Rail passengers in Southampton are facing delays of up to an hour after an electrical problem.

The issue with the electrical supply has affected signalling in the Basingstoke area.

Trains were unable to run for around 25 minutes, but have now started moving again.

South West Trains said disruption is expected to hit passengers travelling between Weymouth and Farnborough as a result.

Some trains will face cancellations and revised times.

The operator said it hopes to have normal services resumed by 8pm.
