Passengers for London will have to change at Reading

It says �8m of track repairs between Reading and London Paddington being carried out by Network Rail has resulted in the reduced service.

From Saturday until 27 August, only two of the four lines between Paddington and Reading will be used.

This means there will be fewer trains running each hour to and from Chippenham, Swindon and Pewsey.

Over the bank holiday weekend there will be no services to London Paddington.

Passengers will have to change at Reading for London Waterloo.

Tim Bowcock from First Great Western said the operator was doing what it could to make things as easy as possible for customers.
