RAILROAD ACCIDENT REPORT

Adopted: August 30, 1972

DERAILMENT 0F AMTRAK TRAIN N0 1 WHILE OPERATING ON THE ILLINOIS CENTRAL RAILROAD NEAR SALEM, ILLINOIS JUNE 10, 1971

I. SYNOPSIS

Amtrak train No. 1, consisting of 14 pas- senger ears and an Illinois Central Railroad Company (ICRR) four-unit diesel electric loco- motive, while operating southward from Chicago, Illinois, to New Orleans, Louisiana, over the tracks of ICRR, derailed near Salem, Illinois, on June 10, 1971. The first two locomotive units and the first seven cars were turned over on their sides. The accident resulted in 11 fatalities and injuries to 163 people

The National Transportation Safety Board determines that the probable cause of this accident was the displacement of the east stock rail of the southward main track by the false ﬂange on the left-hand wheel on the leading axle of the rear truck of locomotive unit 4031 This wheel slid flat when the traction-motor armature bearings failed and locked the driving wheels Failure to detect the sliding wheels Was caused by the dispatch of the locomotive with an inoperative wheel-slip indicator

The cause of six of the eleven fatalities was the ejection of passengers through the large side windows which broke when the cars overturned. The other fatalities were caused by passengers heing ejected from the end of the car, or being struck by a cross tie, or being hurled against the inside of the car. A total of 163 passengers and employees were injured when impacted against injury—producing surfaces inside the cars.
