CNWman, What RR and what type of steamer? Should be fun for you. I'm old enough to remember seeing them on the PRR & Reading main lines & I still get a kick out of seeing and riding behind them.
According to the info I have, it's on the Whitewater Valley RR and Flagg Coal Company # 75, a saddle tank 0-4-0.
Here's the steamer's own netpage:
