Southern rail services are set to be disrupted tomorrow (Tuesday April 26) and Wednesday April 27, due to a strike by RMT union members.
Services into London Victoria and London Bridge will be reduced, with trains expected to be "very busy", and there will be no Southern service on the line into Ashford International.
Lines along the south coast will also be affected, with services either cancelled or "significantly reduced".
