Longest ECS movements?
Having just seen paths for an empty coaching stock move for an IET from Westbury all the way back to North Pole IEP Depot near London got me thinking - what are the longest ECS moves on the schedule? I'm defining an ECS move as moving from a service to depot rather than a move between depots.www.railforums.co.uk
