When I saw the Ebb and Flow of Melbourne Trains by Flink Labs, it sprang to my mind that producing a similar animation in Google Earth could be done pretty easily using Google Earth's time slider. I made this animation for the trains going to and coming from the station of Leuven, the city where I daily commute to by train.

I scraped the time schedule data from the National Company of Belgian Trainways (NMBS) website. Hopefully someday they will provide their data in a more convenient way like Google's Transit Feed, for now only scraping was possible.

You can see the result in the following video:

I plan to add another video showing different view points in Google Earth and to develop an animation for another station, probably Antwerp Central Station.
