Bachmann Spectrum vs DCC On Board- Steam Locos

It was brought to my attention that older Bachmann DCC On Board Steam engines USED to smoke, but now they don't. So I was wondering if the Bachmann Spectrum Steam locomotives smoke at all. I thin that the magic of steam engines is killed off when you take something out that is sooo elemental for steam engines- THE SMOKING effect. Does anyone else agree with this?

Smoke is generated by burning a special oil and it has undesirable long term consequences for the layout.If you don't mind cleaning tracks all the time and having an oily deposit on scenery...go for it.Indeed,a smoker is fun to see but I don't want any on my layout.

it dries out on the road bed, so It doesnt bother me at all. Besides, in the real world, oil is dripped all over the place. But what I was asking is if the Bachmann Spectrum steam locos do any smoke puffing at all compared to the DCC On Board, which no longer do.

That oil is just mineral oil basically the same stuff that cleans your clippers so if it does fall on your track and have a cleaning car there isn't any harm being done.

The few that I have are all spectrum and I guess with a less sophisticated electrics it's the only way you will find one with a smoke element?

Well, i want a steam loco that smokes, otherwise there is no point in having them. But don't get me wrong, I am still keeping the ones I own now, i am just disappointed that
Bachmann removed the smoking units from the DCC On Board steam locos -_-

I'm sure you can add dcc to your existing ones and if I was you I would find the last model year that came out which smoked and just add whatever you desire

Smoke an DCC are not very friendly together!
Smoke units require a fairly large amperage to work and DCC decoders only handle small loads on the function outputs.
There is 3 basic ways to deal with this problem.
#1 Add a relay to the function output, down fall to this is it's on full or off no variables.
#2 Add a second decoder with the second decoders motor output controlling the smoke unit, The input power to the second decoder is controlled by a relay that is controlled by the first decoders function outputs.
#3 Add a optic isolator to the motor output of a decoder and use that to drive a transistor circuit to control the smoke box!
