BRIDGEPORT - Gov. Dannel Malloy today announced that Metro-North expects to resume normal service on the New Haven line in time for the morning commute Wednesday.

The Metropolitan Transportation Authority (MTA) says it has been working around the clock to restore train service. Crews today worked to remove the last three train cars from damaged Metro-North tracks in Bridgeport.

The National Transportation Safety Board will have investigators at the scene for the next week. NTSB authorities say the investigation is still in its early stages, and they don't yet know what caused the train to derail.

The shuttle train operation from New Haven to Bridgeport with a bus connection to Stamford will continue Tuesday.
