This is my first run on air after finishing the valve gear. The engine is described by Kozo Hiraoka in his book, "The Pennsylvania A3 Switcher (1st project for the beginner)". I've been working on the project off and on for about 5 years but only really started concentrating on it this year. This engine is 1.5" scale and runs on 7.5" gauge track. It currently weighs about 100lbs.
