According to this website a K4 on the Dyno at Altoona produced 3184HP for 60 minutes:

Here is an interesting nugget:

"at the most efficient steaming rate of 34,000 lb (15,422 kg)/hour, boiler efficiency was 76% and the engine burned fuel at the rate of 1.8 lb/ihp/hour (5,800 lb/hour)"

I haven't fired a locomotive but I have shoveled coal and 3 tons an hour for several hours is more than I can conceive of doing.

I wonder how many lives were greatly extended by the advent and use of the mechanical stoker....

My Dad got to watch a K4 on the Dyno. During that particular test they ran it at 60mph. Dad said it was pretty spectacular. BTW, regular Engine Crews were used for Dyno testing.
