covered wagon, 1:32 scale
The platform is 230mm long, 262mm between the buffers.
Axle holders are made to fit 3mm shaft. which means that the LGB's wheels and equivalent will fit in these. On these carriers i have done attachment for standard couplers such as LGB and equivalent.
I have little experience of moving axles, but I have been testing it this winter, and it seems to work well. But you need something that keeps the wheels more or less parallel to the tracks.So I have tried with this variant, with a holder in the middle and straps in plastic (such you get post packets wrapped with) it has worked well so far. The holder has two holes of different width to fit the a suitable screw you have available at home.
