I like my steam outline locos to smoke whenever they are in service......okay, so they aren't pulsed smoke
units that belch out as much smoke as a KM1 model, but the 24 volt units I have fitted to most of my locos give out a satisfactory amount.
Some of the loco's smoke units are permanently wired to track power, so if they are on the track they smoke.
If, for some reason, I don't want a loco to smoke, I just fill the smoke unit to the top, job done......then if I want it to smoke, either run it for an hour, by which time the heat has evaporated some off, or syphon a little off the top with the syringe (I used to use for my steamie Regner Stainz).
