The London Regional Transport Act came into force in 1984. However, the level of the Underground's funding for 1984–85 was determined by the GLC. On current estimates, Underground investment in 1990–91 will be two and a half times higher, in real terms, than in 1984–85.
To ask the Secretary of State for Transport what surveys have been made of the impact of the opening of the channel tunnel in 1993 and of the Waterloo link upon the numbers travelling by the Northern line.
A survey carried out by Halcrow Fox for British Rail in 1989 estimated the numbers of channel tunnel passengers that would be using the Underground. London Underground is making use of the resulting data in its strategic planning.
