Amtrak revealed the one of two completed trains for its new fleet of Acela trainsets being built.

The train was constructed in Hornell, New York, and will be tested in Colorado before the fleet enters service in 2021.

The new high-speed trains will have 25% more seats than older models, plus improved access ability and sustainability.

All aboard: Amtrak just released a video showing one of two prototypes for its new, high-speed Acela trains in action.

The new trains are part of a $30 billion infrastructure plan that Amtrak is implementing to update trains, fix old tunnels, and build new tunnels.

The new models have some upgrades that should make them more pleasant for Acela passengers, of which Amtrak counted 3.5 million for 2019. They have more seats and a new reservation system, plus touch-less technology in the larger bathrooms, and "tilting technology" to make the ride less jarring. Amtrak says the trains will do all of this, plus use 40% less energy per passenger.

Amtrak already released a preview of the interior in September.
