I've mentioned this before on another thread about the swiss map but for the uninitiated:

It's certainly a cool map and useful to get a general idea how many trains are around at any given time, but it's important to note that this is not real data. They use the train schedule combined with the projected delay to estimate track location. I'm not sure if it's because SBB has an interest in keeping reported delays low or if they think exposing real data is a security risk, but I noticed the data being fake on several occasions, for example:

- My train wasn't able to continue its journey and was stuck between two stations for a few minutes while the map showed it continue to the next few stations up until the point where it started moving again, when their App also showed it running with a delay of 8min.

- On several occasions: watching the map show a train roll into the station and driving off, while seeing from my window that the train is only just arriving when the map shows it as between stations already.

This is a simulated map based on published transit schedules. As I’m typing this I sit on a bus that’s nowhere to be seen on the map.

The amazing thing about this is if you zoom into ski resorts, it looks to have the live positioning of cablecars.

Even five minutes late gets you a red dot. Very Swiss.
