Two other things about smoke, if you DO have a smoke unit in the engine you eventually choose, it is kind of a "use it or lose it" proposition. Basically it is an electrically operated burner, so if you just add smoke sporadically, you run the risk of burning up the smoke unit. In other words, you have to keep oil in it and keep using the smoke unit or risk losing it for good. Not a bad thing if you decide a smoke unit is for you, just a heads up.

My understanding is you can turn the smoke unit off and on through the DCC control. You can also adjust its output.

I think it may end up being this engine... Its not my first choice as far as looks because it doesnt have all the open detail look I want but it does have the smoke, the sound, the dcc, the correct road name, the nice color and shine I would want in a restored engine. Hell, it even has the correct area.... Is it a for sure deal, not yet. Is that one in the lead. A definate YES!
