Water tower is one of the less noticeable features of the Okoba Station. It was once used for refilling the tenders of the hudge D51 locomotives that were often used in pairs in order to bring freight and passengers up the unbelievable 30 percent elevations around the station.
For years railfans have posted photos of its stone base, still intact today.
This photo was taken in August 1970. The other photos in the set show quite an amazing number of mixed passenger-freight consists, often headed by a pair of D51-s, somewhat contrary to a viewpoint that freight trains were not widely operated on the line after the easier coastal route was opened.
