Do Tube trains have air conditioning?

Subsurface trains These have standard air-conditioning, as the subsurface tunnels are large enough to displace the exhausted hot air.

Is the Tube well ventilated?

While much of the network sits in well-ventilated ‘cut-and-cover’ tunnels, just below the surface, some stations lie more than 50 meters down, in ‘deep level’ tunnels. This, in turn, increased the temperature of the surrounding clay so much that, today, average tunnel temperatures are between 20-25°C.

Why is it so hot in the Tube?

Over the years the Tube tunnels have been heated up by the trains as their engines, aerodynamic drag and, most of all, braking dumped heat into the air, which became absorbed by the surrounding clay, leading to overheating on the deepest lines.

Why does the Tube not have air conditioning?

When engineers built the tube tunnels back in the late 19th and early 20th centuries, they left no extra space and so there isn’t enough room to install air conditioning units because there’s nowhere for the hot air to escape. As well as this, the clay surrounding the deep running line locks in all the heat.

Why is there no air conditioning in London?

We tend to have a climate where we need heat rather than cooling, so the homes are designed around central heating. Most hotels, shops and office builds work with air conditioning but not homes. If you look at what is needed in a home in the UK it would be double glazing and insulation.

Is there AC in London Tube?

Currently, only the Circle, Hammersmith & City, District and Metropolitan Lines have air con built in to their trains. Although rather shockingly, this adds up to less than half of the entire Tube network.

Why does the tube not have air conditioning?

Which is the hottest tube line?

What are the hottest underground lines? The crowded Central Line is often slammed as the hottest on the network but it’s actually the Bakerloo that could be the most sweltering. In 2019, thermal imaging company Flier predicted the Bakerloo could max out at 42°C, as it more than lives up to its name.

How hot does the London Underground get?

Over the years, the temperatures in those tunnels have risen slowly as the heat-absorbing clay walls have created something like a heat sink. When the Underground was first built, the clay walls were around 14C. Nowadays they are anywhere between 19C and 26C, with air temperatures often reaching 30C.
