On December 1, 1909 the railroad added a branch from near Wheaton to Geneva. This was extended to St Charles August 25, 1910 Most of the interurban's lines used a third rail for power collection, which was relatively unusual for interurban railroads. While third rail had become the standard for urban elevated railroad and subway systems, most interurban railroads used trolley poles to pick up power from overhead wire; the AE&C only used trolley wire where necessary, such as in the few locations where the interurban had street running.
