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.

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.

The new trains feature 27 percent more seats and more daily departures, Amtrak said. They will have a top speed of 160 miles per hour, 10 miles per hour faster than the current fleet.
