Temperatures on the Underground have slowly increased as the clay around the tunnels has warmed up; in the early days of the Underground it was advertised as a place to keep cool on hot days. However, over time the temperature has slowly risen as the heat sink formed by the clay has reached its thermal capacity.

What is the hottest London Underground line?
Why is the Central line so hot? The Central Line is one of the hottest tube lines because of its age and depth beneath the ground. It is one of the oldest lines in London and was opened as The Central Railway in 1900 with early extensions carried out in 1920 and in the 1940s.

London is experiencing hotter and drier summers that are further impacted by the Urban Heat Island effect (UHI). The UHI can cause London to be up to 10’C warmer than neighbouring rural areas. This is because the sun’s rays are absorbed by hard surfaces rather than by vegetation such as trees, plants and grass.

The interior of Earth is very hot (the temperature of the core reaches more than 5,000 degrees Celsius) for two main reasons: The heat from when the planet formed, The heat from the decay of radioactive elements.
Why are subways so warm?
The heat from the friction of brakes is immense, and it has nowhere to escape to. Furthermore, all of the transformers on the subway cars, that convert the incoming electricity from the third rail into a usable current also generate significant heat in doing so.
Why is London underground so loud?
The vibration caused when metal train wheels roll over metal tracks is carried through the tunnel and the ground around it to nearby buildings. The walls and floors of these buildings can amplify the noise. We monitor reported noise levels across the Tube network.
