Hello,
        It works like an interactive remote control.  That way you can play with
it and develop your skill.  Vary few people have been able to walk the marble
uphill on the first try.  First RCX is for the base it has 2 motors and 3
rotation sensors.  1 rotation sensor has a knob and is mounted to a controller.
Second RCX is for the rail 1 motor and 2 rotation sensors.  1 rotation sensor
has a knob and is also mounted to the controller. The rail code basically
determines direction and speed by the difference and time apart of the 2
sensors. In other words the rail always trys to be in the same position as the
remote control.  The faster you turn the knob the faster the rail moves. The
base works the same way but is more complicated. I also have a preprogrammed
routine that can be accessed with the Lego Mindstorm brand remote.  Originally I
wanted To Have one RCX for both base and rail and a second to control it with
Infrared through lnp.  Unfortunately I never figured it all out.
HTH
Check back in a few days for a picture of the controller and I will also try to
get the code file moderated.
