Here are two links to a very interesting webcam at the very busy Olten Station in Switzerland. Olten is the crossroads of rail passenger service in Switzerland, and sees a fair bit of freight too. Olten is a surprisingly small town (~17,000 pop.) in the Canton of Solothurn, with a passenger service better than most cities boasting populations in the millions. Two links are provided, try them both to see which works better with your browser. Both will open in frames, they refresh rapidly, and one of the frames will show the schedule for passenger trains which updates as time progresses.
This one is likely best if you have a browser plugin for MPEG videos
And this one should work better if you have a Mac or use a Quicktime plugin
Currently Switzerland is seven hours ahead of Central Daylight Time.
Enjoy.
