A train can easily run in a head- or tailwind in the same order of magnitude as its groundspeed.

I've been tempted to mount a small anemometer to my car - by subtracting the groundspeed from the measured airspeed, one can get the wind speed and direction and figure out whether there is a headwind or tailwind and if so how strong. Theoretically this could be used to drive more efficiently, though the extra drag from the anemometer would probably cancel out any gains.
