An extension of the Docklands Light Railway is also at risk, the report concluded.
Crossrail 2, a proposed £40bn north-south line, and an extension of the Bakerloo tube line have already been put on hold.
Mr Khan had sought a £15.8bn long-time period funding offer to repair service TfL’s finances and make it possible for it to continue with a sequence of badly wanted updates.
The authority, which is approximately twice as dependent on fare profits as identical-sized towns overseas, was strike hard by the pandemic. It has already gained practically £4bn of taxpayer handouts.
But the Governing administration as a substitute supplied £1.08bn to hold the Tube, trains and buses managing right up until December. In return, Mr Khan agreed to assessment the feasibility of driverless Tube trains, increase fares and slice costs.
A spokesman for Transportation for London explained: “We continue to function with the Governing administration on our longer time period funding so we can system efficiently for London’s foreseeable future. We are offering transformative additions and enhancements across the transport community, these kinds of as completing the Elizabeth line, the Northern Line Extension, the extension of London Overground to Barking Riverside, new signalling on the Circle, District, Hammersmith & Metropolis and Metropolitan traces, and the Financial institution Station Up grade.
“Our Money Sustainability Approach, posted in January this year, sets out what we want to provide and outlines how long-time period funding certainty will allow us to provide these economically and efficiently. However, the progress of new important projects, which are very important for decarbonisation, improving air top quality and supporting new properties and work, is reliant on the final result of discussions more than our longer time period funding.”
