This town is on the original IC charter line between Freeport and East Dubuque. Because the Chicago, Madison & Northern route was built by IC to connect Freeport to Chicago, this CN/IC route to the West still exists. The Milwaukee route is abandoned.

| Dave Martens posted Here's a Sanborn map from 1898 showing the shared Milwaukee Road and Illinois Central facilities at Warren, IL. The Mineral Point RR built from Warren, IL to Mineral Point, WI by 1856. Warren was the MPRR's only connection to the outside world at that time. The Milwaukee Road purchased the MPRR in 1880 and the MILW then built west from Monroe, WI to Gratiot and Shullsburg. The MILW connection from Monroe to Gratiot rendered the Gratiot-to-Warren connection redundant because the MILW did not want to give traffic to the IC at Warren instead of the MILW keeping the traffic for itself through to Milwaukee or Chicago. The MILW abandoned the Gratiot-to-Warren line around 1923. Part of highway 78, south out of Gratiot, is on the former MILW Gratiot-to-Warren roadbed. The turntable seen in this map was for turning MPRR/MILW locomotives. The depot at Warren was an IC design but was used by both railroads. Recent research uncovered that the MILW paid the IC about $300/year for use of the IC's facilities in Warren. |
