A five-day strike that workers on Southern Railway are "solidly supporting" will cause travel misery for hundreds of thousands of passengers.
As the strike starts, members of the Rail, Maritime and Transport (RMT) union have walked out. They're mounting picket lines outside stations in an escalating row over the role of conductors.
Southern: "We don't need conductors."
Conductors: "We're going on strike"
Southern: "Cancel the trains! We need conductors!" #southernstrike

I have never even seen a conductor on a Southern Train. Clearly aren't that safety critical. #southernstrike

Southern's owner, Govia Thameslink Railway, apologised to passengers, describing the strike as "completely unjustified".
Some parts of Surrey and Sussex will have no trains at all because of the industrial action.

RMT general secretary Mick Cash said: "The strike action this morning is rock solid across the Southern Rail network as we fight to put rail safety before the profits of the failed Govia Thameslink operation.
"This action has been forced on us by the arrogance and inaction of Govia Thameslink and the Government, who have made it clear that they have no interest in resolving this dispute or in tackling the daily chaos on Southern."
Obvs passengers are taking to Twitter to discuss how the strikes are affecting them. And while they're not exactly happy about the situation, they're saying it's not much different to normal TBH.
The irony of the Southern Rail Strike is that the usual service is so bad that I genuinely can't tell the difference.

Feel more than annoyed at listening to the CEO of Govia apologising for the inconvenience "this week". It's EVERY day mate. #southernstrike

Southern Rail passengers have been told to expect a disrupted service of late & cancelled trains today. Or "Monday" as they usually call it.

Yeah, people are pretty frustrated with Southern Rail right now.

#southernstrike I'm pro-strike but is that five days in a row? Because that is outrageous if it is - should be two at the most.

They don't really understand how the strikes are about safety.
Passenger safety?? Right, of course. So packing double/triple the amount of people onto the only trains running is safe? #southernstrike

An emergency timetable has been put in place, with Southern saying it will run 60% of services. And ironically, some people are saying this reduced service meant their train was on time for a change...
Well at least my train has arrived as scheduled. #southernstrike

Ironically, this week will be the first week that all the trains were on time. Because there's only about 7 running. #southernstrike

Of course, some tweeters are sticking up for the workers who are striking.

Hey, at least there's time for crosswords...
