Amtrak says its new next-generation Acela train sets should start service on the Northeast Corridor in the spring of 2025.

Earlier this year, if you happened to be standing at a train station in New Jersey at a certain time of night, you might have seen a sleek new high-speed Acela zip by. The trains, which did 900 test runs between January and August, are expected to start commercial service on Amtrak’s Northeast Corridor line next spring.
