This site gives you info about the route: http://www.drgw.net/info/CaneCreekBranch But in short (If you don't want to read it from the site), Cane Creek is a single-track branch line in Utah. From the mainline at Brendel (a.k.a Crescent Junction), it's over 35 miles all the way to Potash. And only one local freight (The Potash Local) operates the line every Friday.
The scenery of the route looks pretty nice, I'm interested to see how exactly timetable mode will work if there is only one service a week. Maybe it will involve 1-2 extra trains each way and with some long timetable shunting scenarios at the Potash Mine.
Im still hoping Skyhook adds part of the UP mainline for this route from Thompson Springs to Green River, as well as the Uranium Tailing trains that run from Moab to Cresent Junction
