CHAOS has been visited upon already weary commuters as South Western Railway embark on almost a month of strikes throughout December.
Here’s everything you need to know about the walkout, causing 850 service delays.
When is the strike?
Members of the Rail, Maritime and Transport (RMT) union walked out on Monday, December 2.
The strike is expected to last until New Year's Day.
It is the longest stretch of action against a major rail operator in living memory.
They will stop for a brief period around the General Election on December 12.
There will also be no trains as usual on Christmas Day and Boxing Day.
South Western expects to run just over half of its 1,800-strong service.
As a result trains are being cancelled or delayed and a bus replacement service is operating in some areas.
Commuters into London are facing travel hell because of the long-running dispute over guards on trains.
Why have staff walked out?
Members of the Rail, Maritime and Transport union (RMT) walked out over South Western Railway's failure to satisfy their request for a guard on each train.
The RMT accused the company of "dragging its heels" on resolving a bitter row over driver only operated trains.
Talks had been protracted since industrial action was suspended in February, claimed the union.
The union has launched a petition to make it a legal requirement to have a guard on trains to ensure the safety of passengers."
