The first of the 2 whirlygig 360 degree fiddle yard trays (to allow turning of a complete train) now have some track down. The sides have now been laminated with ply. The individual tracks will be lined up to the layout with brass tube and L shaped pins in the time honoured manner, these will also provide electical continuity - simple. Once that has been done and the plywood sides added to the baseboards, the whole lot will be sprayed black to match the rest of the layout. To stop stock falling onto the floor, foam covered plywood safety plates (not seen here) engage between the little keepers seen on either end.
