In larger systems, barns were generally indoor storage that allowed running minor maintenance that were subservient to a main repair shop. Some had dedicated painting, carpentry sections. Overhead cranes as far as I know, were not generally used as jacking seems to have been common to raise a frame. Machine shops, electrical departments usually shared shop space. I have never seen an overhead crane in a shop perhaps due to moving the cars in and out with overhead energized wire. Fabrication shops like the PE and IT and some others had who built or modified their own equipment may have used them.

The carhouse usually would not have overhead cranes because they interfere with the trolley wire.  The car house was for overnight storage of the cars and light maintenance.  On most systems there was also a separate shop. The shop may have had an overhead crane and the cars were either towed in or run in using portable cords. Many shops had short stub tracks so repaired cars would not be trapped behind cars under repair.  Many shops used car jacks.  Synchronized electric jacks are very popular today. Most cars are built with jack pads for use with jacks.

 

Thanks for the Yakima photos.  It has been many years since I have worked there. The two track building with the overhead crane was the shop. The carhouse was a low building next door. I do not know if the car house is still there.  The shop was certainly the more interesting building.  As I recall the capacity of the crane was fairly low, useful for removing traction motors from trucks, but the cars and locomotives would have to be jacked to get the trucks out.
