BRIDGEPORT - The National Transportation Safety Board (NTSB) released new information today on the train derailment in Bridgeport that injured 70 people.

An inspection two days before the accident turned up a problem with the rail joints, according to a NTSB report.

In response to the report, MTA officials say a track inspector noted a potential problem but didn't think it warranted immediate attention.

MTA officials say the inspector noted the ballast needed tamping earlier that week, meaning the stone around the tracks was too loose. They say the inspector planned to check back on the area of interest, but by that time it was too late.

A member of the Connecticut Rail Commuter Council called the oversight “unfortunate.” Some lawmakers say the oversight is unacceptable.

MTA officials say that a full inspection of the entire track system is in the works.
