If there’s one place you don’t want to be during a heatwave, it’s on the Tube.
In the unprecedented high temperatures hitting London on Monday and Tuesday, the advice from TfL is to only travel if your journey is essential.
Mayor Sadiq Khan has also dissuaded Londoners from venturing out. He said: "Only use public transport if your journey is absolutely necessary. Plan ahead, carry water and be prepared for delays."
Few will need much persuasion to buy into that advice, although some journeys will be more unpleasant than others.
Avoiding the Tube all together by taking an air-conditioned Overground, Thameslink or Elizabeth Line service should be less uncomfortable. Those who are forced to use one of those services because they don’t live by a Tube line, often having to put up with less frequent services and slower journeys, can for once feel smug in the relative cool.
Air conditioning can also be found on some Tube lines. It should be less of a sweat fest on the Circle, Hammersmith & City, District and Metropolitan lines.
However, there is no such joy on any of the other London Underground lines: Central, Bakerloo, Jubilee, Victoria, Piccadilly, Waterloo & City, and Northern.
