putting lights into waggons

Putting some light into the wagons today. As you may know, I have a simplified power supply (18VAC / 6 Amps). So I had to add a bridge rectifier, a electrolytic capacitor and a voltage regulator into each wagon. The advantage is, that result is pretty nice and stable power supply for the LED’s, I build in. My personal goal is to hide all components as good as possible. The rear lights are 12V read LED’s. The interia lights are warm white candle lights.
I also had to exchange the axises from ordinary plastic to metal with power collectors. I replaced both axis and connected them in parallel for a better connection to the rails.
