A freight train has derailed in south east London, causing major disruption to the Southeastern network.
Thousands of passengers faced delays getting to work as services were suspended and cancelled on Tuesday morning.
Southeastern tweeted shortly after 6am to say the train had derailed in the Lewisham area, adding: "All services through the area will be disrupted, with some services suspended."
The firm said tickets would be accepted on bus routes, Underground services and on other rail and tram services in the area.
Southeastern added: "Disruption is expected to last all day. Please make sure you check before travelling."
