I will say that while the locomotive art on the fuel oil tank is accurate in appearance, it should be on the tank closest to and facing the water tower.
The side where it is located in the simulator should have the large "Historic Route 66" shield and welcome message:

What a Country!: Kingman, Arizona Route 66
Beautiful renderings nevertheless, my admiration and respect for including what they have rather than blank generic stuff!
(Sometime several years ago I shot several photos of the tanks, hoping to create a photo-realistic paper model of them. We... don't talk about my lack of progress in that endeavor!
