“NextGen Acela is more than a new train—it’s an evolution of travel,” said Amtrak President Roger Harris. “In just a few weeks, history will be made with the debut of NextGen Acela as we launch a new standard for American train travel.”

Amtrak announced its new Acela trains will begin revenue service on Aug. 28, with all 28 of the new sets expected to be carrying passengers by the end of 2027.

Amtrak first introduced its Acela product in 2000. The NextGen trains were outlooked to enter service in 2022, but experienced numerous hurdles delaying their introduction.
