Accident Report Detail

Derailment of Amtrak Train on Louisville and Nashville Railroad

Executive Summary

About 12:50 p.m. on October 1, 1975, 1 locomotive unit and 11 cars of Amtrak train No. 315 derailed on the Louisville and Nashville Railroad Company's track near Pulaski, Tennessee. Of the 69 persons on the train, 31 were injured. Property and equipment damage amounted to about $1,067,000.

Probable Cause

The National Transportation Safety Board determines that the probable cause of this accident was the overturning of the outside rail in a 3 degree 8 min curve by high lateral forces induced by the six-wheel truck of the SDP-40-F locomotive; these forces exceeded the capability of the track which met current FRA standards. The speed of the locomotive, although not greater than the speed allowable for Class 4 track, was too great to be sustained by the track.
