The new Acela has been promised for the last four years. After resolving design and operation issues, Amtrak is now announcing its debut at the end of August.

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.
