The CBS story is mostly right, and it's cool that they reference chicagoswitching.com.
However the C&E South Line and the C&E North Line split at C&E Junction which is where the former Bloomingdale Line joined the C&E Line. The article was off on their locations. The Milwaukee Road used this terminology in describing the segments of the C&E. Today C&E Junction is in the middle of the vacated section of Kingsbury occupied by General Iron Industries, south of Cortland.
The article also does not point out that the reason for the Chicago & Evanston name of the line is that at one time it did indeed go all the way to Evanston! They imply it went as far north as Wrigley Field only.
