When father downsized in the 1980s I had the task of dismantling my late brothers model railway which I helped build back in the 1960s it had models of just about every railway company. It languished in boxes for a year or so before I rebuilt it at home continuing the freelance BR theme. Gradually I became disenchanted with it and started a major rebuild based on Peak Forest 1948/1968, the more I read about it, particularly in Mr Bentleys books, the more it appealed. I can still legitimately run a wide selection of models as Derby used the Derby-Chinley-Derby as a test route (amongst others) and it's not far away with the mainline through Cheadle Heath is on my doorstep where I saw all the CoBos when they were new and I was still at school. Yes I have a soft spot for the CoBos, and those hopper wagons, the Fell, etc.
