Chad, I have a copy of that Pentrex video on VHS. It covers all of California Northern's operations. It's a great video! It includes everything from unit trains of Napa pipe to sugar beets to lumber. There are also three segments in which the Pentrex crews ride in the locomotives, including through Cloverdale Canyon and southbound from Willits (in one of the SD9's!). 100 minutes long, released in 1995.
