SOUTH Western Railway says it will do everything possible to keep customers moving over four days of RMT strike action.

The walkout, called by the Rail, Maritime and Transport (RMT) Union as part of an ongoing dispute over the role of guards on trains, takes place from August 30 up until September 2.

A South Western Railway spokesperson said: "During strike action, while services are likely be busier than usual, we will do everything we can to keep customers moving.

"We will be running just over half our normal timetabled service over the course of the four days and have rail replacement services and ticket acceptance in place on other transport providers wherever possible.

"We will also look for opportunities to introduce extra services each day to help keep our customers moving so recommend checking the SWR app for the latest travel information."
