Amtrak's first NextGen Acela trains officially enter service this month along the Northeast Corridor, marking the first major overhaul of the high-speed route since Acela debuted in 2000.

Amtrak's new high-speed NextGen Acela trains will soon begin operating between Boston, New York and Washington, D.C.

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.
