Mayner, your comments and suggestions really fit well with what I'm thinking at the moment, the attached photo shows how busy this North Cabin view can be. I still meet one of the last shunters still living in Omagh who did all the shunting at the station. I will be able to ask him of the stock that he worked. Using the footbridge and platform ends to block the station is a great idea and I'm grateful for pointing me in the right direction.
