This was a engine that we found at the B & O Railroad Museum. We were fortunate to catch it while it was open. There were three engines in this building. This was the largest of the three. Here my Dad, M, Adrian and Carol stood in front of it to give a scale of how large the thing is. The water car held 25,000 gallons which is more than what is in our swimming pool. The largest wheel on this thing was just about 5 1/2 feet. When I first saw it, it took me a second to take in how massive it is.
