Some rail passengers across the South could end up paying a staggering £10,000 a year to get to work over the next 12 months. An annual ticket from Swindon to London will cost around £8000 without tube fares and car parking.
The 3.1% rise is for regulated fares which include season tickets. The increase on unregulated fares, typically off-peak leisure tickets, is not capped.
But a number of these fares, including some on the East Coast route, are going up by much less than 3.1%, with the overall rise in tickets - regulated and unregulated - being 2.8%.
Here are examples of rail fare rises.
Folkestone Central -London £4,984
West Malling-London £3,996
