3 LONDON UNDERGROUND PERFORMANCE REPORT PERIOD (16 OCTOBER 1 NOVEMBER 11) INTRODUCTION This report presents London Underground s performance during the four-week period ended on 1 November 11 along with trends over the last year. It contains a series of performance measures designed to reflect customers experiences of travelling on the Tube. A glossary explaining these measures is provided on pages to 6. CONTEXT London Underground trains serve 69 stations (this excludes Blackfriars which is currently closed) over a traffic day from approximately : to 1: (shorter on Sundays). London Underground is responsible for maintaining 6 passenger escalators and 19 passenger lifts. At 9: on Mondays to Fridays, 3 trains are scheduled to be in service on the network which covers route kilometres. In the last financial year, ended on 31 March 11, London Underground trains ran 68.9 million kilometres and carried 1,17 million passengers. PERIOD 8 PERFORMANCE Customer Satisfaction The second quarter s overall evaluation score was 79, the same as in each of the previous three quarters. The third quarter score will be available in period 1. Passenger Journeys A new demand record of.6 million passenger journeys was set in period 8, up by.7 million from the previous record established last period. To date, passenger journeys are 3 higher than in the first eight periods of 1/11. Journey Time Excess journey time improved (i.e. fell) by.1 minutes this period compared to last, as the effects of the periodic rise in demand described above was offset by improved service reliability. 3

4 Network scheduled journey time reduced by. minutes reflecting the first full fourweek period of working timetable 33 on the Victoria line. Train Service The network percentage of the scheduled kilometres that were operated, at 97., improved by 1 from period 7 and was the best result since period 3. This result comprised 97 of service in the Monday to Friday peaks and 97.6 in the off-peak. A total of 1 S-stock trains have been delivered to London, of which 16 are scheduled for running in passenger service on the Metropolitan line. Due to a number of reliability issues, a decision was taken in November to temporarily halt further deliveries to allow time for implementation of approved modifications and increased testing, ensuring further reliability improvements in advance of trains entering passenger service. Deliveries have subsequently resumed. Station Service There were 6 unplanned station closures in the period, one more than in period 7, with a total duration of 6 hours which represents just. per cent of scheduled station opening hours. The most significant causes of station closures this period were Defective Fire/Safety Equipment (1) Staff Absence / Shortage (11); Power Failure (8) and Customer Action (7). Network escalator availability was.3 (.8 excluding planned works) and lift availability was 9.1 (. excluding planned works). An upgrade to the LU electronic service update boards (ESUBs) was completed over the weekend of 8 and 9 October. Key new features are multiple statuses per line, and grouping of disrupted lines. Service Disruption - Lost Customer Hours The number of lost customer hours (LCH) decreased by 63, from period 7, and improving trends continued on all lines apart from the Bakerloo. Of particular note is the improving trend on the Circle and Hammersmith & City lines over the past year (page 18). The five incidents with the highest LCH values on each line are listed on pages 1 and.

Scheduled kilometres are the distances timetabled to be run, adjusted for planned engineering works. Percentage of schedule improved by 1 from last period to 97., which was.8 ahead of target and the best result since period 3. The Jubilee line maintained its recent improvement, achieving over 99 of schedule in the last week of the period. Only the Bakerloo line recorded a shortfall against its target: notable incidents included Network Rail track circuit failures on 3, 9 and 1 November; detrainment of stalled Virgin trains at Wembley and South Kenton on November; and a medical fatality at Oxford Circus on 11 November. 6

Central Victoria District Metropolitan Circle & Hamm Jubilee Northern..6. Piccadilly Waterloo & City NETWORK Higher percentages represent better performance Peak Offpeak The graphs show the percentage of scheduled kilometres operated by trains in passenger service on each line during peak and offpeak periods. Peak is defined as Monday to Friday 7: to 1: and 16: to 19:, excluding public holidays. Scheduled kilometres are as defined on page 3. Peak percentage is usually lower than offpeak as the more intensive service levels operated during peak times means that any disruption causes a larger loss of service than at quieter times of day. At network level, the exception in period 1 of last year was due to industrial action on Boxing Day. 9

Piccadilly Waterloo & City NETWORK Higher percentages represent better performance Weekday Weekend The graphs show the percentage of timetabled kilometres operated by trains in passenger service on weekdays and weekends (inc. Bank Holidays) and illustrate the impact of weekend engineering works on service output. The graphs show that most recently the biggest impact of engineering work has been on the Subsurface lines (District, Metropolitan, C&H) as part of the SSR upgrade, altyhough there was little impact on the Metropolitan line this period. The Circle & Hammersmith line in particular had extensive works in period as the 3-day block closure between High Street Kensington and Edgware Road was extended to also include other sections of the line at weekends. The progressive reduction in weekend work affecting the Jubilee line over the past year is also evident; there was none requiring line closures in period 8. There was one weekend closure of the Victoria line in period 8 for decommissioning of the old signalling system and asset replacement work at Finsbury Park -the third site to be switched to the new signalling system. 1

