After a prolonged series of delays and missed deadlines, Amtrak has officially set a start date for its fleet of next-generation Acela trainsets, known as Avelia Liberty trains. These new trains will run on Amtrak's high-speed service along the Northeast Corridor between Washington D.

The new trains feature 27 percent more seats and more daily departures, Amtrak said. They will have a top speed of 160 miles per hour, 10 miles per hour faster than the current fleet.

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.
