@lynnesbian Oh, I heard that before at work. I'm pretty sure the axcel counter with that particular problem was designed by my coworker xD

That thing was programmed in assembly and only had analog relays as an interface. It's not even produced anymore, but has a lifespan of like 30 years, and railway operators don't just replace working equipment.

Though it is strange that this is a law. Usually such "safety requirements" are handled by the railway operator.
