I too have some parts, but always happy to have more . . . I am building a wheel rack for including in the scene. I have a small chain hoist also in the making to add over a track . . . .
I real intention here is to use the front rear track as my programming track, and the rear rear track for display of in-progress locomotive builds (of which I have too many). The front two tracks are active and live and so will serve to host all manner of stuff shipped in.
