I have some HO trains without it but some of my 3-rail trains have it. Do any of you run your HO trains with smoke? Is it even available? Would you even want to? I would guess that there isn’t any for N or Z scales.
Seuthe makes several smokers that can be installed into about anything except maybe a Z scale tank engine. I use their #117 smoker in smoke stacks and chimneys and love them. I do diesel and keep good rings and injectors in my units so they don’t smoke and pollute the air. Most the HO steam locos with smoke are older and not real good runners, but it would be easy to install a smoker and hook it up to a channel on a dcc decoder to smoke. You could also build a timer module to puff it? FRED
Some of the Mantua Steamers came with a smoke unit. What I have done is use strips of cotton, 4" long twist it,hair spray it, dye it with diluthed india ink/alcohol and shove it in the smoke stack.
Also works in chimneys. Cheap enough & pollution free.
Old Bachmann Plus 2-8-0 consolidations have factory smoke units. Mine works pretty well. I’ve got the headlight wires to be constant on, and turn the smoke unit on and off via the headlight function on the DCC decoder. I’ts a real crowd pleaser at club shows.[:D] They still can be found at trains shows, new in the box for a reasonable price.
Heck, what ever happened to making some home made modifications. All a smoke unit is is a small brass pipe with micro wire wrapped around it. You put it in an insulated tiny cup. One end of the wire goes to “+” and the other to “-”. Add a little smoke fluid and your golden. The wire heats the the pipe, pipe boils liquid…puff SMOKE
