Retail portfolio manager Rob Callaghan, 49, from Leighton Buzzard, said: "It is ridiculous. A rail fare increase would have virtually no impact on overcrowding as people don't have any choice but to commute in by train." But George Muir, director general of Atoc, said there was no way of avoiding rail peak pricing if train use continued to increase. If national road pricing came into force it would "tend to push" more people on to the trains, making extra charges "inevitable", he said.
