BRIDGEPORT - Commuters who ride Metro-North trains will be coping with service disruptions for several days or even weeks after a train derailed in Bridgeport last night and swiped another train that was headed in the opposite direction.

The MTA has an advisory on its website advising that there will be no Metro-North service between South Norwalk and New Haven until further notice. The railroad says there is regular train service between Grand Central Terminal and Stamford, and trains will run hourly between Stamford and South Norwalk.

Bus service is being provided between Waterbury and Bridgeport, with no train connections.

The MTA says normal services will resume once an investigation into the incident is complete and the trains have been moved away from the tracks. They have not given an estimated completion date.

At a news conference this morning, local and state officials cautioned commuters who live east of Bridgeport to begin making alternative travel arrangements.

Officials say 70 people were hurt last night when an eastbound train derailed and clipped a westbound train, tearing part of it open. Three people remain in critical condition at area hospitals.
