Despite what Seinfeld may think, this is not an "amazing idea." The power generated by a windmill comes from the air pushing against the blades. The locomotive would also have to push against the windmill with an equal force in the opposite direction. Therefore, even if you assume 100% efficiency, the windmill can only produce enough power to push itself forward with nothing left for the locomotive. If you have anything less than 100% efficiency (as any machine would have), you are actually spending more energy pushing the windmill through the air than you are getting in return. Also, how would this theoretical locomotive accelerate from a stop with no air moving over the blades?

Power required for electric loco is huge.... even if you build one wind mill and fix it on loco -it will not be able to support the load requirements....
Also, it will add to drag and weight of loco - thus it is not a vaible option as of now....
One more factor - wind velocity requirements for a wind mill to function effciently are very specfic and cannot be found every where...
.....

The wind turbine would have to be so huge, you won't get the train through tunnels....!

Well I know America wont come up with this because we waste our money blowing innocent people up.
But that is an amazing idea.

No such thing as perpetual motion
