Much of the Espee line between Black Butte and Grass Lake was originally pieced together from various bits of logging railroads, and was quite the challenge operationally. John Signor's book Rails in the Shadow of Mount Shasta contains a map with the current mainline superimposed over the logging RR's. I recall the original junction was in Weed until the new line was built and the Jct. moved to Black Butte.
