This European Technical Report has been prepared to provide a technical basis for determining the laboratory test parameters (load, angle and position of load application) to be used when carrying out repeated load tests according to the method of EN 13146-4, taking into account evidence from both track testing and theoretical analysis and also considering experience in using the past versions of the EN 13481 series of standards. Statistical variations in applied loads and their influence on safety factors are also considered. This report may be used to determine and justify loading parameters which will be required by future versions of the EN 13481 standards, including cases outside the current Scope of those standards e.g. track with wider support spacing, higher axle loads, sharper curves, etc.
