IAM-built Acela NextGen high-speed trains have started regular service on Amtrak’s Northeast Corridor, following months of testing. These new Avelia Liberty trainsets are capable of speeds up to 160 miles per hour and represent a significant technological upgrade over the existing fleet.
The locomotives feature 9,400 horsepower, compared to the 6,100 horsepower Acela Express models that have been in operation since 2000. Members of IAM Local 2741 (District 19) based in Hornell, New York, are responsible for building these trainsets.
“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 features such as 5G Wi-Fi connectivity, individual USB ports at seats for device charging, power outlets, and reading lights built into headrests. There are also changes to seating arrangements and expanded dining and kitchen areas aimed at improving comfort for travelers. The TCU/IAM union is part of Amtrak’s On-board Service Workers Council which contributes input on customer experience.
“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 sets will operate alongside current Acela Express units. The new fleet operates multiple daily trips across a route spanning fourteen stations from Washington D.C.’s Union Station through Boston South Station.
