Ok, so this is so cool I just had to blog about it. Using some departure data fetched from the TfL API along with a bit of maths and magic, Matthew Somerville (with helpful hinderances from Frances Berriman and James Aylett) made a live train map for the London Underground. Yes, that’s right, this map shows all trains on the London Underground network.

The yellow pins are stations, the red pins trains. The trains move in approximately real time.

Apart from that you can also stalk all trains currently on approach to a particular station via this live train map.

Note that this was done in only a few hours at Science Hackday.
