I've been giving this challenge a lot of thought, perhaps too much, as I've come up with five ideas so far, but then, I'm in good company as I think Stubby is ahead of me on this. Ideas which may yet see the light of day include a partially sectioned railway goods warehouse, and construction of Nottingham Victoria station!. This last idea got club members excited when I mentioned that a steam shovel would be a necessary part of the diorama, and they envisaged giant size fireman's breakfasts cooked on it!
But the one I'm going with is distinctly conventional, compared to some of the inventiveness being shown by others. Quite simply, I'm going to make a model of Boscarne Exchange Platform with its two sleeper built halts, two tracks and associated signal(s), fencing and lights.
A quick assembly of bits and pieces to hand proved that it is feasible in 4mm scale. And so to work (but not before I've knocked up a 'quickie' for our club's intended display of cakebox challenge ideas at our exhibition in four weeks time!).
