In the UK, one of the train companies came up with cowling to streamline the engine. The result is aesthetically pleasing, but one of our engine designers, one Nigel Gresley went one stage further and produced an art deco streamlined engine, one of which, named Mallard, hold the world record of 126mph, to this day.

Mallard is of a design known as: "A4 Pacific." There is an A4 Pacific in the US. Number 4496 Dwight D. Eisenhower, originally the Golden Shuttle, subsequently named after the U.S. general in WWII. Donated to the U.S. by the U.K., the train is now on display in a railway museum outside of Madison, WI.

Is it that streamlining the locomotives isn’t all that aerodynamically effective until that babe hits a certain rate of speed?

I ask because the freight locomotives don’t appear to make anywhere near the nod to aerodynamics as those high-speed passenger train locomotives found in Europe and Asia.

You are 100% correct. Drag (and power required) goes up VERY non-linearly with speed.
However, even if you aren't going all that fast a good portion of the time, having that streamlined look makes it look fast, even sitting still.
