PHILADELPHIA (AP) — Federal officials announced Saturday that Amtrak must immediately expand its use of a speed restriction system on Philadelphia's northbound rails where a speeding train reached 106 mph, flew off the tracks and crashed, killing eight people.
The Federal Railroad Administration said an emergency order would be issued in coming days that calls for Amtrak to ensure the presence of the automatic train control system that notifies an engineer when a train is above the speed limit and automatically applies the brakes if the engineer doesn't act to slow the train down.
The system is already being used for southbound trains approaching the curve where Tuesday's derailment occurred. Amtrak said it would abide by the federal directive and others announced Saturday, adding that Amtrak's "overarching goal is to provide safe and secure rail passenger travel."
