needed reduced axle loadings because a) it was built relatively late as
compared to other railroads, and thus was built to more modern standards and
b) was mostly mainline with almost no small branchlines. WP could easily
accommodate very heavy engines.

I believe the distinction between light and heavy was one of axle loading.
Both used the same running gear, but many railroads had lighter rail that
necessitated the use of a smaller boiler to reduce the overall per-axle
load. At the moment I forget what the axle loadings were.
