I haven't done a train one for a while, one of my favorite subjects. This one is actually not a full size train, it's the 15 inch Wagner that I get to help operate in Rollag, MN. I was in the process of "Blowing it down". You wait till the pressure has dropped pretty low and then you open a valve to let the remaining water and steam blow out any crud that may have gotten into the boiler and then allow it to dry out. This was in preparation for winter but it's something you would do if you aren't going to run for any length of time as well to fight deterioration of the boiler from rust. I liked the way the light was hitting the steam and the angle made the engine appear as if it's larger than it is.
