Overview
- A low-speed collision occurred on Thursday when an out-of-service London Overground train struck a buffer at Liverpool Street, and the driver suffered minor injuries before being discharged from hospital.
- Platforms 1–3 were closed after the incident, prompting widespread cancellations, early terminations and diversions that have hit Stansted Express and multiple regional routes.
- Greater Anglia and other operators introduced short-term measures such as ticket acceptance on alternative services, routing trains to Stratford or terminating at Bishops Stortford, and Delay Repay guidance for affected passengers.
- Further operational problems on Friday included a trespass at Goodmayes that forced engineers to switch off overhead power and block lines, and a police response between Tottenham Hale and Cheshunt that was later cleared but left knock-on delays.
- A formal investigation into the buffer collision is ongoing, Network Rail is assessing repair work needed to reopen the platforms, and passengers have been told to check live updates because disruption may continue into the weekend.
