There's nothing strange about that in itself - I do the Wood Green - Waterloo - Feltham thing at least once or twice a week, it's basically the only time I get any reading done.
What does amaze me, every time, is the particular smell Waterloo station has - specifically, the smell as one goes through the ticket barriers and through the ticket hall and up the stairs to the train platforms. It is so unique and hits you just as you set foot on the escalators. I wouldn't go so far as to call it acrid, but an increase in strength of about 35% would definitely put it into that boundary.

The only way I can think to describe it is by likening it to the smell one might get if one cooked a kilo of dust in a steamer per person to go through Waterloo, then sprinkled it with a generous helping of iron filings, and added some essence l'aluminium to boot.
It saddens me to think that the benefits I've gleamed through (just about) giving up smoking are probably outweighed by passing through Waterloo station a couple of times a week.
