An earlier sunkink post reminded me of this picture. This is a sunkink on the former Western Pacific. The rail anchors here have a real challenge dealing the the expansion and contraction associated with temps in the 100's during the summer and well below freezing during the winter. I was riding the caboose on an eastbound SP train from Klamath Falls to Ogden, operating on the WP between Flanigan and Weso. The train made it over the kink without derailing, but the caboose took a mean jolt. I'm guessing the weight of the engines and heavily loaded lumber cars helped straigten out the kink, but when the light caboose hit it....wham and we big holed. Those riding in the caboose were thrown onto the floor, but fortunately nobody was injured (and my camera survived). The hat on my traveling companion was part of the uniform of aspiring supervisors in those ancient days on the railroad!
