Looks like the 'rails' have a slot in the underside which should (like the long ago original Sky-lines) have a moving chain in it that the boxcars hooked into to move them (the original skyhook looked like a hook then also). Of course you couldnt change speed or direction like they have you able to do in the final game mechanics, but you did actually go somewhere on those original skylines instead of in circles like the delivered game.
