Severe Train Disruptions Force Operational Collaboration Between Network Rail and Govia…
What happened
Operational collaboration is underway between Network Rail and Govia Thameslink Railway following severe train disruptions across Sussex. The issues began after a three-carriage train derailed near Lewes on August 13, 2026, leading to an ongoing investigation by the Rail Accident Investigation Branch (RAIB). Rail executives stated that the region's record hot and dry summer caused the clay soil beneath the tracks to shrink, crack, and warp, compromising network stability. Due to this, Network Rail has implemented temporary speed restrictions, altered timetables, and widespread cancellations, with repairs expected to last until at least the week commencing October 12, 2026.
