Commuters are experiencing heavy delays between Weymouth and London Waterloo after a "medical emergency" onboard a train.

The 5.45pm South Western Railway service remained stationary at Parkstone for about 40 minutes having arrived shortly after 6.30pm.

One passenger on board the train said an announcement had been made asking if there were any medical professionals onboard the train that could help.

Delays resulting from the incident are expected to continue until 9pm this evening.

Further delays across the SWR network have been experienced tonight with police attending an incident between Havant and Hilsea - causing a knock-on effect.
