Quite a simple install, here we have a 3-coach Bachmann 108 DMU, into which we've added DCC sound to the motor coach, and
function decoders to the other 2 coaches to provide lighting.
The primary decoder is a CT SL51-4 with 8pin plug, and a huge 28mm round Zimo 1W/8ohm speaker with as tall an enclosure as we
could get in. The seating area has had a small modification to accomodate the speaker, but it is worthwhile, as the resulting
sound is huge and full!
Into the other 2 coaches, we've installed CT DCX33 decoders, which are function-only, with a small stay-alive capacitor in each
to avoid flickering. Passenger figures have been added throughout, as well as drivers and working cab lights.
...and the finished article...
First, we install the MX685 function decoder in the dummy coach... these come with wires-only normally, so we have added an
8pin plug to make it neat.
The MX648R plugs straight in and sits neatly in the recess provided on top of the motor block. The small Dumbo is wired up, so
we just need to create some space for it in the seating area.
Still sitting too high to get the body back on, so make an aperture in the seating plastic floor so it can sit slightly
