This map shows all trains currently on approach to a particular station. The yellow pins are stations, the red/green dots trains (green going north, red south). The trains move in approximately real time, or rather quicker if you check the speed-up box.
Live departure data is fetched from the National Rail website, much like my timetable site, and then it does a bit of maths and magic.
