The New York commuter train that derailed Sunday morning, killing four people, was going 52 miles over the speed limit at the time of the derailment, according to National Transportation Safety Board (NTSB) investigators.
Despite having such poor vision that he drove with a restricted (auto) license, a train engineer was medically recertified by his employer, Union Pacific Railroad. Those vision problems contributed to fatal 2012 head-on collision between two freight trains in Oklahoma, according to the National Transportation Safety Board (NTSB).
