South West Trains hit by 'major power failure'
Thousands of rail passengers had their journeys disrupted on Friday following a "major power failure" on South West Trains from London Waterloo.
All services were affected after the "wide-spread loss of signalling across the network".
For a time no trains were running between London Waterloo and Woking or Dorking.
A spokesman for South West Trains said the issue was resolved by the close of service at about midnight.
In a separate issue on Saturday morning some services to and from London Waterloo were being affected by an electrical supply problem to the level crossings between Barnes and Richmond.
As a result, some services were being diverted or cancelled.
Travel information updates are available on the operator's website.
