According to Amtrak, no Vermont service on the Vermonter, or Ethan Allen Express, until further notice:
“Vermonter (Washington – St. Albans): No service north of New Haven (Monday-Saturday) and no service on Sundays.
Ethan Allen Express (New York – Rutland, VT): No service north of Albany”
Obviously, Vermont is north of New Haven and Albany, so no trains for a while up here. The Vermonter will continue to run between New Haven and DC Monday to Saturday.
