Amtrak's newest and fastest train, the Avelia Liberty, is a high speed train built for the northeast corridor, manufactured by Alstom in Hornell, New York. These trainsets have a top speed of 186 mph with tilting enabled and 220 mph with tilting disabled, however when these trains enter service, initially they will reach top speeds of 160 mph until further improvements are made to the corridor. As of 2/20/2021, 2 prototype trainsets out of the 28 have been manufactured, with one testing at the TTCI facility in Pueblo, Colorado, and the second being tested on the northeast corridor. When testing is completed, they will return back to Hornell to get their interiors added. These trains are scheduled to enter service in 2021 through 2022, and will replace the old American Flyer Acela Express trainsets.
