This is, apparently, the worse snow-fall that London has seen for 18 years - we 'normally' get only one or two even mildly snowy days a year, if that. I, for one, would be unhappy paying for the infrastucture (snow ploughs, gritting machinery for all roads, training, staffing etc. etc.) at the level of Toronto and Moscow for approximately one day's use out of every 600. With train fares at the level they are I would be unhappy to be paying for heated rails etc. etc. again for a minimal use every year. The justification that TFL has is that our general climate does not justify expenditure on snow chains, skid training etc. for our buses and bus drivers. It may well be that we are due to see increased extremes of climate which will cost-justify such expenditure, but snow, in London, is still an extraordinary event. Central London, with its office etc. population, is normally sufficiently warmer than the surrounding countryside that snow rarely has a chance of settling - the fact is that we had a snowfall on Sunday evening - when the capital is probably at its coldest, as the heat sink which is its concrete and pavements (like a big storage heater) has had most time to dissipate. I am very glad that TFL (and local authorities) do still undertake some form of cost:benefit analysis. I couldn't afford their charges if they decided to invest against any eventuality, however unlikely. As it is, for a day or two every couple of years at most, we have a little disruption to our lives, a day off school or work, perhaps, a little inconvenience. And the cities you write of are also disrupted when their weather is (for them) extreme - think of the ice storms that devastated North America some time back, and I can recall reports of hypothermia deaths in Moscow. They had prepared for their (normal) snow, but not for those extremes.
