Services across the south from the Thames Valley to the south coast will be affected.

Work at Feltham junction will mean cancelled services from Reading to Waterloo throughout Saturday and further delays on Sunday.

Further South, work on the tracks will disrupt services between Southampton and Brockenhurst on Saturday and between Southampton and Bournemouth on Sunday.

Buses will replace trains on many routes and travellers should allow extra time for their journeys.

Trains in the area were badly disrupted over the last week due to a combination of flooding and major signalling problems.
