The Fairfield Patch
is also reporting a shuttle service is operating:
The Rail Traffic Controller based in Grand Central advises conductors to tell passengers there is a major delay between South Norwalk and New Haven, Patch contributor Harold Cobin reports. Link
The controller says they are attempting to establish eastbound shuttle service to New Haven.
Buses are arriving at Norwalk Police Headquarters at South Main and Monroe streets to transport passengers east. The police headquarters is a block east from the South Norwalk train station.
The eastbound trains are operating normally; first stop Stamford. I would guess the westbound trains are operating 'all-stops' since they can't guarantee the connection at Stamford with the local.
It'll be a l-o-n-g trip from New Haven to GCT, but hey at least people aren't stranded.
In the Amtrak Forum someone wrote they were on the first eastbound Amtrak train that was blocked. They reversed back to Penn Station and passengers were sent to the Port Authority Bus Terminal. ;(
