Revealed: the tube line that'll be the hottest this summer

Research reveals that during hot summers, London's Underground can become uncomfortably warm. The Victoria line emerges as the hottest with expected temperatures reaching 32C this August. The Central line, once the hottest, is now anticipated to reach 31.2C. The Bakerloo line is also set to experience high temperatures, potentially hitting 30.1C.
