The above title was what I thought when I first heard that there was a smoking diesel in O Gauge.

I only have five of them (3 MTH and 2 Lionel), and only 3  (1 MTH and both Lionels) consistently smoke. Otherwise, all 5 run and sound great, and all are very good pullers.

I don't smoke, but I guess I'm into smoke because smoke is my favorite locomotive feature.

Here is one of my best smokin' diesels in action:

Now IMO this MTH Proto 3 smoking diesel is terrific in every way, except for one thing: it rarely smokes.

I'm still very satisfied with this locomotive because IMO it's a very good runner and puller with great diesel sounds and a great appearance. 

 It was part of an MTH set that I bought new from a LHS several years ago. The only time it smoked well was when the technician at the LHS flooded it with smoke fluid shortly after I bought it.

I've always thought it was better to add just a few drops of smoke fluid to a locomotive, not flood it with smoke fluid.

Today, I first added 4 drops of fluid and got no smoke. Then I added a lot of fluid, maybe one-third of an eye dropper, and still no smoke. 

Anyone have any ideas? Arnold

This MTH proto 1 diesel has always consistently smoked well. I just add 4 drops of smoke fluid at a time until the smoke lightens up, then I add 4 more drops and it smokes well again. Also looks, runs and pulls great.

Love the Jersey Central livery. I also like having it pull oil tanker cars. Reminds me of the NJ Turnpike, which stinks, but I still like it because I have very fond memories of NJ, where I had great childhood vacations with my dear aunt and uncle, long gone. 

Model trains can be very special when they remind you of wonderful times, past and present. I'm sure that's true of many of you. Arnold

I don't switch the smoke in my diesels on because it is the wrong color. Diesel engines emit black smoke from the burning of petroleum. I do switch the smoke on my steam locomotives on because steam locomotives emit white smoke. If they ever invent a fluid that emits black smoke when heated, I'll start using it in my diesel engines.

Yeh...from my non-technical qualification....if white smoke is coming out of a diesel exhaust pipe under load, that engine is on the way out, and about to expire. Dark black smoke from a diesel under load is always a good thing!!!!

Usually, if you manually rev up the diesel RPM sounds, the smoke output increases.  However, if you just let the RPM sounds automatically respond to the throttle speed control, they will probably be simulating low throttle positions.

I have a few diesels with smoke but don't usually run it due to complaints about the smell.

I have a bunch of these little K-line Plymouth's and they can take out the room if I run a few of them at the same time.

I'm planning on adding an exhaust fan over the layout soon.

I can give you the black smoke right now.  However, I am NOT available for the massive cleanup you'll be doing when the black particulate settles on everything around the layout!  The reason you don't see black smoke is that it would have to be particulate matter, and that would make a massive mess!  The white "smoke" is simply mineral oil vapor, while it does settle, it takes a lot of running time for it to be of significant impact.

Black smoke from a diesel is not a good thing. Usually it has a stuck injector flooding the engine with more fuel than it can burn. 

Yeh, that's how we get the "big rigs" to go faster down under.....open the injectors up and wind that pump all the way up!!!!  More fuel in.....more power out. Just don't you worry too much about all that black smoke.
