So I belong to the Detroit Model Railroad Club, and recently some of our members have been buying units that are equipped with smoke.
And this brought up the discussion of running smoke. Some of the older members are of course against any use of smoke what so ever. They're reasoning is of course that it leaves a residue on everything and it will cause the rails to rust (we use hand-laid steel rail).
We are in an old movie theater and have at least 20ft ceilings in some places and so the dissipation of smoke is not a problem. The main time we would be doing this is during open houses, as a crowd pleaser. A test was done during one with one locomotive, and the crowd loved seeing the smoke (even though it was a diesel). myself and a few members were talking about just running two or three locomotives at a time for a couple laps (1 lap takes about 20 minutes when running prototypically).
Anyway, I was wondering if anyone has any opinions on smoke, and what your experiences have been. Personally I feel that having smoke adds to the experience.
