“We are focusing on supporting colleagues and customers who were involved in the incident and on minimising the disruption this incident will cause to other services. We're working closely with Network Rail and others to understand more about what happened.
"No trains are running between Barrow-in-Furness and Lancaster and there will be significant disruption to our services in this area. Customers should look on our website or speak to a member of our team for more information."
