I do not recognise that there is a total collapse of services, but I agree with the hon. Lady that London Underground has serious problems. The hon. Lady will find that many of the staff losses relate to the introduction of automatic ticket processing, which brings a saving in booking office staff. The Northern line replacement has not been cut. It remains in the programme for the mid-1990s, after the Central line's £700 million programme has been completed. I challenge the hon. Lady on the question of mileage, because there have been no discernible mileage cuts in London underground services.
