Has anyone installed a Soundtraxx Tsunami micro in a 0n30 Climax? It has a little less room than the Shay. I have the older PNP Soundtraxx unit installed currently, but without a stay alive capacitor it is not the smoothest runner. I am curious about installation room (plan to used wood load > space) and how the decoder was insulated since it does not come with a covering?

When using the provided San Juan decals on the Bachmann 2-8-0 modified  by Soundtraxx with sound is a gloss coat required before applying the decals for best results or is the as received finish acceptable?
