Railway workers on the East Coast mainline are staging a 24 hour strike today.
Members of the RMT union are taking the action because of plans to cut 200 jobs. Virgin Trains says it will continue to operate a full timetable between London and Edinburgh.
The company says it is making changes to 'customer-facing roles' which will see a single person take responsibility for the customer experience on its trains. It says that will have no impact on safety, and will result in a better experience for customers.
It has also ruled out any compulsory redundancies.
David Horne, Managing Director for Virgin Trains on the east coast said, "The changes we are making are part of the customer-centric revolution we have planned for the east coast. Alongside more modern trains, we want a modern customer service proposition - one that focuses firmly on the customer...we urge the union to rejoin us around the negotiating table."
