The "Best" steam locos are the ones still operating that I get to see in person. Opinion!
I agree with Ace. I'm sure there were bigger, faster, "brute strength" steam locomotives in the past. But I think the best are the ones I can see, touch and photograph now. I have no expertise on any steam locomotives. I like them all. I've been lucky enough to ride numerous times on the Southern Pacific 2472, a P-8 Pacific. So I can identify with it. It's not the biggest, but it has operating steam now and personality. I also like the UP 844, which I've been lucky enough to see and photograph. To qualify: just my humble opinion. Matt
