Bob,
  Thanks for posting this picture of Klamath yard.  I don't think anyone would consider the
caption "the main line up and down the West coast" as being particularly descriptive.  I'm
sure that is how the photo is captioned ... just saying that going thru Klamath was an
alternative to the Siskiyou line.  Still a nice picture and thanks.
