Bridgeport (AP) — Federal officials say the section of railroad track in Connecticut where two commuter trains collided last week had been inspected two days before the accident.

Robert Kulat, a spokesman for the Federal Railroad Administration, tells the Connecticut Post  that Metro-North inspectors looked at the track on May 15 and found it to be in good condition.

More than 70 people were injured in Friday's accident just outside of Bridgeport, and rail service in the area was disrupted for several days. Full service was restored Wednesday morning.

The National Transportation Safety Board has said it is looking at two sections of rail found at the crash scene which appear to have broken apart, to determine if the damage occurred during or before the crash.
