Unclear information on a website run by a major rail company has led to train passengers being overcharged.
People booking on the Virgin Trains website have not always been given information that purchasing two single tickets can be cheaper than buying a return.
Virgin, which operates the West Coast Main Line between London and Scotland through Birmingham New Street station, is amending the site and will consider applications from passengers who think they have been overcharged.
Callers to the company's phone line are offered the lowest fares, but visitors to the website are given a choice of returns which can be far more expensive than buying two singles.
A Virgin Trains spokesman said: "We recognise this clarification needs to be made. We are asking people who feel they may have been overcharged to contact our customer relations department and we will consider applications sympathetically on an individual basis."
