The Northern line is running at 130 per cent of capacity during peak times, while the Central and Jubilee lines are at 116 and 115 per cent respectively.

The figures revealed that evening peak hour capacity is 84 per cent.

The figures come just days after TfL announced it would increase passenger capacity on the Victoria Line by 275,000 passengers each weekday.

Conservative London Assembly member Tony Devenish blamed Transport for London’s (TfL) revenue losses on the overcrowding.

TfL is expected to make a £742m loss in 2019-20 on the back of Khan’s fare freeze and expensive bus subsidies.

Devenish said: “By depriving TfL of much-need revenue through his flawed partial fares freeze…the mayor has severely restricted the amount of money available for much-needed infrastructure upgrades.”

Khan announced a four-year TfL fare freeze for individual journeys as a part of his campaign for mayor in 2016.

The freeze was in contrast to Boris Johnson’s time as mayor of London when prices rose by 42 per cent over eight years.

A spokesperson for Khan said the policy made public transport “more affordable for millions of Londoners”.

They added: “He is also investing record amounts in modernising and increasing capacity on London’s Tube network.”

“This includes the huge transformation of Bank station, the Northern Line Extension, major new signalling on the Circle, District, Hammersmith & City and Metropolitan lines, and investing in major upgrades to stations such as Finsbury Park.”

Independent mayoral candidate Rory Stewart has indicated he would likely raise TfL fares if elected and Conservative candidate Shaun Bailey has also said a fare rise would be a “done deal” under him.

Stewart told City A.M. on Tuesday it “cannot make sense to be running a system that’s losing this much money every year”.

“Under Boris Johnson, TfL was generating a lot of money for the city a lot of time, but for various reasons – not all his fault – TfL under [Khan] has been losing money,” he said.

TfL and Khan were contacted for comment.
