Meanwhile, British Transport Police asked “London Swifties” if they were “ready for it”, a reference to the star’s song of the same name.
Swift is due to play eight shows in London as part of her tour, with the first three taking place on Friday, Saturday and Sunday.
She is then set to return to the capital for five more nights in August.
In total, London will host more performances of the Eras Tour than any other city in the world, with nearly 700,000 people attending the shows.
It was revealed on Thursday that Swift’s fans were expected to boost the London economy by £300 million.
Emma Strain, TfL’s customer director, told the BBC that the Tube map “brings two icons together” and pays “homage to Swift’s love of London”.
She added: “London is blessed to have eight dates for the Eras Tour, and we’re encouraging people to get out on the transport network to explore the many locales namechecked in Swift’s songs and see the exciting range of live music events across the city this summer.”
