State-of-the-art Acela high-speed trains built by members of the International Association of Machinists and Aerospace Workers (IAM) have started regular service on Amtrak’s Northeast Rail Corridor. These new NextGen Acela trainsets, constructed in Hornell, New York by IAM Local 2741 (District 19), follow months of testing and can reach speeds up to 160 miles per hour.
The Avelia Liberty trains feature a significant boost in power, offering 9,400 horsepower compared to the 6,100 horsepower of the original Acela Express locomotives that have been in operation since 2000. The introduction of these trainsets marks an advancement for high-speed rail manufacturing within the United States.
“Amtrak had an all-time ridership record of 32.9 million passengers in Fiscal Year 2024. That milestone would not be possible without our members’ expertise and unwavering commitment to maintaining safety and excellent customer service,” said TCU/IAM President Artie Maratea. “These new trainsets meet our riders’ demands, and we are excited to serve our customers with this service”.
The updated passenger cars include modern features such as 5G Wi-Fi, USB ports at each seat for charging devices, accessible power outlets, and reading lights integrated into headrests. Seating arrangements as well as dining and kitchen spaces have also been redesigned for greater comfort. TCU/IAM is part of Amtrak’s On-board Service Workers Council, which helps represent worker perspectives on customer experience improvements.
“High-speed rail is here. Now we build out the railways and infrastructure to support even faster passenger trains in the United States,” said Josh Hartford, Special Assistant to the IAM President for Rail Division. “District 19 and IAM Rail Division members can do the job to make America’s rail transportation world-class.”
A total of 28 NextGen Acela trains will enter service between now and 2027. Initially, five trainsets will operate alongside the current Acela Express fleet. The Avelia Liberty cars are equipped with a tilt system designed for smoother rides. These trains will make several trips daily along a route that connects Washington D.C.’s Union Station with Boston South Station over fourteen stops.
