It was caused by a single fatigue crack in one wheel which, when it finally failed, caused the train to derail at a rail switch.

The failure occurred from a manhole cover near the base of the tank, and it is possible that a fatigue crack there grew to the point of criticality.

He was supported by similar direct analysis of failed axles by Joseph Glynn, where the axles failed by slow growth of a brittle crack in a process now known as metal fatigue.

While fatigue cracks are normal in aircraft, the usual occurrence is that a crack develops slowly and stops once it reaches the end of the panel of which larger parts are assembled.

His and other papers suggesting a crack growth mechanism through repeated stressing, however, were ignored, and fatigue failures occurred at an ever increasing rate on the expanding railway system.

Most experts believe that the crack that caused the crash was one of a series of shallow fatigue cracks that began between the crown of the rail and the inside of the bend, called the gauge corner.
