Hornby OO HST with DCC Sound

Kit: Zimo MX645R with Zimo Dumbo LS40X20X08-1W

In the motor coach, we use a Zimo LS40X20X08 1W Dumbo speaker, which sits on top of a plastic bridge which we added above the motor shaft. Lots of room for the 8pin MX645R above the PCB.

Carefully remove the cab interior to add a driver and intercept the cab lights so we can get independent control of the cab light from all the other directional lighting. We use the decoder's GREEN output wire for this.

The dummy coach is easier as there is a lot of room for a larger speaker, although it is useful to add a large stay-alive there because the dummy is quite light-weight in comparison, so benefits from the backup power.

Just the obligatory photo shoot now...
