[4] Frederick E. Fisher (who had held the position of general manager for the Chicago and Joliet Electric Railway for six years, in addition to being the president of the JP&A and the general manager of the Fisher Construction Company) tended his resignation from the Chicago and Joliet Electric effective April 1, 1904, in order to focus on completing the JP&A.

[6] The Joliet, Aurora and Plainfield line was expected to be in operation by September 1904,[7] but the start of service was ultimately delayed until October 21, 1904.

[8] After being in operation for fewer than three full months, beginning Tuesday, January 17, 1905, the new interurban line began handling mail from Aurora to Joliet.

[9] By November 1905, officials from the JP&A were planning to operate an "automobile line" for the winter of 1905–06 between Yorkville, Plainfield, Sandwich, and Hinkley.

[11] Settlements from a collision in Joliet in which several passengers died crippled the finances of the line and the railroad had operated at a loss since 1914.
