Even if commuters don't end up feeling the full force of inflation on their season ticket next year, price rises could still add hundreds to the cost of travel.
Season ticket price rises for next year are usually set based on the July inflation figures, which were released this morning. However, with inflation soaring, the Department of Transport has pledged to limit the extent of increases.
The Retail Price Index (RPI) was 12.3% in July, the highest rate since March 1981. Usually the price rise for regulated fares, which make up about 45% of tickets including season ones, is based on this, and would see prices increase by an overall average of this amount plus one percentage point, 13.3%.
