It didn't last long but there was the Seattle North Coast Railroad. It ran on former Milwaukee Road track between Port Townsend and Port Angles Washington. It was connected by a car float operation between Seattle ans Port Townsend.
My all time favorite Pacific NW short line. Some nice memories of this, especially as it ran in a very favorite area, the Olympic Peninsula.
It just so happens this is also my favorite NW Fallen Flag shortline!! So much I have two F-units being custom painted!!
