Is there anyway I could make this object run back and forth in a certain space? http://img480.imageshack.us/img480/1748/trainrr4.png
The object selected is the track I want the object on top of it to run on.
Forget the quality of this map, it is only a test map to see all that can be accomplished. I'm currently testing around with stuff.

you betcha. Check out the func_tracktrain entity (in combination with path_track).

Essentially you are just making an elevator that goes sideways. Check for tutorials on how to make elevators, like this one here:
