Amtrak dropped the "Express" from all references to the train when it launched the Nonstop, presumably because to use both Express and Non-Stop (when not all Express-es are Nonstops) would be confusing.
The date and observation of train name change can be referenced at "Amtrak debuts new amenities for Acela Nonstop service between New York City and Washington, D.C." Amtrak., further examples of the dropping of "Express" on all press releases since then at "Media Room", Amtrak
Normally I would need to request a move for this page, however the Acela article already existed with a Talk and Change history, so the content lives on there, and the Talk history of Acela Express is preserved in an archive here with the previous Acela Talk page (from when there were two articles) here Keizers ( talk) 01:18, 18 July 2020 (UTC)
- @ Keizers: There's already been discussion of the issue at Talk:Acela Express. This really needs a formal move discussion, and there's probably no need to preserve the old history at Acela. Mackensen (talk) 02:44, 18 July 2020 (UTC)
