Rail workers are “solidly supporting” another strike in the long-running dispute over the role of guards on trains.

Members of the Rail, Maritime and Transport union at South Western Railway walked out for 24 hours on Saturday, disrupting services, including those to and from London Waterloo.

Some services were cancelled and buses replaced trains.

Talks aimed at resolving the row broke down last week, leading the union to call more strikes in the coming weeks.

RMT general secretary Mick Cash said: ‎”RMT members are standing rock solid and united again this morning across South Western Railway in the latest phase of the campaign to put public safety, security and access before private profit.

“RMT is angry and frustrated that efforts by the union to get an agreement on the guard guarantee with South Western Railway bolted down this week was met with the same old tired response from the company that refuses to move the process on and address the fundamental issues.

“That is no way to treat a serious dispute that will impact on huge numbers of passengers through into the autumn and SWR need to get out of this bunker mentality.

“Instead of winging it on passenger safety today, and misleading the public on the level of service, the company should be round the table working out an agreement that ‎puts safety first.

“Our members are striking today to put public safety before private profits and it’s about time SWR took note of what is going on elsewhere in the rail industry, and the settlements RMT has struck that underpin the guard guarantee, and started talking with us seriously around a similar package that puts safety, security and access to services top of the agenda.”
