London’s transport network disrupted by power outage

London’s underground transport faced significant disruptions on Monday due to a power cut from a fault in the electricity grid, affecting thousands of commuters during peak hours. Key train lines, including Jubilee and Waterloo & City, experienced delays and suspensions, highlighting vulnerabilities in Britain’s infrastructure, particularly after a recent fire at a substation led to Heathrow airport’s closure. The National Grid reported the fault was resolved quickly, but Transport for London faced ongoing delays, exacerbated by outdated IT systems and signaling equipment that required testing before resuming services.
