Regular train service has returned to Connecticut, five days after a derailment injured scores of commuters and damaged tracks.

Commuter rail service from Connecticut to New York City, along with Amtrak service between Boston and New York, was back on schedule Wednesday morning on one of the nation’s oldest and most heavily traveled railways.

Aaron Donovan, a spokesman for Metropolitan Transportation Authority, which operates Metro-North, said there were no major problems or delays reported.

He says trains are running at a reduced speed of 30 mph through the area where the tracks were repaired. He says that is standard practice for new tracks and was adding only a few minutes to the morning commute.
