Ms Bridget Prentice

To ask the Secretary of State for Transport, Local Government and the Regions what plans his Department has to replace the current fixed block signalling system on London Underground lines with

(2) which discount rates were used for sensitivity analysis of the effect of changing discount rates on the relative levels of the public sector comparator and the bids for the London Underground PPPs; and if he will make a statement. [10472]

Mr. Jamieson

The Government's plans for a publicly run, privately built tube will deliver around £l 3 billion of investment to improve the underground's infrastructure over the next 15 years. London Transport has yet to receive final bids on these plans. Consequently, it is too early to say whether changing the discount rate will lead to a switching point.

When final bids are received they will be evaluated for value for money on a variety of financing and discounting scenarios.

Ms Bridget Prentice

To ask the Secretary of State for Transport, Local Government and the Regions how many lines on the London Underground were subject to delayed or cancelled services on Tuesday 23 October; what the cause and length of the subsequent delay was for each line; and if more than one line was affected at any one time. [11559]

Mr. Jamieson

This is an operational matter for London Underground, which confirms that 10 lines (Central, Circle, District, East London, Hammersmith & City, Jubilee, Metropolitan, Northern, Piccadilly, Waterloo & City) were affected by delays (of at least 15 minutes) and/or cancellations. They have provided details of delays, their cause and duration as follows:

more modern systems; if the moving block computerised system has been considered as an alternative; and when new systems are likely to be implemented. [11561]

Mr. Jamieson

This is a matter for London Underground Ltd. to consider.

London Underground has undertaken £84 million of signalling improvements since the Government announced plans for the modernisation of the tube on 20 May 1998. A further £27 million of improvements are being undertaken in this financial year.

The tube modernisation plans will deliver a massive increase in the level of investment across the underground. Examples of signalling improvements to be delivered in the first period of the contracts include new signals on the Northern line to get the full benefit from the new trains; replacement of the Victoria line signals as part of a complete modernisation package; an upgrade of the Jubilee line signalling; a new signalling control centre on the Piccadilly line; improved signal reliability on the Bakerloo line; and greater signal capacity for the Waterloo and City line. In addition, all the signalling on the Circle, District and Metropolitan lines will be renewed in the next 10 years.

The signalling improvements to be delivered are specified in terms of the outputs required; it is for bidders to decide what type of technology will best achieve the necessary results.

Ms Bridget Prentice

To ask the Secretary of State for Transport, Local Government and the Regions how many delays on London Underground were reported to have been caused by problems with(a) track and signalling and (b) rolling stock in the latest year that figures are available; and if he will make a statement. [11560]

Mr. Jamieson

This is an operational matter for London Underground, which defines delays as intervals of 15 minutes or more, which is the threshold for granting refunds to passengers under the customer charter. In 2000–01, the latest complete year for which data on delays are available, delays were attributed as follows:(a) track on 236 occasions, and signals on 662 occasions; (b) rolling stock on 569 occasions.
