BNSF Seattle Sub Trains Pt. 3: Napavine Hill Region (Vader, Winlock, and Napavine)

Continuing north up BNSF's Seattle Sub, we start at the Cowlitz River Bridge and work our way uphill (for northbounds) through Vader and Winlock up to the top of the grade at Napavine. We then view a handful of trains on the north slope of the hill. BNSF, UP, and Amtrak are all well-represented.
