I tend not to read links from people who dont post anything with them.
But anyway, here's another one for you that goes into far more detail. As i keep saying, the UK is pretty much middle of the road:

I've already explained this upthread but high speed rail lines are the flagship projects of most big state railways in Europe. They're excellent and lead to impressive statistics. We don't have one, and that's not changing any time soon. As soon as you remove them from comparisons and look into non high speed and regional services, there is very little difference across the major countries. They're all subject to the same problems and delays regardless of who owns them. Nationalisation will make next to no difference, just as privatisation didn't back in the 90s. The most likely outcome of bringing them back under state control is that it will just cost more.
