The first allows you to look at near real-time locations and delays of all DB long-distance passenger trains in Germany and adjoining countries. Also you can go back in time and look at how trains were doing, a day ago, a week ago, a month ago. You can also run it like a video to see the flow during the course of a day, and speed things up so that you can look at a days worth of data in minutes.
The other is a You Tube video produced by a MIT computer lab for SNCF showing the movements and delays to TGV trains over the course of a week. The interesting thing is that the train lateness is shown in a chromatic scale from Green (on time) to Red (>5 minutes late) with shades in between showing relative lateness. In addition the size of the dots from small (100- 200) to large (800 or more) gives an indication of how many people were inconvenienced.
