A 48-hour strike is underway on South Western Railway (SWR). The walkout by members of the Rail Maritime and Transport (RMT) union is the latest in a long running dispute over changes to the role of guards on trains.

Around a third of SWR's trains have been cancelled on Friday 5th October and Saturday 6th October. More disruption for passengers is expected on Saturday. The rail firm's Managing Director, Andy Mellors, has apologised to its customers for the inconvenience caused. An amended timetable has been put in place.

The RMT says new figures from the British Transport Police detailing a 17% rise in crime on the railways support its claims that guards play a vital safety role.

The RMT said that four out of every five guards taking part in a survey said they had prevented an emergency situation and used their safety training in an actual emergency. Half of the 800 guards who were questioned said they had prevented at least one sexual assault and 98% said they had dealt with anti-social behaviour.

"In contrast to the cost-cutting plans and misleading propaganda dreamt up in Whitehall and the rail boardrooms, this survey shows the reality of the vital role train guards play at the sharp end to ensure a safe, secure and accessible railway.
