    Makes you wonder whether any practical use was ever made of these classifications. I'm sure that most shedmasters would know which types were best suited for each assignment without reference to the power class.

    Here's an interesting snippet from Wikipedia: "The Midland Railway introduced a system of locomotive classification based on the power output represented by a locomotive's tractive effort at 50 mph (passenger locomotives) or 25 mph (goods...

    I don't have any data to back this up, but I would have thought that an Ivatt 2MT 2-6-2T, with full tanks, must have a higher axle loading than its 2MT 2-6-0 tender equivalent. But maybe they did something clever with weight distribution ....
