I found this historic 1939 vintage photo from the Chicago, North Shore And Milwaukee Railroad at My Link page, "Dave's Electric Railroads", located to the right of Your computer screen.

A two car train from the Chicago, North Shore And Milwaukee Railroad, is viewed heading southbound through North suburban Northbrook Illinois. The train is traveling over the North Shore Line's own high speed Skokie Valley Mainline route.

I work in this area today, as a Paratransit Driver / Handicapped bus operator.
The North Shore's trackage was removed from the Skokie Valley Mainline, shortly after the Chicago, North Shore And Milwaukee went out of business in January of 1963.

Believe it or not...those high tension power line electrical towers are still standing here today in Northbrook, and most of the former North Shore Line, Skokie Valley Mainline right of way. The area today, is now home to high rise office buildings, the I-94 Edens Expressway, and a number of local retail strip malls.

The Skokie Valley Mainline alignment right of way itself, is now a dirt service road in many areas surounded by the high tension power line towers.
