London city authorities will make 500 million pounds ($567 million) available for the British capital's transport network to cover gaps left by a government support package, Mayor Sadiq Khan's office said on Wednesday.
"(The funding) is designed to ensure that TfL's budget will balance in light of the gap," it said in a statement, adding that otherwise services would have been threatened.
TfL, which runs the city's red double-decker buses and underground Tube trains among other services, agreed a 1.16 billion pounds ($1.3 billion) deal with the British government in August to run until end-March 2024.
The mayor's office said the shortfall in funding, in spite of the support package, would have meant "huge service cuts" if TfL could not deliver a further 230 million pounds in savings.
The 500-million-pound facility will be financed by the taxpayer-funded Greater London Authority, with TfL having the option to tap funds until March 2024.
Britain's government has stepped in with a number of funding packages for TfL since the start of the pandemic, when lockdowns caused a fall in passenger numbers, pressuring the transport network's finances.
