State of the Underground

Using data not previously available, State of the Underground analyses a recent 20 per cent increase in delays on the Tube by type of delay and line affected.

Our key findings, based on this performance data are:

• Since the upgrade programme began in 2003/04 network delays per year have reduced by 27 per cent
• August 2010 to January 2011 saw the longest sustained period of poor performance on the Tube since upgrade work began
• The main reason for delays on the four worst performing lines - the Jubilee, Victoria, District and Metropolitan - was equipment failure.
• Industrial action accounted for nearly half of the increase in lost passenger hours between 2009/10 and 2010/11
• In the last eight years passenger journeys increased by 17 per cent whilst service levels rose by just two per cent.

Key recommendations:

The report calls on the Mayor and Transport for London (TfL) to set out how they will address this recent unacceptable level of performance. It also recommends a review of industrial relations following a series of disruptive strikes over the last year.

The Committee has set a target that for 2011/12 every London Underground line should at least match its best performance from the last eight years. The report is accompanied by summaries of individual Tube line performance from 2003/4 to 2010/11. Passengers can see how their line has been performing and compare it to the performance of the rest of the network.
