Fairly simple to add DCC sound to Heljan's Class 128 'Parcels' model. Using YouChoos' Class 108 variant project specifically for the Parcel service where passenger sounds have been removed and sounds for sliding doors added.

The photos here show a Zimo MX644D sound decoder with YouChoos Brick11 speaker, but we'd suggest an IceCube18X13X11-1W speaker now instead.

NOTE: All of the 128 DPU models that we've come across are lacking any dedicated connection pads or sockets for a speaker, so you will need to solder wires for the speaker directly to the decoder, or to the feet of the corresponding pins in the model. If this is too tricky for you, you can request that YouChoos adds these wires to the decoder when you order the kit.
