Mike CT, thank you very much for the comprehensive 2 3 rail information and excellent photos. My engine is not a project any more. I hadn't planned on it being one of my main runners. It looks great and it's fun to have.
Since my Run Room theme is a Texas South Plains Railroad, that engine was imported by a Texas rancher oil man while he was on vacation in Europe. The rancher really liked the engineering model. He even hired the engineer and conductor to come home with the engine. Engineer and conductor speak no english. That steam engine will pull stock cars and oil tankers when needed and it will be running fast through the yard until some of the coating wears off the wheels.
