Overview

• Engineers repaired the faulty routing equipment late on July 21, enabling all 14 platforms at London Waterloo to reopen by the morning of July 22.
• Most services have returned to their normal timetables, though long-distance routes to Exeter St Davids, Portsmouth and Weymouth still face sporadic delays as trains and crews are repositioned.
• During the outage, SWR accepted tickets on alternative CrossCountry, Southern, Great Western Railway and bus services at no extra cost and extended ticket validity to July 22.
• Monday’s incident followed a series of mid-2025 signalling failures across London’s rail network, underscoring ongoing infrastructure challenges.
• SWR, renationalized in May 2025, now faces heightened public scrutiny over maintenance and reliability under its new ownership.
