Perhaps I should declare an interest as a former employee of British Rail. Network Rail promised a year ago to move towards a seven-day railway, yet we have seen no progress. For example, in Lewes, between 1 January and the end of March, on 11 weekends there were rail replacement buses instead of a proper train service, which is simply unacceptable. Is it not time to give Network Rail an incentive to move towards a seven-day railway, and would it not be a good idea to reduce ticket prices by, say, a third, when there are rail replacement buses?
