Both Canada and Mexico use the International System of Units (SI) measurement (aka. "metric") system in general.. Canada however still uses what is now known as U.S. "customary units" for railroad purposes, which I'm sure is due to the huge U.S. interchange. Is Mexico also still using U.S. "customary units?
