European Standard EN 50238 - Compatibilty between Rolling Stock and Train Detection Systems defines a process to obtain the assurance that specific rolling stock operating on a specific route does not interfere with train detection systems installed on this route.

Part 3 of EN 50238 deals with axle counters and the particular EMC requirements for their use in an electrified railway (although the document is also applicable to diesel-electric locomotives).

"Knowledge and error flow from the same mental sources, only success can tell one from another."
