Model Train Lighting

One thing that’s still always very irritating with model train setups is that the locomotive or carriage lights often flicker with the train passes over a turnout or a bad section of track. This simple circuit can put an end to this. Even better, it ensures that the lights burn at a constant brightness (within certain limits), regardless of the speed of travel (which means the voltage on the rails), and the lights remain on when the locomotive is stationary for a while.
