HC Deb 17 July 2001 vol 372 cc99-100W
David Winnick

To ask the Secretary of State for Transport, Local Government and the Regions on how many weekdays this year the Jubilee underground line has been run without interruption. [4504]

Mr. Jamieson

This is an operational matter for London Underground who inform me the standard they used to measure "without interruption" is that there are no service delays of 15 minutes or more. They have provided the following information for this financial year to date (1 April 2001 until 23 June 2001): the Jubilee line has run for 24 days out of 56 without interruption. The 24 days does not include four bank holidays which are treated as weekends rather than weekdays. Of the remaining 32 days, there were three in which the delays were attributable to external factors, such as a person on the track, and two where suspect packages caused delays.
