@lionel1946 posted:I have the 2-rail version of this loco, and I'm happy with it. The only thing I would change is changing the smoke unit so that it puffs in sync with the chuf sound. As delivered (at least the2-rail version) the smoke is just a weak continuous stream, no puffing. Any suggestions?
I'm thinking the 2-rail version has QSI electronics and the Seuthe smoke unit, it won't smoke you out of the room. Look down the stack, if you see a little rod in the center of the smoke unit, that's the Seuthe smoker. A weak continuous stream perfectly describes how it operates.
