SOUTH WEST Trains is urging passengers affected by £20m improvement works to have their say through social media on March 25.

The improvement works will see a set of 30 points replaced between Southampton Central and Redbridge, but it means that passengers will have to catch rail-replacement bus services between Southampton Airport and Bournemouth on weekends.

Passengers can quiz South West Train managers about the works through Twitter by using the hashtag #TTMSWT.
