Hi Cube
You've probably already figured this out... Now - I might be wrong... seems like the current collector is for an older version of this mod, but is most likely kept in for backward compatibility (ie. people updating their factories to the new version of the mod would lose their current collectors if the dev removed it.)
I'm not sure, but I have tested this is in creative mode and just having a powered control station is enough, and you only need one it seems. Make sure you are using the e-locomotive, as you may still be using the fuel-based locomotive - hence it not driving for you :)
Good luck :)
