Bob Crow, leader of the RMT transport union, has said that the announcement that rail fare increases are to be capped next year is a "total con".
Regulated fares in England could have gone up by 9.1% in January but they will now be a maximum of 6.1%.
"This is a total con that will still leave the vast majority paying inflation-busting fares to pump up the profits of the private train operators.
"For a few it will feel like having your wallet nicked with the mugger then handing you a few bob back to buy a pint. Nobody will be fooled by this political stunt.
- The average rise of regulated fares in maintained at 1% above RPI inflation
- The new year rise is based on the July 2013 RPI inflation rate, which was 3.2%
- The Government announced that the ability of train operators to add an additional 5% to some individual fares is to be limited to just 2%
- In January 2014, no regulated fare - which includes season tickets - can go up by no more than 6.2%
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."
Transport Secretary Patrick McLoughlin says the planned cap on rail fare increases - which the Government says could have been as much as 9.2% -could save some commuters hundreds of pounds a year.
Hard-pressed rail commuters facing inflation-busting season ticket fare increases in the new year are to be given some respite.
The Government has announced it is to cap the increases of regulated fares planned for January 2014.
It says the ability of train operators to add an additional five percent to some individual fares, as long as the average rise of regulated fares is maintained at one percent above RPI inflation, is being limited to just two percent.
This means that in January 2014, no regulated fare - which includes season tickets - can go up by more than 6.2%, with the average, as already announced, being limited to 4.2%.
Campaigners will gather at five London Tube and rail stations later this morning to protest against planned fare hikes and ticket office closures.
The Labour led demonstrations are taking place at Clapham South, Golders Green, Queen's Park, New Cross and East Croydon.
The Association of Train Operating Companies (ATOC) has defended the way rail companies apply the fare rises that Government policy allows them. While rail fares can only go up by inflation plus 1% that is the average figure which is why some fares have risen by much more today.
Edward Welsh, ATOC spokesman told ITV News: "Just as they might increase them above 4.2% they have to de-crease them elsewhere.
"It's like a traditional pair of kitchen scales. The Government ensures that all the fares come back to 4.2%."
