A photo of the underside of the layout segment that will have scenery applied to it. This shows how the aluminium is employed but it also shows the wiring of the various components. The power and DCC control system will be fed into the layout from under the centre section of the layout so all wiring heads toward the plug point at the right hand end. I’ve gone to the trouble of allowing for future expansion by drilling an extra hole for the sockets I use to connect the modules. This will allow for easy installation if this is required later.
