Open frame test track baseboard Pt5

I fixed the corner braces to to the top corners, hoping that they might make the unit less prone to twisting but they don't make much difference. So I might omit them from future versions.
To give an idea of the amount of twist in the unit: If I lift one corner off the ground then I get about 2cm deflection before any of the other corners also start to lift. The worry with that is that it might be enough to crack scenery or cause fittings to become detached.
I suspect that cross bracing across the entire unit would stop the twisting - and of course a track bed will do exactly that. In the interests of lightweight construction it might be OK to allow a small amount of flex in the base units and rely on the track beds, risers, backscenes and other superstructure to stiffen them up.
So, the next job is to attach a track bed and then re-assess the flexing. I made a start on that:
I also made a loco cradle to help with servicing delicate steam locos. Hopefully the foam will grip the model without crushing or bending details like handrails and whistles...
