Friends Train Passenger "Power Function"

My son has since one moment a goods train Lego with which he plays much. But my daughter who is fan of Lego Friends is sad not to have a train dedicated to the girls and she asked to me whether it were possible of him to manufacture some to supplement its Friends universe.

Here how was born my idea.

It is about a train of radiocontrolled passenger, with the bright colors, specific to the universe Lego Friends. I unfortunately could not build it in reality because I do not have all the parts.

Even if my project does not succeed, I think that the idea deserves reflection because the girls who like to play Lego would be certainly glad to catch their train with them.
