I replaced the old electronics and light bulbs by LED’s. In addition I placed a yellow warning light on the roof top of the locomotive, that is planned to be flashing. For the power supply to the track cleaning waggon I also had to add a power plug at the end. In the front section a insulating screw joint has been mounted to connect the BlueHorse board from BlueRailTrains. I had to construct a little rack to put the BlueHorse board above the screw joints.
