In this Sunday, Dec. 1, 2013, file photo, first responders work the scene of a derailment of a Metro-North passenger train in the Bronx borough of New York. A National Transportation Safety Board report released, Friday, Oct. 3, 2014, describes gouges in the cars’ walls, jammed doors, dislodged seats and hundreds of broken windows after the Dec. 1 accident on the Metro-North Railroad. The NTSB hasn’t determined the cause.

NEW YORK — A federal report indicates that the commuter rail engineer whose train was speeding when it derailed in New York City, killing four people, went 24 mph over the speed limit on the same run a few days earlier.

A document released Friday by the National Transportation Safety Board showed the results of tests that used data recorders to look back at the speeds of trains run by engineer William Rockefeller.

The NTSB would not offer analysis, but charts show that Rockefeller broke the speed limit on four of the six runs tested. And at one point his train was going 54 mph in a 30 mph zone.

In the Dec. 1 derailment in the Bronx, the train was heading into a 30 mph curve at 82 mph. More than 70 people were injured.

Rockefeller's lawyer said Friday he would comment at the appropriate time.
