The Northeast Regional Train No. 188 that derailed on Tuesday had been traveling at speeds similar to earlier trains along the route from Washington to Philadelphia. A National Transportation Safety Board official said that train engineers are expected to know the speed restrictions along the entire route.

Where the Safety System That Might Have
Prevented the Accident Has Been Installed
The derailment area was not yet equipped with a safety system called positive train control that is designed to keep trains below maximum speed. Congress has mandated that all rail lines have the system by year’s end. Amtrak has installed it on three sections of the Northeast Corridor. “Based on what we know, had such a system been installed in this section of track, this accident would not have occurred,” said Robert Sumwalt, a member of the National Transportation Safety Board.

Train Was Going Twice the Speed Limit
The train derailed at about 9:21 p.m. along a curved stretch of track about eight miles from where the train left 30th Street Station in Philadelphia. An official with the National Transportation Safety Board said the train was traveling at about 106 miles per hour when the engineer applied the brakes, just moments before the derailment.

A Scene of Devastation

Most of the train’s passenger cars tumbled onto their sides and crumpled. The first car was mangled almost beyond recognition.
The engine pulling the train separated from the passenger cars and came to rest diagonally across another set of tracks.
