Thanks for the information on the Mammoth operations.
After digging a little deeper I have discovered that the picture in
question (showing a 24"-30"? electric RR) was mislabeled. I think
that it might be the electric RR located at the Gladstone mine. This
would make it a gold mining operation. I knew the Mammoth electric
was 36" but I thought maybe there was a second smaller operation at
the same site. The picture threw me off.
I was also incorrect with regards to the 36" steam at the Kennett
smelter. I was thinking of the Keswick smelter to SP line duel gauge
of the Mountain Copper Company. That's what I get for not checking my
notes. The switching at the Kennett smelter was handled by the SP
Where did you come across the information that you found? I'm
interested in any further documentation of these railroads.
Thanks for setting my facts straight.
