Another 24-hour strike will affect train users on Southern rail.

Rail union RMT confirmed guards and drivers on Southern rail, whose services operate from Watford Junction and Harrow and Wealdstone into London, will strike for 24 hours on July 10.

RMT general secretary Mick Cash said: "RMT members on Southern Rail have been fighting for safety and access for well over a year now.

“The franchise continues to lurch from crisis to crisis as the real impact of hacking back on safety and access hits home. "We have seen absolute chaos at Victoria and East Croydon this week in the hot weather which has reinforced the need for safety critical staff on our trains and platforms.

"The government cannot spin their way out of this chaotic situation which is wholly of their making."

Mr Cash says it is down to Southern, Govia Thameslink Railway and "contract holders" to start serious talks to address the issues.

As well as this strike, ASLEF union members will be introducing an overtime ban from June 29, affecting Southern and Gatwick Express lines, which also includes the line running through Harrow and Wealdstone and Watford Junction to Clapham Junction.

The ban will continue until further notice and also affect services through to Brighton, Southampton and a number of lines in south London.

A spokesperson at Southern rail said: "“Once again the RMT is refusing to play its part in the modernisation of the railway.

"Southern is the most congested network in the UK with passenger numbers into London doubling in just 12 years, so modernisation of infrastructure, trains and working practices is essential to provide the service levels passengers need and deserve.

“While we have been willing to negotiate and have made four comprehensive offers, the RMT has not demonstrated any serious intent to resolve its dispute.

The spokesman also says GTR have put four deals to the RMT, who have not presented these to their members, the latest of which they believe "offered guarantees on job security, staffing ratios, rostering and enhanced training."
