It was announced today that the average season ticket price could increase by 3.5% in January.
That's based on today's inflation figure of 2.5% - and another 1% added on top for investment.
But with train companies allowed to put tickets up by another 2% - it means commuters could face a hike of over 5%.
Which could mean commuters forking out an extra £400 a year.
Responding to the publication of July’s Retail Price Index (RPI) inflation figure of 2.5%, which helps determine season tickets and other regulated train fares for 2015, an Abellio Greater Anglia spokesperson said:
Rail Minister Claire Perry said she sympathises with passengers who have had to contend with "inflation-busting fare rises almost every year over the last decade" but insisted the Government was committed to "fair fares".
Rail passengers will see the average price of their tickets increase by 3.5% from January, according to figures out today.
"We're a victim of our success" Michael Roberts, Director General of the Rail Delivery Group, representing train operators and Network Rail, said.
Mr Roberts told Good Morning Britain that the UK's trains are so busy because they are affordable, refuting claims that fare hikes are pricing people out of rail travel.
The cost of some train tickets could be almost 6% higher next year.
Rail commuters will be paying close attention to the announcement of last month's Retail Prices Index (RPI) figure today, as it will be used to calculate increases to next year's regulated fares, including season tickets.
Ticket price rises are capped at 1% plus the July RPI figure, expected to be around 2.6%.
Train companies can add another 2% to some fares, as long as the overall average remains as per the formula.
Campaigners say ticket prices are rising four times faster than the average wage and that the measurement used to calculate fare increases has been discredited.
The RMT union, which campaigns for the railways to return to public ownership, has said that next year's fare rise is a "kick in the teeth" for rail passengers.
Rail fares could rise by as much as 5.5% next year under the current system, ITV News' Consumer Editor Chris Choi reports:
Rail travel is being pushed "out the reach of some ordinary people" by fare increases, the head of a public transport advocacy group said.
Stephen Joseph, executive director of the Campaign for Better Transport, told Good Morning Britain that Government-dictated ticket price hikes mean rail fares are rising four times faster than wages.
Commuters will find out how much rail fares are likely to rise by next year when the Retail Price Index (RPI) for last month is released today.
The annual increase is capped at July's RPI plus 1%, with an extra 2% added to some tickets.
