bizzare request:

one of the london stations, I imagine one of the major ones, is a huge brick consruction and, if you look closely, you realise it is actually a train emerging from a tunnel...

if you're going down the thames, on the opposite side to the national theatre (i dont know london that well!) its right in front of you.. assuming you're going (i think) away from parliament

PLease somone on dis have an encyclopedic knowledge of station! i really wannt to find a piccie of it!
