Space weather caused a 16-minute train delay in 1848: 'Our research has a hint of a detective story'

On December 2, 1848, a geomagnetic storm triggered an unexpected disruption impacting communication systems across Britain. Specifically, a surge of electrical current flowed through telegraph wires due to this space weather event. This interference directly resulted in a 16-minute delay for a train operating on the Stockton and Darlington Railway line near Shildon, County Durham. Researchers described the situation as having “a hint of a detective story,” highlighting the unusual circumstances surrounding the incident. The team’s investigation focused solely on the immediate effects of the storm's impact on the existing infrastructure at that time.
