Kelso Depot
Kelso Depot, established in 1905 and situated in the middle of the Mojave Desert. It seems like a unusual location, but was crucial in reaching the West Coast. West of Kelso was a steep grade that trains would need to climb with the assistance of "helper engines". There was also a natural spring that provided a water source for the steam locomotives. Kelso Depot was critical in supplying both of those resources.
