Heljan OO Class 33 Diesel

Kit: MX645R; IceCube18X13X07-1W

Due to the position of the fan assemblies in this Heljan model, there isn't much scope for a larger speaker without modifying them. So we opt for a single IceCube, which is perfectly good for most people's requirements. We use the larger MX645R sound decoder, as the Heljan motor is quite hungry. No stay-alive in this one, but we could have added a SuperCap without too much bother.
