The NTSB investigation into the train derailment is continuing today after four people were killed and at least another 67 were injured in the commuter train accident in the Bronx at 7:20 am on Sunday morning.

Train employees aboard the train are cooperating with authorities as they look toward the cause of the derailment. Nothing has been ruled out as yet as investigators look to the tracks for a possible cause as well as mechanical error. Event recorders have been located and collected from the locomotive as well as the front car of the train.

Cadaver dogs have made the final sweep through the area and authorities are confident that all dead and injured have been located.

Although cranes have begun to place the toppled cars back onto the track, the rail repair will not take place until the NTSB concludes their investigation. That investigation is slated to take a week to ten days to complete.

It has been determined today that the train was traveling at 82 miles per hour when it derailed at the sharp curve that was rated as a 30 mile per hour turn. All seven cars and the locomotive which pushed the seven-car train from behind, jumped the tracks.

The train’s engineer, a 20-year veteran, who has been described as experienced, diligent, and competent, stated that even though he had applied the brakes, the train did not slow down as they approached the curve. He reported to authorities that after the train failed to stop after applying the brakes, that he utilized another braking procedure called “dumping” the brakes, that also failed to slow the train.

In July, another train, that one a freight train, jumped the track in the same spot damaging over 1,500 feet of track. But, officials are saying that the two incidences are not deemed to be related at this point.

About 150 passengers were aboard the train when it derailed.