For a full station closure, all station entry and exits must be closed and trains non-stopping. LU trains currently serve 69 stations (Blackfriars is closed). The 6 closures reported above had a total duration of 6 hours, which represents just. of scheduled station opening hours. The most significant causes of station closures this period were Defective Fire/Safety Equipment (1) Staff Absence / Shortage (11); Power Failure (8) and Customer Action (7).The high numbers in periods 8&9 of last year were due to industrial action. 11

The Jubilee line maintained its improved performance and the trend has levelled off following the increases that occurred when Transmission Based Train Control (TBTC) signalling was first introduced in period 1 of last year and then extended across the whole line in period of this year. There has been a recent upward trend in the number of signal-related incidents on the Victoria line; reflecting some specific issues experienced with track circuit failures that are being addressed as the final stage of the line upgrade continues. The Central line recorded 3 incidents including 11 due to Automatic Train Operation (ATO/ATP) faults and 7 due to an intermittent track circuit failure at Liverpool Street. 16

The results are ranked for each line and the network according to the current period values. Lost Customer Hours caused by 'Customers & Public' were significantly above average on the Bakerloo and Victoria lines. On the former the two most disruptive such incidents were a medical fatality at Oxford Circus during the evening peak on 11 November and a crime-related incident at Paddington in the morning peak on 18 October. On the Victoria line, sensitive door edge activations accounted for a little over half of the LCH in this category. 'Staff' LCH on the District line was mainly due to non-availability of train operators. 19

'Staff' LCH on the Metropolitan, Circle & Hammersmith & City lines included a disruptive signal passed at danger (SPAD) at Farringdon while on the Northern line an error at Morden depot caused a number of trains to be cancelled (see 'top ' incidents overleaf). These lines together with the Piccadilly also experienced cancellations due to non-availability of train operators. The Jubilee line graph clearly shows a marked reduction in Fleet and Signals LCH (where the impact of TBTC is reflected) compared with average performance over the last year.

23 London Underground Performance Report Glossary of Measures and Terms Customer Satisfaction This is measured by means of a continuous face-to-face survey designed to measure the level of customer satisfaction with the service provided by London Underground. An external market research company is contracted to undertake approximately, interviews every quarter. Customers are asked to rate their level of satisfaction with the service they experienced at their station of origin and last line travelled on. The ratings are scored on a scale of to 1 for 19 specific measures covering 8 train and 11 station attributes, and also for one single overall evaluation question. Results are presented as the average mark out of ten, multiplied by ten and rounded to the nearest integer value. Passenger Journeys The number of journeys undertaken by fare-paying passengers (including holders of Freedom Passes) on the Underground network. Percentage of Scheduled Kilometres Operated This is a measure of LU s performance in operating the train service that is scheduled to operate in passenger service. It is measured over the whole of the traffic day, seven days per week, and takes account of trains that are turned short of their intended destination as well as trains that are cancelled. Actual kilometres operated are expressed as a percentage of scheduled kilometres which are the distances timetabled to be run, as adjusted for any planned short-term changes to the timetable such as weekend engineering works. Excess Journey Time The Journey Time Metric captures service performance, related to demand, and expresses the information as average passenger journey time. For the purposes of the Journey Time Metric, each journey is broken down into its constituent parts namely access from station entrance to platform, ticket queuing & purchase time, platform wait time, on train time, platform to platform interchange and egress from platform to station exit. Each component has a perfect or scheduled value which states how long a particular journey would take if everything went as planned. Each period actual journey times are measured and then compared to the schedule. The differential between the two is the measure of lateness - referred to as excess journey time. Excess journey time is therefore a measure of how efficiently LU is providing its scheduled or stated service, the more reliable the service the lower the excess. The calculation includes the impact of planned closures. Each Journey Time Metric component or activity has a Value of Time (VOT) weighting associated with it. These weights vary according to how the customers perceive the activity e.g. a perceived time weight of is applied to platform wait time as customers regard waiting as an unattractive aspect of their journey. Total Journey Time The sum of the expected or scheduled journey time and the excess as defined above. Percentage of Schedule (Peak/Off-peak) This is a sub-analysis of the Percentage of Schedule as defined above which splits the measure between peak times (defined as 7: 1: and 16: 19: Mondays to Fridays excluding public holidays) and off-peak (all other times). The purpose is to separately measure performance when demand on the system is at its highest in terms of passenger numbers and number of trains in service. Percentage of Timetable (weekdays/weekends) These measures show how much of LU s timetabled service operates on weekdays (Mon-Fri exc. Public Holidays) and weekends (Sat/Sun and Public Holidays). The purpose is to illustrate the impact that weekend engineering works have on LU s service output volume. The measure consequently gives a more representative illustration of the level of service offered to the customer. Station Closures The number of unplanned full station closures measured throughout the whole of each service day. For a full station closure, all station entry and exits must be closed and trains non-stopping. Examples of causes of station closures include absence or shortage of staff; failure of lifts or escalators (usually 3

