HC Deb 18 January 1993 vol 217 c64W
Mr. Darling

To ask the Secretary of State for Transport if he has made an official visit on the Piccadilly line to Heathrow since April 1992.

Mr. Norris

No. However, I am kept fully informed of service performance on all underground lines, and I am pleased to say that the Piccadilly line has been one of the Underground's most consistently reliable lines since April 1992.
