Not that you shouldn't use a smoke unit (I do seldom leave mine on for long, though I even like the non-perfumed fluid smoke smell), but it seems to me that a lot of posts here concern themselves with smoke issues and/or even disasters. I'm sure most are fine (like most of our "fancy" electronics are fine), but I have real doubts about what amounts to a near-fire in your locomotives, especially the plastic-bodied ones. I don't think that the house is in danger, but these are delicate machines running around with little electric space-heaters blowing full blast under plastic shells, near other electronics.
This seems ill-advised. It's one of the reasons I don't "smoke" much - and the diesel models now typically smoke far too much, which looks anything but realistic. And it's not black - should be, maybe unless it's an EMD 2-cycle.
We could just imagine that it's smoking.
