Heljan class 45 fitted with a Zimo MX696KS decoder and loaded with a YouChoos sound project.

A Heljan class 45 fitted with a Zimo MX696KS sound decoder through a pair of speakers. It is a YouChoos sound project but I've altered the function outputs to operate directionally. So F0 operates the forward and reverse markers. F10 operates the tail lights dependant on direction and F20 operates the cab lights, again dependant on direction. Zimo decoders are excellent for these type of adjustments.
