WASHINGTON — Amtrak has introduced its long-awaited NextGen Acela service between Washington and New York, with the first new trainsets departing today (Aug. 27, 2025) from Washington at 5 a.m. and Boston at 6 a.m. ET on trips for invited guests. Service for the general public begins Thursday, Aug. 28.
The first of what will eventually be 28 Alstom-built trainsets will debut with two round trips Sunday through Friday and a single round trip on Saturdays. Introduction of the new equipment will continue into 2027.
“These trains are beautiful, they are fast, they are state of the art, and they are American made,” Amtrak President Roger Harris said at a Washington press conference. “And best of all, beginning tomorrow, they are ready for service.”

The new equipment includes 27% more seating than the first-generation Acelas, and the 28-train fleet will allow a 40% increase in Acela service. Built in Hornell, N.Y., they are based on the Alstom’s Avelia; more than 1,000 trainsets have been sold in 25 countries. Alstom says their active-tilt system allows speeds up to 30% than conventional high-speed equipment.
“From the moment our guests step onboard, they’ll feel the difference of a NextGen Acela train thanks to a more modern, premium, and elevated experience,” Tony Coscia, Amtrak board chair, said in a press release.


Transportation Secretary Sean Duffy said at the press conference that the new trains will provide “a better experience for the riding public.
“I would love to see high speed rail in America,” Duffy said. “… This is, at 160 mph, one great step in that process.”
Alstom CEO Henri Poupart-Lafarge said in a press release, “The NextGen Acela trains are the first high-speed trains built in America. The team at Alstom has brought nearly five decades of global experience in high-speed rail to the United States to deliver the fastest and most technologically advanced trains in the nation.” Michael Keroullé, president of Alstom Americas, called the trains’ debut “a pivotal moment for American rail.
“These trains, built by skilled American workers in Hornell, are not just about speed,” Keroullé said. “They symbolize our dedication to bringing the world’s best rail technology to the United States and supporting economic growth across the nation.”

The trains’ debut comes just over nine years after Amtrak and Alstom announced plans for the new equipment [see “Almtrak, Alstom reach $2.45 billion deal,” Trains.com, Aug. 16, 2016], and four years after they were initially projected to enter operation. Known difficulties that led to the delays include issues with the trains’ pantographs, which initially would sometimes lose contact with the catenary wire; pandemic-related difficulties; wheelset issues; and problems with computer modeling of the trains’ performance, a required step in the certification process. The delay forced Amtrak to extend the use of the first-generation Acelas, introduced in 2000, beyond their intended lifespan, a process that led to increasing reliability issues and saw four trainsets cannibalized for parts.
The new equipment is initially scheduled to run on weekday trains Nos. 2153, 2154, 2170, and 2173; Saturday trains 2250 and 2251, and Sunday trains 2248, 2258, 2259, and 2271. A “NextGen” icon identifies those trains on Amtrak booking platforms.
