This is bad news for TfL. The slower return to offices means it has a £16 million deficit, and is facing a £150 million shortfall in projected income over the financial year. Meanwhile, its operating surplus has been revised down by more than £100 million. This puts even greater pressure on a service that in other times might be able to reinvest into expansion and repairs. Not least on the Central line, with its unreliable carriages, or the Bakerloo line extension. The lack of footfall, particularly on Mondays and Fridays, also creates huge problems for businesses paying high rents in the expectation of a steady flow of commuters.