24 the former); security alerts; customer action; fire alert; police request; external factors (e.g. incidents in close proximity to the station). For management purposes each station on the network is allocated to an owning line and closures are reported accordingly. Escalator Availability The total hours escalators were working, or available to work if required, as a percentage of total scheduled service hours. Unavailable time includes that due to planned works in addition to time out of service due to faults. Machines switched off during off-peak times for reasons of energy conservation are deemed to be available (i.e. they would work if required to be switched on). Reporting of escalator performance by line reflects line ownership of the station in which the escalator is installed, rather than the line to which it provides access. So for example failure of an escalator that provides access to the Northern line platforms at King s Cross station will be recorded in the results for the Circle & Hammersmith line which is responsible for management of the station. Lift Availability The total hours lifts were working, or available to work if required, as a percentage of total scheduled service hours. Unavailable time includes that due to planned works in addition to time out of service due to faults. The measure includes all passenger service lifts i.e. those that provide the principal means of access to platforms for all passengers and those that are provided as secondary means of access for passengers for whom use of stairs or escalators is impractical. Reporting by line follows the same principle as for escalators above. Rolling Stock Mean Distance Between Failures (MDBF) The number of train kilometres operated in customer service divided by the number of rolling stock asset-related service disruptions of minutes or more, including items that are attributed but still in abeyance to be agreed. The incident attribution process means that some incidents initially classified as asset faults may be subsequently agreed as being caused by other factors, for example staff error or customer action. In such cases agreement of attribution could give rise to retrospective changes to the data. Signal & Points Related utes The number of signal & points (train control) asset-related service disruptions of minutes or more including items that are attributed but still in abeyance to be agreed. As with MDBF above, subsequent agreement of attribution for items in abeyance could give rise to retrospective changes to the data. Track Related utes The number of track asset-related service disruptions of minutes or more including items that are attributed but still in abeyance to be agreed. As with MDBF above, subsequent agreement of attribution for items in abeyance could give rise to retrospective changes to the data. Lost Customer Hours (LCH) Lost Customer Hours means the total additional journey time, measured in hours, experienced by customers using the Underground network as a result of all service disruptions with durations of two minutes or more. Hence an incident at Oxford Circus during a Mon-Fri peak will give rise to a much higher LCH value than an incident of the same duration in Zone 6 on a Sunday morning. There can be retrospective changes to LCH values as incidents are reviewed and agreed. Service Disruption Disruption occurs where an incident causes the train service or the station service to be interrupted. Cause Code Categories As well as attracting a Lost Customer Hour (LCH) value, all incidents that cause service disruptions are ascribed a cause. LU uses more than 3 cause codes to analyse causes of service disruption,

25 but for the purpose of the graphs on pages 17 and 18 of this report these have been summarised into principal groupings defined as follows: Customers & Public: Setting off alarms (malicious or spurious), robbery/theft, accidental track obstruction, suicide attempt, trespass on railway, vandalism, drunks, lost children, crowding, altercations/fights between customers, customers holding doors open, customer injury boarding/alighting trains, person ill on train. External Factors: Incidents caused by external parties or factors outside LU s control, including for example bridge strikes, fire in premises adjacent to the railway, local power supply failure, police request etc. Fleet: Trains defective in service or which are not available to enter service from the depot when required. Safety & Security: Fire and security alerts (e.g. unattended bags, fire alarms set off) station evacuations including exercises. Note that defects of Fire/Safety equipment are included under Stations Infrastructure. Signals: Failures of signal equipment, control systems for signals and points, tunnel telephones, and tripcock testers, including overruns of works to these assets. Staff: Absence, shortage, illness, accident, errors, staff taxi delays, refusal to work on health and safety grounds, industrial action. Stations Infrastructure: Failure of stations equipment (e.g. escalators, lifts, lighting, fire equipment etc), also overrun of stations project works. Track & Civils: Defects of Track, Bridges and Earth Structures and Drainage, Track fires, Track obstructions and vegetation impacts, overruns of Track/Civils work.
