The recent post concerning the Range of Light Film Festival in Yosemite led to me browsing the program and noticing one of the films concerned the Yosemite Valley Railway.
That prodded me into remembering a scan from many years ago ( 12 years already!? ) a friend had put on my web server.
for your enjoyment
Yosemite Valley Railway 1906 - 1945
It appears to be a reprint of two issues of "The Western Railroader" into one volume, both concerning the Yosemite Railroad.
