London Waterloo travellers affected by signal problems
Thousands of rail passengers faced up to 90-minute delays to their journeys to and from London Waterloo on Monday due to signal problems in two areas.
The first signal problem in Walton-on-Thames, Surrey, shortly before 1200 BST, was followed by a second problem in the Vauxhall area at about 1745 BST.
All services between Waterloo and Woking were cancelled and there were alterations to other services.
Services on South West Trains returned to normal on Tuesday morning.
A South West Trains spokesperson said: "The initial problem in the Walton-on-Thames area started just before noon. That problem was resolved around 2015 BST, however there are knock-on delays which will last until the end of service."
Trains between London Waterloo and Portsmouth were diverted with journey times being extended by up to 30 minutes.
