Multiple UK rail services are disrupted following a major power outage affecting National Rail operations. According to reports, National Rail confirms the disruption is caused by an electricity supply failure at one of its communications centres. The outage impacts rail lines across the network, leading to widespread disruption for passengers. The affected services include rail routes identified in outlet mappings that compile which lines are experiencing problems. National Rail attributes the disruption to the communication-centre power failure rather than to an incident on a specific track or route. The outages and resulting service changes vary by line and location, reflecting the extent of the communications disruption. Outlets continue to report the situation as passengers are advised to check live service information for updates, as recovery efforts progress. Overall, the reporting across sources points to a single operational cause—loss of power at a National Rail communications facility—resulting in broader disruption across the UK rail network.
