Signal failure suspends Piccadilly Line between Arnos Grove and Hyde Park Corner
The piccadilly line was part suspended this morning between Arnos Grove and Hyde Park Corner westbound after a signal failure at King's Cross St. Pancras. Severe delays hit the rest of the line as London moved into a busy Bank Holiday weekend of travel.
Tickets were being accepted on London Buses, Great Northern, Weaver line, South Western Railway and Elizabeth line, giving passengers other ways through the affected corridor. The disruption narrowed later to westbound service between Arnos Grove and King's Cross St Pancras.
King's Cross St Pancras disruption
The signal failure at King's Cross St. Pancras cut the Piccadilly line's westbound service through central London first to Hyde Park Corner, then back to King's Cross St Pancras. That left the rest of the line running with severe delays while trains through the affected section were reduced.
The timing mattered because London was preparing for a busy Bank Holiday weekend of travel. The RAC estimated 19 million leisure trips would take place by car between Friday and Monday, with Saturday expected to have the heaviest traffic.
Arnos Grove to Hyde Park Corner
For passengers travelling from Arnos Grove, the most direct impact was the missing westbound service through the middle of the line. Hyde Park Corner marked the first limit on the route, then service was cut back further to King's Cross St Pancras.
That left ticket acceptance as the practical fallback across London Buses, Great Northern, Weaver line, South Western Railway and Elizabeth line. Riders trying to cross the city had to choose between waiting for a delayed Piccadilly line train or switching to one of those accepted services.
Bank Holiday travel pressure
The Piccadilly line disruption came after a good service returned on the Northern line following an earlier fire alert at Mill Hill. The Central line also had minor delays between White City and Ealing Broadway and West Ruislip because of a signal failure at White City, while the District line had minor delays between Barking and Upminster eastbound only after a faulty train at Becontree.
With severe delays still on the Piccadilly line and accepted tickets spread across several routes, the clearest move for affected passengers was to use the alternatives already listed rather than wait for normal service to return. Anyone heading into central London had to plan around a westbound gap through Arnos Grove, King's Cross St Pancras and Hyde Park Corner.
