However, Mr Parr tried to return this way a couple of weeks ago, just after the East Coast main line had been taken over by a private operator. When he presented his tickets, he was told that they were not valid because "that's a BR ticket, and we were privatised on Sunday".
Not only was Mr Parr made to pay pounds 37.10, with a receipt given on BR stationery, he was ordered to hand over the return sections of both his tickets, thereby denying the chance of a rebate. He was told they were the property of the privatised rail company.
Mr Parr was also denied the opportunity to pay merely the pounds 7 difference between the pounds 45 Leeds/London and the pounds 38 Preston/London fares.
Mr Parr was later told by a woman at the travel enquiry bureau at King's Cross that the saver tickets could have been used for the journey before privatisation but could no longer be used in this way. A BR spokesman, however, added to the confusion, saying Mr Parr had been lucky to get away with it in the past. "We withdrew the facility for these type of journeys six years ago," he said grumpily. "They were being undertaken by trainspotters and the like."
