At this time no official announcements on Amtrak's website, potentially a victim of the new rules over at X. You have to go to Amtrak's account at X to see the alerts, although Amtrak could have put together a synopsis in their own words in order to (gasp!) provide communication to the public.
This is what is affected so far:
Friday's 93 and 141, which normally operate to Norfolk, terminated in Washington, DC. 95, which also goes to Norfolk, operated normally. Friday's 125, which operates to Newport News, still did so.
Saturday's 82 and 88, which normally originate in Norfolk on Saturdays, instead started in Washington. Assuming that 158. the third Norfolk equipment set that arrived as 95, will still run, but we should know after 1 PM. Saturday's 194 is running as normal from Newport News.
