Central line passengers waste more of their lives due to delayed trains than those on any other Tube services, it can be revealed.

Passengers on the route lost a combined total of over 1.8 million hours due to delayed trains in the first six months of this year, according to a recent TfL report.

The Central line is the busiest Tube line with around 260 million passenger journeys made each year.

Not far behind were the Piccadilly line, on which passengers lost a total of over 1.4 million hours, and the Jubilee line, which recorded over 1.2 million lost passenger hours.

Total lost passenger hours are calculated based on the number of people affected by any delay greater than two minutes.

Top five total customer hours lost (January 10 - June 26) Central - 1.815 million

- 1.815 million Piccadilly - 1.469 million

- 1.469 million Jubilee - 1.263 million

- 1.263 million District - 1.107 million

- 1.107 million Circle/Hammersmith & City - 1.098 million

In total, almost 9.5 million hours have been lost by passengers waiting for trains on the London Underground network during the first six months of this year.

The Central line saw a particular spike in delays in March, with 453,000 lost customer hours recorded, due in part to a power fault at Bow station.

But the majority of delays were due to train failures, followed by "customer and public issues" and then signal faults.

However, TfL has said that delays across the Tube network are at their “lowest ever levels” and have been reduced by nearly 40% in just the last five years.

Peter McNaught, Operations Director for the Central line, said: “I'm sorry for the disruption that Central line customers experienced during this spring. In March, the power supply equipment at Bow substation developed a fault which prevented us from running a full service on what is one of our busiest lines.

“Our engineers worked around the clock to fix the fault and delays have now fallen hugely.

“We are also investing millions to upgrade Central line trains to make customers' journeys better before we introduce a brand new fleet that will increase capacity by 25 per cent.”
