I have inherited an N-Scale, 4x8 layout, unfinished and in disrepair from my grandfather and will be slowly disassembling it and transporting it across two states. I only plan to keep the track and the structures, as the plywood, foam and cork on the original layout have attracted the smell of the garage it was kept in. There are two levels to this layout, both currently controlled by separate DC controls. When I reassemble this, I would like to convert to DCC. Any wiring help would be great! Will I need two separate controllers for that? Also, when I reassemble this, I would like to "fix" any problem areas, maybe make it a little more realistic. Whats the best way to clean track of grime and dust? I am open to ideas. Thanks!
