The Tomix “Yumekukan” is a fun model. The highlight is the three unique coaches at the end: One very first class sleeper, one lounge car, and one dining car at the very end. Last year I installed a decoder into the baggage car; today the dining car (OSHI25-901; オシ25-901) is the focus. The dining car has working table-top lamps, direction-sensitive marker lights, and a lit drumhead: All powered by a very tiny, all surface-mount circuit board that defies dissection. Read on to see how I used a TCS Z2 to convert this carriage to DCC.
