As we see from my earlier survey link, a small proportion of the population opposes public ownership of railways by the British public. Dum is one of them.
He does not comment on public ownership of our railways by foreign governments or investors.
Government direct subsidy of the railways is around £5 billion per year, an increase of over 200% since privatisation
Between 1995 and 2018, rail tickets on average went up 20% in price, taking into account inflation.
