> 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.

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?
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. Additional fields can be included where available to improve the accuracy of the returned results as outlined below.
You are giving it to them. That's why the demo asks for your location permission, and that's why the API expects location info.
"You" here means another app that integrates their API (or you as an individual using the demo on their website). How the other app gets it is up to the other app - ideally it also just queries it directly and requires location permission.
This only seems to be standard overground trains. If you add in metro networks like the London tube, or light rail / trams like in Manchester, then you’d get at least hundreds more.
The map includes metros across the Tyne and Wear Metro in NE England, and while its not perfect, it's by far the most useful train live tracking I've ever seen. There's quite a few places in the UK with different rail systems that don't fit together (and have apps of varying quality/usefulness)
very cool. Unrelated but anytime im looking at a map be it city roads, rails subway, etc i wish there was a way to filter the layers based on construction date.
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 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.
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 !

The title matters a lot. Without "real-time" this submission has likely gotten the same lack of attention.
There's one for the Czech network (one of the densest in the world, if not the densest) https://grapp.spravazeleznic.cz

Hmm, that's...interesting?
Seems similar to Transit's approach: https://blog.transitapp.com/go-underground/
I wonder what app has allow location on all the time and is feeding them their data

https://docs.signalbox.io/docs#/operations/Detect_detect
wait - so you think that the map is made up of people who are all sitting on that website using the Find My Train demo?
I think you are missing the point - what is collecting data on all those trains.
No, live train data in the UK is already publicly available, e.g. see https://www.opentraintimes.com/
This is matching your phone's location to the already public train data.
> This is matching your phone's location
But what is getting that?
You are giving it to them. That's why the demo asks for your location permission, and that's why the API expects location info.

Here is the map made by the Swedish transport authority: https://www.trafikverket.se/trafikinformation/tagkarta/
Hungary https://vonatinfo.mav.hu/
Here's the Danish one (with some trains in Sweden): http://landetspuls.dk

Off-topic, I don't get why people still use a www subdomain, especially so in this case, www.map. Conway's Law in action?
this reminds me of the London specific equivalent posted awhile back: https://londonunderground.live (previously discussed https://news.ycombinator.com/item?id=43651390). Also the Boston equivalent https://tmap.live.
I would love to see this for Germany :D
https://travic.app/
Basically all of Europe, with varying levels of detail.
Used this many times during the longer commutes across country, works well.
Would be useful if they add real time cop location information so you can avoid getting arrested for the crime of being white while being assulted.

Topping out at 10 minutes delay for the most severe marker colour is an interesting choice.
It would be better if they were aligned to the delay repay thresholds.
Certainly would not work out in Germany LOL
