I remember my visit to Canning Town station with the hon. Gentleman. It seemed that the interchange between the docklands light railway and the Jubilee line at Canning Town was satisfactory and was in no sense a second-class station. I shall write to him and to his colleague, the hon. Member for Newham, North-East (Mr. Leighton), about the architect who is designing the station. It is true that passengers will have to pass through a tunnel to get to the north London line interchange, but to have all three lines intersecting with interconnecting platforms would cost an extra £7 million. At this stage, at least, the hon. Gentleman advances no justification for spending that extra money.
