement program, with 83 new trains ordered nationwide, funded by the Biden-era Infrastructure Investment and Jobs Act.

Background

The Amtrak Cascades route, which has operated since 1994, has seen record ridership, with over 1 million passengers annually. The introduction of the Airo trains follows a period of fleet modernization, including the removal of 26 cars in March 2025 due to corrosion. The new trains are part of a larger effort to improve reliability and capacity, with Washington State aiming to increase on-time performance to 88% by 2035.

How outlets are covering it

The Urbanist emphasizes the improved passenger experience, including ergonomic seats, upgraded Wi-Fi, and a modernized cafe car, while noting that speed remains limited to 79 mph. OPB highlights the advanced monitoring systems that will reduce vehicle downtime and travel delays, as well as the broader fleet replacement program. Lookout Eugene-Springfield focuses on the modern amenities and the gradual rollout of the trains, noting that the Pacific Northwest will be the first region to receive the Airo fleet. All sources agree on the significance of the Airo trains for the region, but differ in their emphasis on technical upgrades versus passenger experience.

Why it matters

The introduction of the Airo trains marks a significant step in modernizing Amtrak's fleet and improving the passenger experience in the Pacific Northwest. The increased capacity and advanced monitoring systems are expected to reduce delays and improve reliability, addressing long-standing issues with the older trainsets. The rollout also signals a broader commitment to passenger rail, with the Trump Administration and state officials highlighting the importance of rail travel in the region.

What to watch

The full rollout of eight Airo trainsets is expected by early 2027, with additional trains entering service every three to four weeks. The trains will eventually replace all older trainsets on the Cascades route, and Amtrak plans to deploy additional Airo trains on the Northeast Corridor by late 2027. Washington State aims to increase on-time performance to 88% by 2035, though challenges remain in securing infrastructure upgrades and managing BNSF railway operations.
