The higher the axle, the higher all the rest of the loco sits above the ground. Recognizing that rails are kinda close together, you get a big machine that's tall and narrow and has lots of weight up on top.

Which means it's tippy. All else equal you'd rather have a wider lower-slung machine to go faster around corners. Part of the reason train tracks have such wide curves is just avoiding tip-overs.
