S P and the Bull Dog RR
I am sending along a picture of a shovel-head that is marked thus; 8 35 BULL DOG RR S P LINES. I am familiar with August, 1935, I have seen the railbed of the Bull Frog RR near Rhyolite, Calif., and the SP Lines is not a stranger here. BUT, I have NEVER heard of the BULL DOG Railroad, and why would the Bull Dog RR be associated with the SP?
I would guess the BULL DOG RR refers to the type or maker of the shovel, does anyone else have a theory?
