I finally got a TMCC Cab Forward blowing pretty serious steam (Mega Steam) -- so much so that it kind of soaked the area around the smokestack! I assumed it was condensed steam fluid - i.e. oil - but I looked at it today (after 24 hrs) and it seems to be gone. Evaporated.
Is it possible that the "wetness" was water vapor? Doesn't make sense to me, but how else could all that steam residue go away?
I'm also curious if anyone has noticed a build-up of oily residue on their track, layout, furniture, etc. if they like a lot of steam coming out of their locos -- does the stuff gradually accumulate on surfaces over time?
Boy, that engine (TMCC Cab Forward) sure is difficult to fill with smoke fluid -- it has a bar that runs right over the top center of the stacks. You need a needle applicator to get the fluid past it, as the eyedropper supplied with Mega Steam just makes a huge mess and much of it did not even make it into the batting -- it was all over the *inside* of my loco. I got all that cleaned up before testing and seeing the boiler soaking -- which may have been exacerbated by the bar over the stacks which blocks some of the smoke coming out. At times it appeared to be "flowing" out of the stack and down the sides of the boiler, as if it were dry ice in there!
Thanks for your thoughts!
