Very old London Underground game

This is a long shot, however in the first few years of high school (some time between 2000 & 2003) I remember spending time during my break periods getting accustomed to the internet at school. One of these days I was so happy to find an official game on the then TfL website aimed towards kids. That games objective was to control the movement of underground trains on a track and have them arrive and depart safely. Now its funny to think how back then I would never have imagined that I'll be working for LU, but I've recently remembered the game and for nostalgias sake, I wouldn't mind playing it again. Google hasn't been very helpful and I cannot for the life of me remember the name of this game! 

Anyone remember what this game was called but better still where I can find it?

EDIT: just as I post and remember a tactic of searching google by date, I find this, however no game
