One of it's names anyway. It is now doing business as the 'Clark County Community RR'. It was originally started as the 'Vancouver and Yakima', a route to the East from Vancouver, WA to Yakima, WA and a connection to the UP East through the Cascade mountains. Once the line got to timber country, and the sawmill at Chelatchie Prairie, WA it started making a lot of money hauling finished lumber to Portland, OR during it's growth phase in the early 1900s and further development was tabled. Now, the sawmill is scrap, and it runs excursion trains and delivers bulk freight to local businesses along the route.
41 miles from the UP/BNSF connection to the old mill site.

Real crossing at the Lewis river

Virtual recreation

The grade from the UP/BNSF connection to the Minnehaha yard hits 2.5% a couple of times, but the rest of the run is 2.0% or less.
This one is going to be easy for me to research, as I can drive the length of the line in ~2 hours.
Track is laid, now leveling and putting in grade crossings. Will not be finished until the tree decals are here.
