Due to space constraints, I run N gauge. Here is a picture of my Alaska Railroad passenger train. As you can see all cars have lighting. The cars are a custom paint job from a VIA Rail carset by Con-Cor (minus the business car). All have plastic bogies, plastic wheels and plastic axles. The power comes from the 2 GP-38 and the couplers. I use 2-pole electrified magnetic couplers, that’s enough for running analog. The same company, PeHo, also has 3- and 4-pole electrified magnetic couplers in N– and H0-gauge. Thierry from Switzerland
