This is how our cars are constructed. Warrick Sandberg's bogies.
Simple frame - 25x25x3mm side rails, 75x10mm bolster support, 50x50x3mm buffer bar/ends, 20x20x3mm corner supports.
Sides are one piece with 20x20mm top fold, 245mm high side, 100mm footboard with 15x20 folded edge. This is Car#2 with 1mm steel sides and ends... I have ditched the handles on both - just as easy to grab under the ends.
Lights and cabling to go... Both cars are directional, having the brake pedal only on the driving end of Car#1, and Car#2 also has only one braked bogie - which should be on the front for effectiveness. So red lights only need to be on one end - of each!
