General Overview:
The Mount Carmel (or Cook County) Branch was the small, single track branch of the Aurora & Elgin built to serve the Oak Ridge and Mt. Carmel Cemeteries located in the village of Hillside. It left the Main Line at Bellwood where it headed south before eventually turning and running west in the vicinity of Roosevelt Road.
Construction of the branch was done under the Cook County & Southern Railway (a subsidiary company of the Aurora & Elgin which was created solely for this purpose). Unlike the rest of the railroad which used third rail as the primary source of power to the trains (hence the nickname the Great Third Rail) the Mt. Carmel (Cook County) Branch was built without a single section of third rail. Instead the entire branch was operated under overhead trolley wire. While this was typical for most interurbans, it was quite the aberration for the Great Third Rail.
Service began on March 18, 1906. A single car shuttle provided service between Mt. Carmel Cemetery and the stub-end track at Bellwood.
Non-funeral passenger service came to an end on October 31, 1926, due to the opening of the nearby Westchester service which also branched off of the Main Line at Bellwood Avenue. Bus service was inaugurated as a connection service between Oak Ridge and Mt. Carmel Cemeteries to the Roosevelt rapid transit station on the Westchester branch.
But even though passenger service ended, the branch continued to remain of no small importance to the Aurora & Elgin as it became a major source of the railroad's carload freight.
So important was the freight supplied by the branch that after the Aurora & Elgin shut down completely, the Mt. Carmel (Cook County) Branch lived on. It was purchased by the Indiana Harbor Belt who continued to use the line all the way until 1986 (twenty five years after complete abandonment of the CA&E) when it was finally abandoned.
