Commuters in the region have described an average rail fare rise of 3.1% as "unfair".
Research by the TUC union shows UK passengers spend up to five times as much on season tickets as other European travellers.
One passenger at Norwich station told ITV News Anglia: "I've travelled all over the world and seen what marvellous railway systems they have elsewhere.
"We should have a marvellous railway system, but we don't unfortunately. Definitely we pay too much money for it, so the increases are frankly unfair."

The TUC said its study found that someone travelling by rail from Chelmsford to London spends 13% of their average earnings on a monthly season ticket, compared with 2% for an equivalent commute in France.
The TUC said the 3.1% rise in season tickets was higher than the expected growth in wages this year of 2.5%.
Transport Secretary Chris Grayling blamed trade unions for the price hikes
"The reality is the fare increases are higher than they should be because the unions demand - with threats of national strikes, but they don't get them - higher pay rises than anybody else.
"Typical pay rises are more than 3% and that's what drives the increases."
The rail industry insists the "vast majority" of revenue from fares covers the day-to-day costs of running the network.
The 3.1% rise means the cost of an annual season ticket from Ely to London is to go up by £164, and to Cambridge by £40.
A season ticket between Peterborough to London will go up by £205, and from Ipswich to London it's up by £208 to £6,548.
Meanwhile, a season ticket from Manningtree in Essex it will go up £180 to £5,888.
TUC general secretary Frances O'Grady said: "The most reliable thing about our railways is the cash that goes to private shareholders each year, but with the most expensive fares in Europe, that can't be right.
"It's rewarding failure and taking money away that should be invested in better services.
"It's time to take the railways back into public hands. Every penny from every fare should go back into the railways. The number one priority should be running a world-class railway service, not private profit."
