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.

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

The NextGen Acela fleet will boast new amenities and a smoother, faster ride, reaching top speeds of 160 mph — 10 mph faster than the old system's max. The first five trains will hit the tracks Thursday, Aug. 28, but Amtrak plans to add 28 new vehicles over the next two years.
