This topic could also apply to Lionel Tips-n-Tricks. If any of us believe that there is a different proper protocol for Lionel smoke than for MTH smoke, then we can run a similar thread there too.
So, why am I raising this subject?
First, MTH PS3 locos run on DCS are my favorite locos and their smoke feature is my favorite feature. I admit I'm more than a little weird, but believe I'm not alone when it comes to MTH PS3 and smoke.
Secondly, IMO, if the proper protocol is not followed, the smoke feature often breaks down and is lost.
So, if you're interested in this subject, what protocol do you follow to keep your smoke healthy and well.
I will share my protocol later. Arnold
