South West Trains hit by 'major power failure'

The power failure affected trains across the whole South West Trains network

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.
