Transport Minister Norman Baker told BBC Radio 4's Today programme that the current fare structure was "not ideal", adding that the Government wanted to end above-inflation fare rises as soon as possible:
Forty per cent of fares, roughly, are regulated by the Government and that's a longstanding policy successive governments have had. The other 60% are unregulated and decided by the train companies themselves.
The balance of regulation and which fares are regulated is part of the fares and ticketing review we are now engaged upon.
It's not ideal - there are over 100,000 rail tickets and different prices each year to deal with. It's a hugely complicated issue.So it's important we try to get the best value for the passenger, the best value for the taxpayer and the simplest, (most) transparent system we can, given the need to ensure rail companies can price appropriately to attract people on to off-peak trains which might otherwise be running empty.
