You can occasionally see cars of rocket casings and the like, on there way to the middle of nowhere, where they do that testing, on your way from Ogden up to Promontory Point, on the branch that is there from days the "old" CP.

At first I saw these huge tubes on flats and thought they were some kind of wind turbine assembly, but they looked light, and the wrong size, then I remembered we were only ten miles from Morton Thiakols rocket test facility, and I realized these were casings for solid fuel rocket boosters.
