> Signalbox's technology identifies the train a device is on by matching a snapshot of smartphone data to a train’s trajectory data. The technology uses advanced algorithms works even with severely degraded data. We are able to pinpoint a smartphone to any type of train without background location tracking or hardware. Hmm, that's...interesting?
I would like to be able to see when each road/section was built. I assume with GoogleEarth and other databases it should be possible to run some kind changelog comparison and do this at scale for at least the last 20 years or so.

I wonder what app has allow location on all the time and is feeding them their data

Checkout the French equivalent : https://carto.tchoo.net . Looks more complete. Past similar HN submission got no attention, whereas the UK's top page. Interesting ! https://news.ycombinator.com/item?id=45249351
I remember my colleague from MFF UK, Robert Babilon, producing his first real-time map of Czech trains in 2004. The page, called Babitron, still exists and still keeps that delightful 2004 look. I visited it a few days ago. Unfortunately today there is a message "We are moving Babitron to a different server", so the link isn't working. https://kam.mff.cuni.cz/~babilon/zpmapa2

1. So it's Trainline on a persons phone that is tracking this info and using it to enrich this service? I use Trainline and didn't know it was doing that, but I do have location permissions on because I was told that powered the search picker when I started using the app.
2. What did they use _before_ Trainline? Or was Trainline selling user location data to them?

Few questions, wonder if anyone knows the answers: 1. So it's Trainline on a persons phone that is tracking this info and using it to enrich this service? I use Trainline and didn't know it was doing that, but I do have location permissions on because I was told that powered the search picker when I started using the app. 2. What did they use _before_ Trainline? Or was Trainline selling user location data to them?
Or their API - it also expects device location data:
> At a minimum, requests to the detect endpoint _must_ contain a device's location measurement. Additional fields can be included where available to improve the accuracy of the returned results as outlined below.

I think you're misunderstanding what they are saying. They don't use background location data, but they do use your current location data. Try the "Find My Train" demo on their site - it asks for location permission. Or their API - it also expects device location data: > At a minimum, requests to the detect endpoint _must_ contain a device's location measurement.

I think you are missing the point - what is collecting data on all those trains.
