Wiring up a model train layout in DC (direct current) is a great way to keep costs down and learn some basic electronics. We examine our wiring diagram and explain how triple pole double throw switches are used to power the trains and bipolar LEDs.
Making an adjustable table
The legs of our model train layout table are height adjustable. The lower table height is set for seated viewing like a coffee table. When the table is adjusted to the high position it makes viewing comfortable while standing. The higher position is also used when working on the layout. In either position the adjustable table has a drawer which slides out for access to the control panel.
Why not sell it all?
Is it possible when we talk to our parents we talk only about the extremes in our lives? Boast about our proudest moments or complain about the things that bother us? Do we filter out all the middle bits and present an unclear picture of what we enjoy most about every day life?
I’ve certainly complained a few times since starting our N scale model train layout. For one thing it’s taking way longer than I expected. And it’s certainly a lot more difficult than I anticipated. The boys see other amazing layouts and wonder why Dad is taking so long. But if these complaints were the tip of an iceberg then what lies beneath is an entirely different picture. Continue reading
Building the control panel box
We’ve built a wooden box to contain all the lights and switches for our N scale model train layout. A 3mm clear perspex face plate sits on top of the layout schematic. LEDs and switches will protrude through the face plate and all the wiring will be containing inside the box under a hinging lid.
At this stage we haven’t decided whether the box will slide out on drawer runners or be a separate attachment to the model train layout. Either way, the loco speed controllers will plug into the front and the wiring loom (including power source) will plug into the back of our control panel box.
Control panel design
This design will sit beneath a sheet of clear 3mm PVC. The PVC has holes machined for switches and lights. The overall size of the control box will be 210mm x 297mm. The strategy for A4 size was for easy reprinting of the design. The PVC will be supported on a frame with 9 screws that can hinge open for wiring access.
