Once you start hacking @ brick, that leads to crazyness...
Like, 7 LED's on seperate channels of DCC, and a 4 cylinder "engine" driven by a 9V gear motor in the Maersk loco, with 2 DCC chips to control it all. 3mm LED's will fit in the rod sized holes, but there are still places I had to glue/drill lego to make this all work.
LED's are arranged as 2x ditch lights (fwd only), 2x headlights (fwd), 2x headlights (rear), 1x cab light. All wired to .1" connectors, to allow the whole lot to be disassembled. If I had another 9V motor to hack & slash at, I would have 2 9V motors powering, but at present I only have 1.
