Amtrak Introduces Airo Trainsets on the Cascades Corridor
By Drooid · · How we work
Launch of Next-Generation Railcars
Late September 2026 marks the debut of Amtrak’s Airo trainsets on the Amtrak Cascades corridor, the first U.S. route to receive the new fleet. Two trainsets will begin operating four daily round-trips, linking Seattle with Vancouver, B.C., and Eugene, Oregon. The rollout will continue through early 2027, ultimately replacing the older Horizon cars that have run at reduced capacity since 2025.
Background & Context
In 2021, Amtrak ordered eight Siemens-built Airo trainsets as part of a nationwide modernization campaign. The Horizon rail cars, many dating to the 1970s, were withdrawn in 2025 after corrosion issues were discovered, prompting a decline in available seats. The Cascades line, which serves eighteen cities from Vancouver to Eugene, is the first to receive the next-generation equipment, with the Northeast Regional slated for the next phase.
Key Features & Capacity
Each Airo trainset provides more than 300 ergonomically designed seats, panoramic windows, complimentary Wi-Fi, individual power outlets, and digital information displays. Accessibility improvements include automated steps, enhanced wayfinding, and six touch-less restrooms. The onboard café will offer region-inspired food and beverage options. Compared with the legacy coaches, the new cars add a significant number of seats per departure, addressing chronic overcrowding on Fridays and Sundays.
Official Statements & Responses
Amtrak Interim President Byl Herrmann described the launch as “an important milestone” for the Cascades and for Amtrak’s broader modernization effort. Julie Meredith, Washington State Department of Transportation Secretary, called the trains “a game-changer” that bring “improved reliability, comfort, and amenities” to one of the nation’s most scenic rail corridors. Chris Warner, interim director of the Oregon Department of Transportation, highlighted Oregon’s record ridership and the partnership with Amtrak to expand service. “When the first Airo trainsets welcome passengers later this month, it will mark the start of a journey that extends far beyond the Pacific Northwest,” — Tobias Bauer, CEO of Siemens Mobility North America.
On-the-Ground Reports
“That has been what has kept us from moving forward,” — Charles Hamilton, executive director of All Aboard Washington. “This will give us more capacity to have more folks riding,” — Charles Hamilton. Observers noted that while the trains feature modern interiors and larger windows, the corridor’s freight-dominated tracks limit top speeds to 79 mph, meaning travel times will not improve.
Conflicting Reports & Gaps
Sources agree that the Airo cars increase seat capacity, yet they also note that the existing timetable will remain unchanged, and the freight-owned right-of-way constrains speed and frequency. No definitive schedule for additional round-trips or higher-speed service has been announced, and funding for the required track upgrades remains uncertain. While ridership reached a near-million-rider peak in 2024, statistics for 2025 show a decline, reflecting the reduced capacity after the Horizon cars were withdrawn.
Verbatim Quotes
- “These new Amtrak Cascades trains are a game-changer for rail travel in the Pacific Northwest,” — Washington State Department
- “Oregon continues to reach record train ridership, and we are proud to partner with Amtrak to bring their new trains to the Pacific Northwest.” — Chris Warner, transportation interim director
What’s Next
Amtrak plans to introduce the remaining six Airo trainsets on the Cascades line by early 2027, followed by deployment on the Northeast Regional corridor. Washington and Oregon transportation departments are drafting a long-range service development plan that could involve track improvements, siding extensions, and signal upgrades—projects that would require substantial federal and state funding. A new $300 million maintenance facility near downtown Seattle is nearing completion to service the larger Airo cars.
