Amtrak said it is experiencing heavy delays for trains between New Haven and Boston following a fire.
An Amtrak transformer in Branford exploded and burst into flames on Meadow Street.
The fire spread to a boat and dump truck below it but no injuries were reported.
According to Twitter, power was out from Shore Line to Old Saybrook because of a fire but crews are working on repairing damage now.
Amtrak trains along the shoreline were experiencing congestion. One Acela train traveling from Boston to New York, carrying more than 200 people, was disabled and lost power near Guilford. Passengers were transferred to another train.
