Workers on South Western Railway have voted heavily in favour of striking in the dispute over the role of guards on trains.
Members of the Rail, Maritime and Transport union backed walkouts by 4-1 on a turnout of 76 per cent, well above the 50 per cent threshold in the Trade Union Act.
The company only took over from South West Trains in August, running services to and from London Waterloo, including the Portsmouth area.
It is now the fifth rail operator to be embroiled in a dispute over the role of guards and driver-only trains.
RMT members at Southern, Merseyrail, Arriva Rail North and Greater Anglia were said to be ‘solidly supporting’ a 24-hour strike today over the same issue, with another stoppage due on Thursday.
Picket lines were mounted outside stations, including in Manchester, where the Conservative Party conference is being held.
