you’re thinking anywhere on the platform, I’m suggesting a known place near a station by which the train passes and its location - at that moment - is known.
All the system needs is a ground-truth location after a certain amount of time. GPS is just a cheap and convenient way to do it almost anywhere, but this location correction doesn’t need to be satellite-based at all.

Yeah maybe that could work. I definitely agree that there’s ways to get good anchor points. Maybe through cross-check with wireless networks even.
