I've managed to get a fair bit done this week. The first thing was to test the 1 metre radius curve, the big question, will the hoppers with protocraft couplers and my coupler boxes go around it. Yes they will surprisingly easily
So using the track templates provided by Oz7mm, I formed the curve and fixed it firmly down.
Above are 2 of the hoppers and a GP35 that has the protocraft couplers too and it all pushes nicely around the curve.
So now I know that works, I think there might be room to fit a turning Y too.
