Here is one of mine. MTH Proto 1 Jersey Central FM Trainmaster:
Paradoxically, although I am not a smoker, I love model train smoke, both for steam and diesel locomotives. I usually use Pine scented smoke fluid, both Lionel Premium and MTH.
Another favorite scent of mine is cedar, though I have never gotten that one, but hope to get it soon. I think Mega Steam makes it.
So let's see one of your favorite smokin' locomotives, and tell us about some of your favorite smoke fluids. Also, let's not forget those old fashioned smoke pills and the Postwar locomotives that used them. Arnold
