Tube Delays: Piccadilly Line

Tube escalatorSignal problems are the biggest cause of disruption on the Piccadilly line.

Staff issues, including industrial action and problems with the train fleet are the other significant issues.

Delays are measured by what TfL call Lost Customer Hours (LCH). These are calculated by multiplying the delays in minutes by the number of passengers. TfL records all delays over 2 minutes. It uses the financial year from April to March and splits the year in 13 equal periods for performance measurement.

 

Data in the London Underground Performance Almanac for the last full year shows there was an average of 205,014 Lost Customer Hours per period on the Piccadilly Line.

LCH Piccadilly

The Piccadilly ranks in 4th place for the worst record on the network, but it has improved considerably in the past 10 years. It has reduced Lost Customer Hours by 69% in the pas 3 years compared to 2003/06.

Tube Delays: Metropolitan Line

Oyster Reader Tom Page Wikimedia commonsThe Metropolitan Line is the oldest on the Tube network and the oldest underground line in the world, starting life in 1863 as the Metropolitan Railway running between Paddington and Farringdon.

Despite its age it has one of the lowest levels of delays on the network. Signal failure is the main cause of lost time, accounting for 23% of delays, compared to a network average of 14%.

Transport for London measures delays in what it calls Lost Customer Hours (LCH). These are calculated by multiplying the delays in minutes by the number of passengers. TfL records all delays over 2 minutes. It uses the financial year from April to March and splits the year in 13 equal periods for performance measurement.

Data in the London Underground Performance Almanac for the last full year shows there was an average of 94,441 Lost Customer Hours per period on the Metropolitan line.

Along with the District, Circle, and Hammersmith and City lines a modernisation project is about to get underway on the Metropolitan including up dates to the signals system, which TfL admits “belongs in a museum” although still functions safely.

Tube Delays: Jubilee Line

Tube stationThe Jubilee is the newest Tube line but it faces an age-old problem for every urban underground – delays caused by its passengers. This was the single biggest factor in 2014/15 causing 22% of time lost compared to 17% for the whole network.

Delays caused by what TfL calls “customers and public action” include commuters taking ill, items dropped on the track and people jumping in front of trains. The grim “person under a train…” message is familiar and more than 20 people a year kill themselves on the Underground.

Transport for London measures delays in what it calls Lost Customer Hours (LCH). These are calculated by multiplying the delays in minutes by the number of passengers. TfL records all delays over 2 minutes. It uses the financial year from April to March and splits the year in 13 equal periods for performance measurement.

Data in the London Underground Performance Almanac for the last full year shows there was an average of 292,033 Lost Customer Hours per period on the Jubilee line. This makes it the second highest on the network after the Central line.

LCH Jubilee

While the Jubilee line has seen an improvement over the past 10 years in Lost Customer Hours the numbers rose slightly at the start of 2015/16 year in April.

The Jubilee line is the only line to see “stations” listed as a significant source of delay. Although the line was opened as recently as 1979 a number of its stations date back 100 years and were used by other lines originally. The line was extended in the 1990s though the Docklands to Stratford.

Tube Delays: Central Line

tube speeding pastThe Central Line suffered the highest level of delays of any line on the Tube network in 2014/15. Apart from industrial action, which happens in one off events, the biggest cause of delay was train fleet problems. This accounted for more delays on the Central Line than any other.

Transport for London measures delays in what it calls Lost Customer Hours (LCH). These are calculated by multiplying the delays in minutes by the number of passengers. TfL records all delays over 2 minutes. It uses the financial year from April to March and splits the year in 13 equal periods for performance measurement.

Data in the London Underground Performance Almanac for the last full year shows there was an average of 410,144 Lost Customer Hours per period on the line. That is 29% higher than the second most delayed line, the Jubilee.

LCH Central

Over the past 10 years as Lost Customer Hours have been reduced across the network the Central line has remained a persistent offender. It has shown the least improvement in all lines since 2003/04.

The Central Line opened in in 1900 and its flat fare of 2 old pennies from Bank to Shepherd’s Bush earned it the nickname of the Tuppenny Tube. In the 1990s it became the second line after the Victoria to introduce automated operations where the train is largely controlled by a computer system monitored by a driver. Unlike the Victoria Line, automated operations are not a significant cause of lost hours on the line.
