How far above the railhead would you say is the center of gravity for your average empty STMFC?




Our software team has added curve resistance to the rolling resistance values and while doing so tossed in something else for tipping over at some relationship of curve radius, super-elevation, and speed. I think it’s far too sensitive but I need a  decent center of gravity estimate to make the case.

I've never seen a discussion of this in the traditional trade literature, likely because it only affected passenger trains, and then, the locomotive, being an iron tank filled with water mounted above a rather tall running gear, would have been affected before the train, so your best bet would be to search period literature for the effects of CoG on locomotives.
