I like the small sheds and booths seen along the rails. I made this one for a friend. It's a model of a electrical crossing shed seen at crossings in the Midwest.
it has a front light opening for an LED to show that the electronics is working. note the top installation lifting hooks are bent inward as they would be after installation. The doors are separate so you can add the graphics before attaching to the shed.
If you want to make them, I'll send you the .stl files.
