A solid model from Dapol with plenty of scope for DCC sound.
Dapol Class 43* HST DMU
The Dapol HST has a motor at one end and a dummy engine at the other, which means you have options when it comes to DCC sound. With a little effort
you can install sound in the motor coach, and at the dummy end it is quite straight-forward, especially as
the entire space where the motor would have been is available and empty for a SugarCube speaker, so plenty of volume that end.
Either a single sound decoder can be used, or YouChoos can supply a dual-sound pair of sound decoders, with differing engine sounds each end.
Cab lights and crew are also fairly straight-forward in this model, adding a nice little extra feature.
Ideal setup is to use an MX649N direct plugin decoder at the motor end, which plugs directly in, with the only mod required being to cut down the circuit board screw mounts
a little so it sits slightly lower, then a SugarCube7 vertical at the back of the motor car. Dummy with an MX648F (6pin on wired harness), SugarCube9 speaker and a SPEIKOMP
stay-alive kit (which is useful in the dummy to avoid crackles since there is not much weight in there).
