TRAIN passengers on the London Waterloo to Weymouth line are being warned of delays due to a signal problem at Dorchester.

South Western Railway said the issue occurred near Dorchester South station and is causing trains to run at reduced speed on all lines.

Train services running through the station may be cancelled, delayed or revised, and disruption is expected until 7pm today.

Passengers are advised to speak to a member of staff or use a station help point for more information.

Those who would prefer to use local buses to continue the journey are being told to check Traveline - however South Western Railway tickets are not valid on local buses unless stated.
