If an electric train is traveling north at 50 mph and the wind is blowing south at 50 mph, which way is the smoke blowing?

The last few electric trains I saw didn't have any smoke.  However, if they did, the smoke after a few seconds would be traveling with the wind; south at 50 mph.

p.s.  Nice gotcha, Dora
