Probably not the most relevant thread but whatever.
Trains. Those old choochoomobiles. J Corbs has been pretty big on re-nationalising our rail network since forever and he wants to reduce fares too apparently, the economic argument seems pretty feeble to me since they compete with buses, carrs, planes etc and the "fairness" argument seems even weaker since I don't see how it's fair to make people who drive, walk, cycle or bus to work subsidise the commute of those who use the trains.
But then there's the environmental argument, which seems legit. Except maybe not, because a long commute is still not environmentally friendly when you take the train and the discussion around rail fares seems to be centred on people commuting from smaller towns to London or other cities. And subsidising such commutes would presumably increase their prevalence.
Can't remember why I started writing this post.
