The railway company is kinda behind on how the world (of data) works, and they have for a long time considered this kind of information as exclusive information that nobody else should be able to access. Despite being government owned..
The same thing happened in Belgium. A student made a mobile website for accessing rail times, was ignored by the rail company for 18 months, then got threatened into shutting down when the rail company finally made their own application (which naturally doesn't work as well). Luckily a few government ministers made the rail company see the light, despite their protestations.
Essentially, the data is always playing back the regular schedule, but is offset by any delays (which can now be obtained by API, earlier by scraping the railway's mobile site). Other than that they use the average acceleration and braking performance of trains, and the max speed at route points.
The project apparently never was finished: this works but isn't up to date. A very similar site and likely by the same maker won a "Who is better than Google" prize a few years back.
It's funny this link pops up now: the Dutch Railways announced an API on March 31st.
Oh, and then there's one for planes: http://radar.zhaw.ch/radar.html This actually uses real data (They have a transponderdata-receiver on the roof) and there's a Google Earth version: http://www.idp.zhaw.ch/de/engineering/idp/forschung/transpor...
and another one for planes http://www.flightradar24.com/
