Chicago & Illinois Midland Railroad

Last Revised: January 1, 2022

By: Adam Burns

The Chicago and Illinois Midland was, and remains, not particularly well-known as it operated a network of barely 100 miles.  

Its primary function was to provide transportation services for owner Commonwealth Edison, moving coal from the southern Illinois coal fields to power plants in Chicago.  

It all began as a very small operation established by local interests south of Springfield in moving agricultural goods to market.  

After coal became the primary focus the C&IM's purpose remained relatively unchanged for more than 80 years.  Its passenger business was, as one might imagine, relatively insignificant and these trains were abolished after World War II.  

Interestingly, the C&IM did not gain its name from the territory it served but rather the companies which owned it. Its patchwork network ran no further north than Peoria and no further south than Taylorville.  

In 1996 it became part of the Genesee & Wyoming family of short lines and its corporate name was changed as the Illinois & Midland Railroad. 

A Brief Corporate History

Because of its size there has not been many publications highlighting the corporate history of the Chicago and Illinois Midland.  In the mid-1950s the company released a short booklet on this subject entitled, "Chicago & Illinois Midland Railway Company: The Midland Story," that helps explain its heritage.  

The earliest component was the Pawnee Railroad, chartered in 1890 by local farmers in the rural community of Pawnee to ship their agricultural products to market much more efficiently than the traditional methods of wagons and horses.  

That same year the small pike opened a 4 mile system from the town to a connection with the Illinois Central at nearby Pawnee Junction, later renamed Cimic.  

In 1905 the Chicago Edison Company, which became Commonwealth Edison in 1907 (via merger with Commonwealth Electric) and headed by noted industrialist Samuel Insull, acquired the Pawnee Railroad in conjunction with Francis Peabody's Illinois Midland Coal Company.  

Their efforts were part of a larger plan to handle coal from seams situated in Sangamon and Christian Counties to power plants in Chicago.

Illinois & Midland, C&IM Successor

Genesee & Wyoming

On January 25, 1906 the system was reorganized as the Chicago & Illinois Midland Railway (Interestingly, its name did not derive from the city or region it intended to serve.  Instead, it was a combination of owners, Chicago Edison and Illinois Midland Coal.) then proceeded to expand both eastward and westward reaching Taylorville and Auburn.  

The former offered interchanges with the Wabash and Baltimore & Ohio while the latter provided connections with the Chicago & Alton (later Gulf, Mobile & Ohio), Illinois Traction (the future Illinois Terminal), and the Chicago & North Western at a location known as Compro (just west of Auburn).

The system remained regional in nature at less than 30 miles until March 17, 1926 when a segment of the moribund Chicago, Peoria & St. Louis Railroad was taken over.  

This system had struggled for years with a heritage tracing back to the early 1850's.  It had attempted to open a through route from Chicago to St. Louis and other points across the Midwest but constant financial problems derailed these hopes.

It was reorganized for a final time in early 1913 as the CP&StL and at that time maintained a 200 mile route from St. Louis to Peoria with short extensions to Jacksonville (via Havana) and Grafton (located north of St. Louis along the Mississippi River).  

Chicago & Illinois Midland Timetable (1969)

In 1924 the road was shut down and its assets liquidated.  The 84-mile section from Springfield to Pekin, then known as the Springfield, Havana & Peoria Railroad, was subsequently leased by the C&IM while the Illinois Central picked up the southern segment from Springfield into St. Louis.  

By acquiring its part the C&IM also gained a one-quarter ownership in the Peoria & Pekin Union Railway. This successful little terminal/switching carrier not only served numerous customers but also maintained a multitude of interchanges with major railroads including:

• Chicago & North Western


• Gulf, Mobile & Ohio


• Illinois Central


• New York Central


• New York, Chicago & St. Louis (Nickel Plate Road)


• Pennsylvania


• Santa Fe


• Burlington


• Rock Island


• Illinois Terminal


• Minneapolis & St. Louis 


• Toledo, Peoria & Western. 

The C&IM also worked out an agreement with Illinois Cnetral to utilize trackage rights between Cimic and Springfield (16 miles) which allowed it to operate both of its segments as a unified network.  The entire main line from Pekin to Taylorsville, via Cimic and Springfield, totaled 121 miles.  

The Modern Chicago & Illinois Midland

Coal, which comprised about 90% of the Chicago & Illinois Midland's annual tonnage, normally did move by rail all of the way into Chicago.  To reduce shipping costs a substantial rail-river coal transfer terminal was built in Havana along the Illinois River.  

From there the black diamonds were shipped north via barge.  According to J.P. Lamb, Jr.'s article, "C&IM Revisted" from the March, 1960 issue of Trains Magazine, most of the coal sent here derived from the Peabody Coal Company's Mine #10 near Ellis, Illinois while 60 to 80 daily loads interchanged from the Illinois Central and Gulf, Mobile & Ohio.

All of this went to either Chicago, home to eleven plants, or one generating station operated at nearby Pekin.  To move all of this tonnage the C&IM was laid with heavy 130-pound rail and relied on hefty 2-10-2's (either built new or acquired secondhand).  

Other wheel arrangements included 2-8-2's, 2-8-0's, various switchers, and a set of modern 4-4-0's for passenger service.  Not surprisingly, these trains were lightly patronized and scheduled #6 made its final runs in May of 1953.

Traditionally, all locomotive and car repair work was carried out at the primary shops in Taylorville.  However, this changed in the later 1950's when these facilities were moved to a more central location at Springfield which was also home to the road's headquarters.  

The C&IM contained a photogenic route, aglow in rolling hills and farmland, but not without its difficulties from an operational standpoint.  

Heavy coal drags heading towards the Havana terminal had to deal with a rugged 1.64% grade north of Petersburg referred to as either "Petersburg Hill" or just "The Hill."  

As the Trains Magazine article, "Oasis In Dieseldom" (August, 1955) notes, a lone 2-10-2 would pick up as much momentum as it could through Petersburg before tackling this stubborn grade.  

For a typical 60-car consist it had to repeat the assault two additional times utilizing roughly 20-car cuts.  During the mid-1950's the railroad began testing diesel road-switchers by leasing a few Milwaukee Road SD9's.  

Management liked their performance well enough to order a batch of five in 1955.  In addition, it picked up six SW1200's at the same time.  The original 11 diesels replaced a fleet of 26 steam locomotives.  There were also future orders for the rare RS1325, along with SD18's, and finally SD38-2's.

In the 1960's the bottom fell out on high-sulfur, bituminous coal due in part to the passage of the Clean Air Act.  The new law significantly hurt the railroad’s earnings and Commonwealth sought buyers for its railroad.  

Just around that time demand was growing for Powder River Basin’s clean burning coal and as a result Commonwealth retained ownership.  While it did relatively well for the next 20 years, interestingly it was deregulation that brought about its eventual sale.

Now that railroads could set their own freight rates C&IM’s parent found it was simply cheaper to contract with other nearby railroads rather than move the black diamonds through a subsidiary.  

So, in late 1987 the railroad was sold to private investors and then in 1996 was acquired by short line conglomerate Genesee & Wyoming.  Following G&W's takeover the company was renamed as Illinois & Midland Railroad.  

Today, the I&M remains a successful operation witnessing more than 100,000 annual carloads.  However, it no longer handles only coal with traffic consisting of "...agricultural/food products, building materials, wood products, minerals/ores, and municipal/ industrial waste."
