Amtrak said that the Avelia Liberty trainsets would allow for improved frequency and greater capacity on the ''Acela'' service. The 28 trainsets ordered (compared to the 20 older trainsets) would allow for more frequent service on the route, including half-hourly peak service between New York City and Washington, D.C. Each of the new trainsets will also have 378 seats and 8 wheelchair locations for a total capacity of 386 passengers (25% more than the current trainsets), allowing for greater passenger capacity.
U.S. assembly of the trainsets is taking place at Alstom's plants in

. The trainsets will be equipped with an
active tilt system, dubbed Tiltronix by Alstom and based on Pendolinos, that will allow higher speeds on curved portions of the corridor track at a maximum tilt angle of 6.3°.
Each Avelia Liberty trainset has power cars at each end of the train, and (initially) nine articulated passenger cars. An additional three passenger cars can be added if demand grows. The power cars include a Crash Energy Management system to help meet
Federal Railroad Administration (FRA) Tier-III standards while allowing a 30% reduction in train weight.
These trains will also have
