Makes you wonder how they manage in Scandinavia, Siberia and Northern China with a much higer snowfall than we will ever get. Their trains still get through, and often on time yet in Blighty the slight suggestion of snow and everyone panics and the network closes down!
Not
quite true. While they do have the obvious benefit of knowing that they're likely to have snow for some time, they still get caught out and
do suffer delays - and often have major problems on the roads despite clearing roads (with snow ploughs rather than constantly gritting) and having winter tyres fitted by law.
The trains are of course built to cope with snow, with different designs than a lot of the stock here to stop the electrical problems we suffer, which obviously helps - but there are limits. Bear in mind that in Sweden, chances are it snows and then the snow settles and stays as is for some time - perhaps with more snow to top things up from time to time.
It doesn't quickly melt and freeze, as it does here. That said, Sweden has been having warmer weather in recent years and some of the problems we have is beginning to become more common there, which is perhaps causing the increased problems that you can read about in the Swedish press (or thelocal.se if you want to see it in English).
The line I use when I'm in Sweden to go into Stockholm generally has 2tph (and not that much more in the peak) so it clearly has a lot less to worry about than our services into town which can't cope with even relatively small delays because of the knock-on effects. The number of passengers is significantly lower on many lines, so there's less chance of thousands of people being left stranded too.
Yet, if people
are caught out then at least roads are still drivable in most cases because everyone has winter tyres. If we fitted them here, perhaps with insurance companies giving incentives to make it more affordable, our road network wouldn't grind to a half at the first few flakes. I doubt we could ever make fitting them compulsory, at least not until our climate changes a lot more to become like Scandinavia.
