The Pacific Coast Borax Company ran mine tours as a tourist attraction in Death Valley before WWII. Today the little locomotive is on display at Furnace Creek Ranch, Death Valley National Monument. It is a gas-mechanical of 24 inch gauge; weighs about three tons. Built by Plymouth Locomotive Works as their c/n 77 in 1916.
I am not talking about the far larger Death Valley Railroad locomotive built to 36" gauge; and displayed at the same site.
I would love to see a modern picture or a link to one. I do have a real photo post card of it back before WWII.
