How far are the tracks cut back from the mine site? I know the yard and the wye are gone, but the actual distance of removed track is something I'm not clear on.
As far as I'm aware, the tracks still reach the mine. I had an inquiry several years ago (when I was still a railroad consultant) from a party in the Albany area about the feasibility of using the tailings from the Tahawas mine as railroad ballast and road aggregate. The mine extracted titanium (ilmenite and rutile), not lead, so there is no contamination issue.
That idea never went anywhere at the time, but Google Earth will show you a VERY large tailings pile at the mine.
So it's possible we may see freight (and even passenger?) service north of North Creek. That would be fun, and maybe somebody will want to mine titanium again.
