hinge joint not moving objects together

I am trying to make a garage door that rolls along the rails when a button is pressed. I know I am not the first person to attempt this, but I have not been able to find any videos/descriptions on how to do this in unity. My thought is to sculpt the rails, and add a wheel collider to each of the points where a caster would be on a real garage door. I'm thinking (as I am newer to Unity) that this will allow it to pull the doors in the right motion along that track when a force is exerted. Each section of the door has a hinge joint between them as well. I have a center hinge sculpted, and have a script that moves the hinge along the center rail when a button is pressed. This works very well, however it only moves that piece. I tried attaching it to the top of the door with various joints (I keep thinking hinge joint is the best) but the problem remains that when I play it, the garage door stays where it is, and simply detaches. Perhaps there is a simpler way to do all of this, and I am very open to suggestions, but I have been trying all day without any success. Ideally, I would be able to allow the player to press a button, and the garage door moves. Maybe I am using the wrong type of joint? maybe I'm not setting it up properly? As a side note, I also am attempting to do this without animations. The other doors I have in my scenes and projects all work very well without animation, and if possible, I want to continue that, as I was told by someone that animations are more processor intensive than using coding to transform/rotate/etc. Not to mention, there is much less setup involved from what I've experienced. Any and all help would be greatly appreciated.
