Rami, having spent many years on Chicago el’s and the tube, I can say they have a similar feel. After the Chicago subway was constructed, London called in one of the designers as a consultant, a Mr. Yrkes.
Never mind standing over plague pits at Algate (if you’re in the City of London, you’re probably within 100m of standing over a plague pit), if you’re on the Central Line platforms at Liverpool Street you’re standing BELOW a plague pit. That’s right. Hundreds of dead bodies, above your head.
I agree. I went to London last summer, accidentally during the Jubilee celebrations, so it was (apparently) extra-full of people. I wish my daily commute in Chicago smelled as bad as the Underground, although I did have a little trouble finding my way to a couple of places.
