Draft:Amtrak Airo
Passenger train
From Wikipedia, the free encyclopedia
Amtrak Airo is a high-speed, intercity trainset built by Siemens for Amtrak. The locomotive is based on the Siemens Charger ALC-42 used by Amtrak across the country. The passenger cars are based on the Siemens Venture cars used in Amtrak Midwest and Amtrak California. The trainsets are expected to debut in 2026.[1]

Amtrak released a request for proposals in 2019, and Siemens was selected as manufacturer in 2021.[2][3]Amtrak initially ordered 73 trainsets in 2022, but the order was later increased to 83 in 2023.[4]
The trainsets will be built in three configurations, varying according to the capacity and infrastucture of the routes over which they will operate. All trainsets will include an ALC-42E Charger locomotive on one end of the consist and a cab car on the opposite end. Onboard, there will be a car with a food service area and a mix of Coach Class and Business Class seating.
As preparation for the Airo trainsets, Amtrak began construction of new maintainence facilities in major cities.[5]
Types
There will be 26 six-car catenary-diesel dual-power trainsets that will include an Auxiliary Power Vehicle (APV). The APV will be the trailer car closest to the locomotive and will include a pantograph, an underfloor transformer to handle the Northeast Corridor's 25 kV, 12.5 kV and 12 kV AC traction power systems, a four-quadrant chopper, and two powered trucks. In electrified territory, the APV will draw power from overhead lines, through the transformer and fed to the four traction motors in the car, and via a DC link cable, to the four traction motors in the locomotive. These trainsets will be used on the Carolinian, Downeaster, Hartford Line, Keystone Service, Palmetto, Pennsylvanian, Valley Flyer and Vermonter.
32 trainsets will be eight-car catenary-diesel dual-power trainsets, similarly configured, for use on Northeast Regional trains, including through trains to Virginia and Springfield, Massachusetts.
8 trainsets will be six-car diesel only trainsets, similarly configured, for use in Amtrak Cascades, as this route does not have electric catenary systems.
17 trainsets will be six-car battery-diesel hybrid trainsets, where the trailer car closest to the locomotive will have batteries to supply electricity to traction motors in the locomotive when operating around New York Penn Station, eliminating the need for third rail propulsion on the Adirondack, Empire Service, Ethan Allen Express, and Maple Leaf.
In March 2025, 83 coach cars and 9 locomotives have been completed, with 23 coaches in final assembly stages. In July 2025, the first trainset was completed and sent to Pueblo,CO for testing.[6][7] In October 2025, the trainset passed testing in Pueblo and is currently undergoing additional testing on the Northeast Corridor.[8]
