Southern Trains says it is planning to run 60% of services today as strike action gets underway.

Members of the Rail, Maritime and Transport (RMT) union walked out from 11:00 BST for 24 hours.

In a message to passengers, Southern said: "You may have a long wait before you are able to board a train. Unfortunately we cannot guarantee to get you to your destination."

Southern is reporting a good service on the Brighton Mainline and Gatwick Express. But it says there's partial closures on the rest of its lines. 

There was standing room only on this Gatwick Express train this morning as it headed to London Victoria.
