Rail commuters are suffering a fresh bout of chaos today as Southern Railway train drivers begin new strike action.
It is the latest industrial action by the Aslef union in a long-running dispute over driver-only trains.
Thousands of rail passengers have been told not to travel at all this week, with the strike action also affecting Wednesday and Friday.
Many commuters have expressed their anger and frustration on social media.
Southern is providing limited replacement bus and coach services for essential travel from a number of its stations.
