I need to know the overall height of the Consolidation 2-8-0 with either stack installed.  Anybody know?

Has anyone had experience and can recommend a smoke generator for O scale buildings?   I've tried Seuthe, but only 1 out of 6 or 7 actually work, and then for a very short period.  I have an extensive layout, and would like to find a quality smoke generator supplier.   Thanks,           David

Thanks, Harold.  I thought I had screwed up, as I have sent the loco to have the decoder installed without checking on the radius problem.  Now I can relax   David

What is the tightest radius we can use for a 2-8-0 locomotive scale: On30?  My curves have a 20-1/2" radius.
