They've filled up the line with stored rolling stock again, have they? In past years, this stretch of track has been used to store grain hoppers and mixed freight cars, as well as other groups of intermodal cars. They've also tried storing intermodal cars on the stretch of line between Centralia and Chehalis (also visible from I-5). I've come to think of it as one of the longest single-track rail yards in the U.S.
