Cheers Tom, the plan is to model the Cork yard and main station condensed and in two halves to form a loop. I have an attic space 5.5m X 4m and I'm planning to build the yard with shed and cement works on one side and the main station on the other. I've been playing about with some rough track plans but nothing fully worked out yet. At the moment I'm concentrating on building the various structures for the layout. I've insulated the attic and the next step is to build the base boards.
