It's one thing to be a continent away hearing about the 'London subway bombings' and it's quite another to be in one of the underground tunnels thinking about what is must have been like with a passage like this full of people and smoke and heat. This is one of the stations that was bombed and they are still working on repairs. In another part wiring and such is still exposed and you can see here that the walls are bare where formerly they would have been covered with colorful advertisements.
