Rail users in Scotland will see a 3.6% increase in regulated rail fares from January 2018.
Abellio ScotRail can raise fares by as much as the Retail Prices Index (RPI) figure for July. This figure is the highest since 2011, when it was 5%.
Passenger groups said commuters would be worst-hit, and called for a halt to the increases.
The Scottish government said it had restricted the rise to ensure Scotland had the lowest price rises in the UK.
Peak fares are pegged to the retail prices index. The Scottish government currently limits rises in off-peak fares to RPI minus 1%.
Transport Secretary, Humza Yousaf, said ministers had restricted the annual increase to ensure Scottish commuters were cushioned from the rises.
He added: “At the same time we have introduced a number of initiatives to support passengers including offering a free week’s travel – equal to the cost of a rail fare freeze – which has been taken up by 90% of season ticket holders.
“While there has to be an increase in fares to support rail services our actions ensure the annual increase for key fares is never more than inflation and that any increase for off peak fares is always less than inflation.
“This allows us to continue to invest in improvements, to grow passenger numbers and to ensure rail travel is fair, affordable and an attractive alternative to travelling by car.”
