Thanks for featuring, author of the website here. This is the same version as the one I've first made back in 2006, the main dataset is a derived GTFS dataset from swiss raw timetables (HRDF) [1].
The position of the trains are interpolated, based on the departure / arrival times of stop times and is using the average speed. I've used to have also an hourly updater for the delays using the GTFS-RT dataset [2] but is gone due to lack of time. ATM there is no official dataset to give the live position of the vehicles, all the other websites are just interpolating positions based on the time delays.
The website still runs as hobby project, is not meant to be taken as source of truth for actual position of the trains, though I get many requests from trainspotters and photographers asking me for such feature :)
And for some routes you can sit and enjoy watching the route displaying actual train units [3] more a simcity-like feature :)
Thanks for the link, author of the website here. For this particular #swisstrains project I was using derived GTFS dataset form this one https://opentransportdata.swiss/en/dataset/timetable-54-2024... - this portal contains public transport data from all swiss transport operators (not only SBB)
Thanks for featuring, author here. This is the first version of the #swisstrains webmap which I've made 17yrs ago, it still runs for historical reasons, it used to fetch also live delays but the position of the trains were still interpolated, using the average speed between the two timetable stops.
The other clones are more or less using same technique, swiss transport agencies are not (yet) offering live position of the trains / vehicles, only the actual delays measured at stations.
