Solar Storms Threaten Chaos on UK Rail Network

A new study warns that solar storms, a form of space weather, could pose a serious risk to the rail signalling system in Britain. These storms have the potential to switch train signals from red to green, potentially causing delays or even accidents. The researchers found that space weather events capable of triggering faults in the rail signalling system occur in the UK every few decades. They urge the rail industry to consider the risk of space weather and implement measures to mitigate them, similar to other industries such as aviation and electricity generation.
