Probably most folk don't give a foc about who owns the trains as long as they work, run on time are clean and not too overcrowded.
What I will say is that it's too important to be left to the open market to run. There isn't an efficient rail system anywhere that isn't subsidised by a government, it's too important it's the very fabric of a nation's infrastructure. But the UK being the UK we're sure to foc that up, the HS2 is the latest gravy boat for the lawyers and consultants to get on. I say gravy boat rather than train as it's so huge, worth so much money to them and it will take forever for it to stop or slow down, greedy foccers.
Anyway, Corbyn is a man of principle but he's about 40 years too late, the socialist utopia was crushed by Reagan and Thatcher. Socialism works in a mixed economy, we only need to look to Scandinavia for an example of how it works. Unfortunately we don't have the same mindset and culture so it won't work here. Why? Because ourselves and our de facto bosses the US of A do business by confrontation- hammering out deals, hostile takeovers, lowest price tender, ect. It's how we conduct capitalism, the Scandinavians work collaboratively for the common good, not the individual's gain. Corbynism is doomed, the man's a CND supporter, nothing wrong with this very admirable, but it's a big vote looser and doesn't fit in with the UK majority view or US foreign policy so he's doomed. Rant over.
