The H K Porter catalog reprint has a formula for estimating steam locomotive horsepower (and other formulas too). Plugging in the data for a K-27 gives a horsepower of 450 and a hauling capacity on a 4% grade of 183 tons. There are couple variables which had to be estimated which will account for a variance in actual tonnage on a 4% grade.
What tonnage are K-27's rated at on a 4% grade?
