Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Someone pointed out in my youtube video of Kory Anderson's 150 HP Case that both the largest loco and largest traction engine have been revived only months apart 

Is this the largest steam loco? I don't know enough about them...

Not quite sure about that Nick, as there is some conflicting info regarding a couple of other engines. As I recall Norfolk & Western had a mighty big one, and so did one of the Iron Ore hauling lines up north in your neck of the woods. But I don't think the differences were much, and generally it is accepted that the Big Boy was number ONE. Many factors can be considered, such as total tonnage, or just weight on driving wheels, drawbar pull, cylinder bore size and operating pressure can all come into the equation.

Do you have any links to that huge traction engine?
