Yes, the Skokie Subdivision was the official designation by the C&NW and the UP for the line that extended south from Valley Junction. It more or less paralleled the Edens Expressway. It also followed ran in the Skokie River watershed or valley, such as it is, which is where the \"Valley\" designation came from. There\'s still a wooden trestle over the Skokie River in the Northbrook area that these trains ran across.
After the North Shore Line interurban abandoned operations in 1963 the C&NW moved their freight trains from their own line that ran alongside the North Shore Line just to the west onto one of the two main NSL tracks, abandoning their own line. Word was that the NSL tracks were in better shape. The C&NW cut over to the NSL tracks just north of Dempster St. where a lazy curve connected them after the NSL abandonment. The NSL line south of Dempster became the CTA\'s Skokie Swift/Yellow Line.
