London's transport network has faced significant disruptions due to technical failures and fatal incidents. On October 23, a power outage caused by a National Grid transmission fault in central London led to the suspension of multiple London Underground lines and the closure of several stations, including Waterloo.

Following this, major rail corridors experienced further instability. A fatal incident at Hanwell station resulted in the closure of lines serving Heathrow Airport, Reading, and London Paddington, affecting the Elizabeth line, Heathrow Express, and Great Western Railway. Additionally, a signal fault between London Waterloo and Vauxhall caused delays for South Western Railway services to various destinations, including Portsmouth Harbour and Exeter St Davids.
