Introduction
Railway axles were among the first train components to give rise to fatigue problems.
Many years ago, specific methods were developed in order to design these axles. They were based on a
feedback process from the service behaviour of axles combined with the examination of failures and on
fatigue tests conducted in the laboratory, so as to characterize and optimize the design and materials
used for axles.
A European working group under the aegis of UIC started to harmonize these methods at the beginning
of the 1970s. This led to an ORE document applicable to the design of trailer stock axles, subsequently
incorporated into national standards (French, German, Italian). It was consequently converted into a UIC
leaflet.
The method for this standard is based on the ca
