Originally the NextGen controller was ment to control the old Roco NextGen decoders. I managed to get some of those decoders and build one in the Piko Taurus. Also equipped it with led lights and must say that although it’s a loco from the hobby range, they did a perfect job on it. Just for fun a video of the BR182 with a diesel engine and the original sound.
