For all the Tube lines that don’t have air-conditioned trains, what is the estimated date by which each line is expected to have them?

Transport for London (TfL) is introducing on-train air-conditioning as older trains are replaced.

The entire 1973 Piccadilly line fleet will be replaced, with 94 state-of-the-art, air-conditioned trains starting to arrive in passenger service from 2024.

70 new air-conditioned high-capacity trains will serve the Elizabeth line when it launches.

Subject to funding being identified, TfL would next look to replace the Bakerloo, Central and Waterloo & City line trains with new generation, air-conditioned trains during the 2030s.

With approximately a 40-year life span, the remaining trains on the Jubilee, Northern and Victoria lines have longer remaining lives. TfL would expect to renew the Jubilee and Northern line stock in the late 2030s, and the Victoria line stock in the early 2050s.

In the meantime, TfL has been implementing a long-term programme to reduce temperatures and make customer journeys more comfortable. TfL has removed heat from its station and tunnel environment by installing new cooling solutions, and has upgraded and installed new ventilation fans at a number of stations across the network.
