Mikado type (2-8-2) locomotive #765 was built by Baldwin for the Elgin, Joliet & Eastern Railway in 1929.
The Joliet, Aurora & Northern was incorporated in 1884 to build from the Indiana state line west through Joliet and Aurora to the Mississippi River opposite Dubuque, IA, but by 1886, the company had only got as far as Aurora. In 1887, two separate companies, the Elgin, Joliet & Eastern of Illinois and the Elgin, Joliet & Eastern of Indiana, were incorporated to construct a line from Valparaiso, IN, west through Joliet, IL, and then north to connect with the Milwaukee Road near Elgin, IL. The EJ&E of Illinois took over the Joliet, Aurora & Northern in 1888 and the following year merged with the EJ&E of Indiana.
In 1898, the EJ&E and the Chicago, Lake Shore & Eastern came under the control of the newly created Federal Steel Company headed by Judge Elbert Gary, after whom the city of Gary was named. The EJ&E then expanded by purchasing several smaller lines, including the Waukegan & Southwestern Railway, the Gardner, Coal City & Northern, the Western Indiana and, eventually, the Chicago, Lake Shore & Eastern.
