Investigation continues into deadly Metro-North derailment

The National Transportation Safety Board (NTSB) is investigating the cause of yesterday's MTA Metro-North Railroad derailment in the Bronx, N.Y., which resulted in four deaths and dozens of injuries.

The accident on the Hudson Line occurred just before 7:30 a.m., when a southbound train carrying about 120 passengers derailed just north of the Spuyten Duyvil station, Metro-North officials said in a press release. All cars derailed.

The railroad is operating limited service on the Hudson Line today.

NTSB investigators are determining whether speed was a factor in the derailment, according to news media reports.

The derailment marks the second major incident in eight months for Metro-North. In May, about 73 people were injured when a Metro-North train collided with another train traveling in the opposite direction.
