thank you the stell alloy came with the train.

I just got the Santa Fe Flyer.  I set it up as they told me in the book.  Put the train and i get  humming and it will not move.  I also have the steel alloy and the nickel silver rails.  Can i mix them together.   
   
I look at my controller it has a plug for the track and one for the power to go in.  Two differant type of plugs.
