The best railways in europe are in France and Germany and are part nationalised and subsidised by the state.
As far as I know there is only one party in the UK that wants to renationalise the utilities, so I presume that would include the railways, for the benefit of the British people and not just for big companies to make vast profits at the publics expense.
If they got in power then our railways could compete to once again be the amongst the best in the world
