As global temperatures rise, subways and trains are becoming increasingly uncomfortable for passengers. Researchers like Jonathan Paul are exploring innovative ways to cool these systems, such as using groundwater as a refrigerant. Chris Baraniuk, a Wired Science contributor, highlights the growing challenge of overheating in underground transport networks. The problem is not limited to London, with commuters in Japan and Morocco also facing similar issues. Ensuring public transport remains comfortable during heatwaves is becoming a global priority.
Key facts
- Temperatures in London Tube stations can reach up to 42°C, which is dangerously hot for passengers.
- Groundwater at around 10°C is being tested as a refrigerant to cool underground stations.
- A prototype system using water from subterranean rivers is being tested in a chalk quarry near Reading.
- Train operators in countries like Egypt and Bulgaria are adopting air-conditioning to combat rising temperatures.
- Passengers in Japan and Morocco have reported discomfort due to insufficient cooling during heatwaves.
