London Underground upgrade contractor Tube Lines is 35% up on its 'availability' measure - the performance indicator for lost customer hours - during the last quarter.

The contractor also posted good performance on the Northern line, with sub-contractor Alstom keeping fleet incidents down.

More than half of Jubilee line trains have been upgraded with new signalling equipment, with the time taken to install the equipment reduced by almost two-thirds to 13 days. The Northern line fleed will be adapted next.

Six more station upgrades reached practical completion, bringing the total to 58. Work has begun on a further five.

Capital expenditure for the quarter was slightly less than planned at £98M, compared with a forecast £101M. For 2008 as a whole, the expenditure was £204M compared to a forecast of £205M.

There were 29 zero delays days over the quarter.
