NTSB Says Brakes On NYC Train That Derailed Were Working Properly

Investigators didn't find anything to indicate that the brakes on a train that derailed last weekend were not functioning properly, National Transportation Safety Board officials said at a press conference Tuesday.

The Metro-North mechanical department performed a proper brake test prior to the train leaving the station and there were no anomalies, officials said.

A Metro-North commuter train derailed in the Bronx on Sunday, killing four people and injuring at least 60.

The train's operator reportedly told investigators that he was "in a daze" before the train crashed, according to CNN.

The train was reportedly traveling at 82 miles per hour in a 30-mile-per-hour zone when it derailed.

An alcohol test on the train's operator came back negative.
