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.
Why is the Central Line so warm?
Source of the heat
The heat in the tunnels is largely generated by the trains, with a small amount coming from station equipment and passengers. Around 79% is absorbed by the tunnels’ walls, 10% is removed by ventilation, and the other 11% remains in the tunnels.

Why do tunnels get hot?
But the heavy, dense clays and chalks that supported the construction of so many tunnels in the region are also remarkably good thermal insulators, which means they hold onto a lot of heat.
Which underground line is the hottest?

Why are London subways so deep?
Building underground railways so close to the surface proved to be a very expensive exercise and it was realised that considerable costs would be saved if new tubes could be built at a deeper level, where they would involve much less disruption to existing buildings and services.
Why do tunnels give me anxiety?
Turns out, people do drive more slowly in tunnels. Part of that has to do with perception, said psychologist Roberta Klatzky of Carnegie Mellon University. She said tunnels can be disorienting, making it seem you are driving faster than you are. There’s also the fear factor.
Why do people slow down before tunnels?
Experts say there are psychological and perceptual reasons that many drivers hesitate at tunnels. “Some people who are nervous about confined places and dark places respond to that nervousness by slowing down,” said Mark Scerbo, a psychology professor at Old Dominion University.
How hot is too hot for a high tunnel?

Temperatures much higher than 85°F day/75°F night can stress tomato cultivars and result in flower abortion, pollen sterility and ripening disorders (Table 1).
How hot is the Earth 1 mile down?
Geologists calculate that, for every mile you dig beneath the Earth’s surface, the temperature rises 15º F and the pressure increases simultaneously at a rate of about 7,300 pounds per square inch. Violations of the 15-degrees-per-mile rule are unknown and constitute the notorious forbidden zone.
