Real-time map of Dutch rail traffic

The Belgian railways have a similar thing, which is on an official site: <a href="http://www.railtime.be/website/traffic-trains" rel="nofollow">http://www.railtime.be/website/traffic-trains</a> There's not much traffic now since it's midnight. Also, the banner on top is completely Javascript.

Someone posted a similar thing for the London Underground from Matthew Somerville about 2 years ago here (can't find the hn link):<p><a href="http://traintimes.org.uk/map/tube/" rel="nofollow">http://traintimes.org.uk/map/tube/</a>

Very nice! There is not much information on the website, do they use the regular schedule to calculate the train positions or something more sophisticated (GPS positions broadcasted from the train)?

I built something like this for Caltrain: <a href="http://epall.github.com/animated-caltrain/" rel="nofollow">http://epall.github.com/animated-caltrain/</a>

There's a similar one for Swiss trains.

This is awesome!
