The driver of the bus takes a wrong turn and loses virtually all of the vehicle's roof after hitting a railway bridge.
A double-decker bus nearly sliced off its roof after crashing into a railway bridge when the driver took a wrong turn.
No passengers were on board at the time and the bridge was not damaged. Rail services were unaffected.
A TfL spokesman said the accident was due to "human error" and that the driver was "a bit shaken up".
Mike Weston, TfL's director of buses, said: "At around 13:00 an out-of-service route 131 double-decker bus, operated by London United, hit a rail bridge on Coombe Road near Norbiton station after taking a wrong turn.
"The bridge was not damaged and rail services are unaffected. There were no injuries and the incident will be fully investigated."
