After FCC introduced new restrictions on the use of cheap day return tickets during the evening peak , the number of complaints almost tripled to 254 per 100,000 passenger journeys.

Association of Public Transport Users spokesperson Adrian Jackson-Robins , who lives in Harpenden and commutes to London , said: "The restrictions might have made commercial sense for the company but it was a public relations disaster that motivated a vociferous body of people to complain."

He added: "There have been a series of disastrous days on the line which have also generated a large number of complaints, but in fairness to FCC most of these problems have not been of their making. They have been down to Network Rail."
