Okay I switched gears tonight and did some more On30 modeling. I made an effort to hide the decoder and electronics that is stuffed into the fuel bunker by painting the purple decoder and its wires flat black and added a black deck with a wood load covering it. Not perfect but I'll get an O scale figure to stand by the decoder to help hide it a little better. I'm dropping the idea of switching to a smaller TSU micro decoder and I'm going to call it "good enough" and move on to adding some handrails, grab irons, couplers and weathering.
Painting did help. A figure or two in that cab, plus maybe some clutter and perhaps it will barely be visible.
