Oh No! Not Rain
It rained last night in London. This is not news. This is not even an uncommon occurence. Granted, it was heavy rainfall, as evidenced by the windows of the restaurant in Soho last night being drenched every time a car went up Wardour Street and by the tree branch which was floating off down the road outside my house.
None of this explains why our public transport infrastructure seems to come to a sudden shuddering stop everytime the weather (rain, snow, autumn leaves, frost, ice) for which this country is reknown, actually happens. I'm sure the Victorians didn't have this sort of problem when they built the railways and I'm sure they had pumps to get rid of the rain when it collected, inconveniently, in tunnels too.
