The draw-LFGSS-on-London ride

Ill dig it out at some point but when i was at csm we had a project called mapping in which I deconstructed the tube lines and rearranged them to make other objects.

csb.

is there a map that shows the real world route for the tube lines ?
overlaid on an A-Z or something like that ?

and i'm also very curious as to where the eurostar line goes after it leaves stratford and heads underground ? where does it re emerge from the tunnel ?
