Acela 2 Over The Cove. On March 1, 2024, Amtrak/Alstom Acela 2 Train Set 8 crossed Shaw's Cove in New London, Connecticut while operating as non-revenue train 846. On Thursday, August 28, 2025, long-awaited revenue service will commence with this model on the Northeast Corridor Line between Boston, Massachusetts and Washington D.C. The train brings some increased speed to the trip, but also adds much needed capacity. Though it will begin with a pair of weekday roundtrips, eventually 28 train sets will enter service.
