Prime Minister David Cameron said the move, extending a freeze currently in place, would save an average rail commuter £400 between now and 2020.
The freeze would affect regulated fares, which cover about half of all tickets sold including season tickets and off-peak intercity returns. A restriction limiting rises in these fares to RPI (retail prices index) inflation has been in place for the past two years under the coalition government.
Mr Cameron will say, “The cost of commuting is one of the biggest household bills that hard-working families face and it is something we are determined to bear down on. It shouldn’t just be taken for granted that people across the country that get up early and come home late, spend a large amount of the money they earn travelling to and from work.”
Transport campaigners have called on any future government to start cutting prices.
