The Design of Thermal Tunnel Energy Segments for Crossrail

In recent years the drive to reduce carbon emissions and reliance on oil and gas has led to the increase in the use of renewable energy heating systems. The ground source heat pump systems are an example of these renewable systems. Recently tunnels have been considered as a way of connecting buildin [...]

Tunnel Energy Segments

Significant heat is generated by underground trains, particularly when braking, stopping at platforms and accelerating away from stations. A complex ventilation system including shaft, fans and under-platform extraction  has to be designed to manage the rising temperature in tunnels and stations. T [...]
