Live steam? This will be a very interesting project to watch, especially in such a large locomotive size. Will these engines be European looking?Oh, I was born and live in the USA, I'm of Polish heritage, so you're not far off with my name. I currently have a Revell Big boy model for HO but I couldn't complete it as parts were missing or broken. I'm mostly using it for physical measurements, then converting them from HO to Live Steam (1:8, gauges 0'7.5" and 0'7.25") I'm also using plans from other engines for cylinder thickness for when I get equipement to actually prototype and test parts, then I can actually make the locomotive I'm designing. which is a single expansion-double compound mallet with a wheel configuration 4-6-8-4 and 2-6-8-4.
