Hey I just finished trying something that worked better then any smoke unit I have, I stopped at the ice house that sells dry ice I removed my smoke stack and sealed the bottom, I then broke little chunks of dry ice and dropped them in the top A lite "Smoke" started coming out it wafted down around the stack looked neat then I added a few drops of water and then the "SMOKE" really started better then any smoke unit, the real payoff comes when you start the loco in motion you get the smoke effect without the lingering bad crap in the air and there is NO mess and it lasted for about 10 minutes Far longer then most smoke units that would fit in the space available. note it does not leave a trail of smoke just the appearance of smoke leaving the stack.
