Should the UK government subsidise the cost of train fares?
No. Provided you buy in advance, rather than buying the most expensive ticket on the day of travel, the UK's train fares are amongst the cheapest in Europe.
No. Fare increases are in line with inflation, so capping this would take money away from maintenance and upgrades.
No. Subsidising rail fares would mean that poorer taxpayers, who use trains less frequently, are paying for the commutes and regular long distance travel of the rich.
