A sufficiently large RLCDNN would reinvent the Doppler effect from data, eight?

- atoav 5y agoYou could also let Tom the traindriver sit there and have him guesstimate the speed.
- fho 5y agoOr just have two switches on the train tracks
- pbhjpbhj 5y agoRadar exists too. The need might be for a sensor local to the platform as a back up to give warning for a train that's traveling too fast? In which case a sensor that mimics the old Cowboy film favourite of putting one's ear to the track seems like a reasonable thing to try.
- Ekaros 5y agoOr some other type of sensor and minimal gear added to each locomotive...
- atoav 5y agoAh, we're talking about practical solutions here? Should've warned me. A chain of laser reflective sensors might be even better, because there is less mechanical wear + you can use them to know where the train currently is and where it isn't. But this is very likely a very well researched area and there are definitly train people who can point out a flaw in this idea (dirt?)
