 By the late 1970s, Southern Pacific (SP) was rarely using the westside line, now known as the St. Joseph Branch, from Saint Joseph north to Seghers, because traffic was mostly serving the Stimson Lumber Company sawmill and a few grain silos in and around Carlton.By 1980, SP was only storing cars on the line south of the junction to the sawmill, and by 1985, it had abandoned and torn up a long section of track from the mill junction to just north of Carlton.The tracks north out of Saint Joseph extended almost five miles and ended about a mile north of Carlton in order to serve the remaining Carlton customers.
