“…not only did Iryo train's front carriages which stayed on the track have "notches" in their wheels, but three earlier trains that went over the track earlier did too.”

This sounds like something a camera mounted on a sample of trains watching a wheel could catch.

It would require a very high speed camera, and a floodlight, which may be impractical.

As a train wouldn't have the space??

Not necessarily, no. Train underframes can be quite crowded and this equipment is very industrial.

Japan, Germany, France, China, and the UK check their tracks at high speed. I don't know if Spain does, but there are news articles about them ordering such an inspection train in 2019: https://www.railjournal.com/infrastructure/adif-orders-high-...

The camera would probably only need to look at a very small section at high speed. They could be specifically made to film the tracks or the wheels of the train. Such cameras exist. Not cheap, but even some YouTubers have similar ones, to film high speed impact videos of things going much faster than trains. Might be worth it for trains.

More simply, you measure the impact for dangerous forces. No need to overcook it.

Too much processing. Accelerometer or even a microphone would do the job.
