Tube Lines had another strong quarter; all three lines were better than target for Availability, a measure of delays caused by infrastructure failures, although the number of recorded incidents rose by 3% over the year between quarter 2 2008/09 and quarter 2 2009/10. Tube Lines also beat its Ambience target, the measure of train and stations cleanliness, and facilities service points were 40% better this quarter than when Tube Lines took over responsibility for its three lines, although the target was narrowly missed.
Safety performance remains better than target this quarter. There were two RIDDOR reportable lost time injuries and the lost time injury frequency rate (LTIFR) remains low at 0.04 which means that employees and contractors working on Tube Lines’ sites are 20 times less likely to have an injury than back in 2003 when the LTIFR was 1.40.
Progress was made with the Jubilee line upgrade; six trains were operated with the new signalling system against the London Underground timetable and final installation work was ongoing. During this quarter Tube Lines put in a request for five planned weekend closures to be extended geographically to enable the completion of train testing between Stratford and Green Park; discussions on a revised closure timetable are ongoing.
The Northern line upgrade progressed well; by the end of this quarter a total of 18 trains were fitted out with the new transmission based train control equipment of which six have now had rigorous off-site tests carried out on them.
There were 32 zero delays days over the quarter, an improvement on the 27 in the same quarter last year.
Capital expenditure for the quarter was £88.9m against a forecast of £86.8m
