The railroad said late Tuesday that modified service between Newark, N.J., and points south will resume on Wednesday. That includes restoring Virginia service to Lynchburg, Richmond and Newport News, Keystone trains in Pennsylvania and Downeaster service between Boston and Portland, Maine.
However, Amtrak said in a statement that the amount of water in train tunnels under the Hudson and East rivers is unprecedented, preventing service to New York.
There will be no Northeast Regional service between New York and Boston and no Acela Express service for the entire length of the Northeast Corridor. No date has been set for resumption of service.
