Hundreds of thousands of rail passengers face misery this week with a two-day strike by guards. The industrial action is over plans to change the role of guards on trains operated by Southern.
Talks aimed at settling the guards dispute at Southern trains broke down a short time ago with the RMT union saying it would "escalate the dispute."
More strike days are expected to be called when the union executive meets next week.
The union say managers "stormed out of the talks" after failing to reach agreement.
