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

The “NextGen Acela” is a key part of Amtrak’s plan to broadly modernize its fleet. This plan also includes the new “Amtrak Airo” trains to come to routes along the East Coast, more efficient long distance traveling and upgraded train interiors.

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.
