Furious passengers have endured hours of delays today after a three-day conductors strike on Southern Rail coincided with overrunning engineering works.

Southern Railway services were already reduced by more than a third because of a three-day walkout by members of the Rail, Maritime and Transport (RMT) union.

But the engineering work between Brighton and Gatwick Airport has also meant trains were cancelled or delayed by up to an hour.

Video filmed by ITV News at East Croydon station this morning showed passengers scrambling to get on to any available train. Some commuters told us the situation there was becoming 'dangerous'.

Both sides have blamed each other for the ongoing dispute, which revolves around planned changes to the role of conductors on board trains.

Southern have tried every dirty trick in the book to try and turn the public against the frontline rail staff whose only crime is standing up for safety on our railways while the parent company, who have dragged the GTR services through the mud, are hoarding £100 million in profits.

This [engineering work] adds to the frustration passengers are experiencing today because of the RMT's strike action, which is totally unnecessary now the union has told its members to accept the changes we have planned to improve customer service.
