Space storms could switch train signals and cause serious accidents

Critical safety equipment in many train systems is vulnerable to disruption by space weather, which could lead to fatal accidents. Space storms can  wreak havoc in some UK train stations.

A number of electrical systems in the railways of many countries, including the UK, are vulnerable to space weather. In the worst case, a red signal could be turned green, potentially causing a deadly train crash, says Cameron Patterson at Lancaster University in the UK.

“You could have disruptions to signalling systems, which are crucial to railway safety,” he says. “We have to prepare for these things now, and getting that message across, I think, is really important.”
