Mohave & Milltown Railroad (Arizona)

Hello Everyone. My name is Rick Bell and I am searching for any and all information on a narrow gauge railroad which once operated between Needles, AZ and Oatman, AZ. This line was approximately 17 miles long and only operated from 1903 to approx 1906. The line was called the Mohave & Milltown Railroad. It was constructed to carry ore from the town of Oatman and several surrounding mines, down to the Colorado River for further transport to a mill. I have located a short section of the old right-of-way and a couple of obscure pictures but that seems to be all. If anyone has ANY information on this line, especially any terminal track maps, I would be most thankful. I recently moved to Bullhead City, AZ., which is not far from the lines location.
I'm so glad the forum is back. I've read it for some time, but now that I'm retired, it's my first chance to tap all of your knowledge.

Best regards to all...
Sincerely,
Rick Bell
