Bruno, I will defer to Richard or Travis on this one, but here is what I THINK: I ,too, have noticed the phenomenon of which you speak. I think it is steam being forcefully ejected from the whistle bell that is ejected downward due to its having to make a "U-turn" in the bell. I know of no drain holes in the bowls of any steam whistles; in fact, a calliope must be "blown out", or cleared of condensate, before the whistles will speak properly. The downward-blowing steam we see seems to be more evident on some calliopes than others - I'm guessing this has to do with differences in pressures, volumes and whistle and supply line scales. I know Richard will straighten us out on this!
