Anthony Smith, chief executive of rail customer watchdog Passenger Focus, has welcomed the cap on rail fare increases.
He said: "Passengers will be pleased to hear that the amount train companies can raise individual regulated fares by has been limited.
"We have been calling for this to happen for years - it is a step towards a fairer system. This will allow passengers to plan with a bit more certainty and have confidence that actual regulated fare rises will bear more relation to the figures set by government."
The Government today announced it is to cap the increases of regulated fares planned for January 2014.
Rail fares are going up in January but they have been capped and will increase by a maximum of 6.1%.
