Rail fare increase: Commuters tales of woe
Some rail fares will rise by an average of 6.2% in January - more than double the rate of inflation - although other price rises may be higher.
The Retail Prices Index (RPI) measure of inflation in July - which stands at 3.2% - is used to calculate the rises.
Some English fares will rise by RPI plus 3%, while in Scotland they will go up by RPI plus 1%. Wales has yet to set a figure for its increase.
Some complained of not enough carriages, crowded trains and cancellations.
