Transport for London still needs Government help for major transport projects despite making a £162 million annual “profit”, Sadiq Khan warned on Thursday.TfL is expected to declare its first ever “operating surplus” at the end of the month – cash it can reinvest in the capital’s public transport network.However the mayor said this was insufficient for big ticket “capital” projects, such as replacing the 52-year-old trains on the Bakerloo line, the extension of the Bakerloo line to Lewisham and Hayes, new trams in Croydon or Crossrail 2.Passengers on the Central line are suffering ongoing delays caused by chronic problems with its 32-year-old trains that TfL can only afford to repair rather than replace.Chancellor Jeremy Hunt made no mention in Wednesday’s Budget of a long-term funding deal for TfL.TfL had been seeking about £500 million a year for four or five years but was handed only a one-year £250 million deal last December.
