To ask the Secretary of State for Transport, Local Government and the Regions what the (a) total passenger capacity and (b) the theoretical maximum capacity of London Underground was at peak periods in 1996–97 and 2001–02; and what changes in capacity resulted from (i) new lines, (ii) new trains, (iii) signal upgrades, (iv) speed restrictions, (v) signal failures, (vi) supply failures, (vii) line failure and (viii) structural problems.
(a) LU advise me that they do not measure, as part of their regular monitoring, the number of passengers which they are able to carry on the tube network as a whole. Instead, they have information which shows that in 1996–97 and 2001–02, during peak hours, the busiest short sections of the underground's lines carried totals of 133,450 and 142,401 passengers per hour respectively.
(b) LU have figures for the design capacity of their rolling stock. This is the number of customers the rolling stock can physically carry and is defined by the manufacturer without taking into account the quality of the journey. An assessment can be made of the design capacity of trains scheduled per hour, at peak times on the same busiest short sections of each line. This gives figures of 308,278 for 1996–97 and 315,514 for 2001–02.
(i) to (viii) LU inform me that this information does not form part of their regular monitoring and could be provided only at disproportionate cost.
