Not being much of a designer, have settled on one of Iain Rice's published plans that, with a bit more space available, I have stretched slightly to fit my 14' x 9' garden shed. Fully insulated with strengthened floor, and professionally installed electrics I am now starting to install the baseboards. Solid top down one long side with 8 storage lines, this will have a lightweight baseboard above it to carry higher level branch terminus. The layout will represent a South Wales coal carrying line with a junction to the high level with small coal mine, foundry, station and townscape.
I am experimenting with KD couplings worked by neodinium magnets disguised as sleepers, and the new DCC Concepts under track magnets to assist trains up gradients.
Now back to the L girder open top baseboards for the rest of the layout.
Photo's to follow.
