I've mentioned a few times that I wanted the freight doors on the depot to be movable, so that I could open or close them at will. I've thought long and hard about how to do that. After a couple of failed efforts, I found the answer, and it works REALLY well!
Starting with Plastruct "U" channel, item #90582, I cut a piece 24 scale feet in length, long enough to allow the door to be opened all the way with room to spare. To this "U" channel, I glued a piece of #90713 strip, also 24 feet in length. This gave me a nearly enclosed rectangular channel with a small gap along one edge.
Using Plastruct's "Z" channel, item #90592, I made hangers, gluing them to the top edge of the door using CA. These z-shaped hangers fit right into the gap in the rectangular channel that I built.
The result is a convincing hanging door. The track is slightly larger than scale, but it works for me, and gives me the sliding door that I wanted.
After painting and weathering, I now have one nice-looking hanging freight door.

After a light dosing of graphite, the door slides freely along the track, allowing me to open or close the door as I see fit. Exactly what I wanted!
