The prime minister has told BBC South Today's political editor Peter Henley that he is not happy with rail fare hikes that have seen prices go up 6.2% in southern England, compared to 3% in Northern Ireland and 4% in in Scotland.
David Cameron said the government had "inherited a system that's seen above inflation fare increases year on year".
Mr Cameron claimed he was determined to run railways more effectively and help "hard-pressed commuters in the region".
