A 1.5 mile (corrected) long "wharf" or "Plankwalk" train? Is this correct?

It looks like it is 1.5 miles, not 15. 

1.5 is what it looks like to me, although Eureka has the logging history, with a loggers' style  pancake house in operation, when l was there.  I missed this monument, and probably much more,  and this is first l have heard of this railway.  I THINK E Clampus Vitus was formed as a gold rush miners' protective organization that may have been active in "lawlessness" enforcement and punishment. (Don't remember details so correct me if wrong.  Has been written about in gold rush/mining history/Columbia, Cal./ Hwy. 49)

Thanks for the correction, I wondered where that would have gone? I also went to the Samoa cook house, neat place (last remaining cook house in the west) and there is a train group and round house down the hill behind it.

(Just found the group with the trains: The Timber Heritage Association)

I don't know anything about this railroad.  I do know that wharfs were built along the CA coast to transfer logs and lumber from the then abundant redwood forests to logging ships that anchored off the coast.  The ships took the lumber to San Franciso where it was used to build the city and other Bay Area communities such as Oakland.  This was a huge and lucrative business.  NH Joe
