Chicago
and Illinois Midland Railway - (en)
The Chicago and Illinois Midland Railway (AAR reporting marks CIM) was a
Class I railroad in the United States, serving Peoria, Springfield and
Taylorville, Illinois. It specialized in the hauling of coal. It was
purchased by Genesee and Wyoming in 1996 and renamed the Illinois and
Midland Railroad (AAR reporting marks IMRR).
The history of the Chicago & Illinois Midland Railway goes back to
1888 when the villagers of Pawnee, IL built a rail line from their town to
the Illinois Central Railroad mainline 15 miles south of Springfield, IL.
The railroad was named the Pawnee Railroad and was later extended eastward
to Taylorville, IL and a rail connection with what is today the Norfolk
Southern Railway.

In 1905, the Chicago Edison Company (the predecessor of Commonwealth
Edison Company, the Chicago electric utility) purchased the Pawnee
Railroad for the purpose of transporting coal out of the central Illinois
coal fields for Chicago Edison's coal-fired power plants in Chicago.
Samuel Insull, the founder of Commonwealth Edison helped develop the coal
fields along with Francis Peabody and his Illinois Midland Coal Company.
Thus the railroad's name was changed from the Pawnee Railroad to the
Chicago & Illinois Midland Railway Company, drawing its name not from
its terminal points (the C&IM never went to Chicago), but from its
corporate parents: Chicago Edison and Illinois Midland Coal Company.
In the 1920's, Insull bought some of the trackage of the bankrupt Chicago,
Peoria & St. Louis Railroad (CP&StL), running from Springfield,
Illinois to Havana, Illinois on the Illinois River and then running
northeast from Havana to East Peoria, IL. He connected his new acquisition
with the existing C&IM by obtaining 15 miles of trackage rights over
the Illinois Central from Springfield to the connection between the
C&IM and the IC at a point known as CIMIC. Insull then built a
rail-to-river coal transfer facility on the Illinois River at Havana, IL,
where coal could be dumped from rail cars into barges for shipment up the
Illinois River to Commonwealth Edison power plants located on the river in
the Chicago area. Insull, being a believer in "vertical integration",
thus was able to control the mining and shipment of coal, via his railroad,
to his coal transfer plant, to his barges, to his power plants, where it
was burned to create electricity for transmission on his lines to the
customers in Chicago.

When the Clean Air Act was passed in the 1960's, the market for high
sulfur central Illinois coal evaporated and the coal mines (at one time
numbering 15) along the C&IM closed one by one. Commonwealth Edison
put the C&IM on the market and offered to sell it for $1.00, but there
were no takers.
Then Commonwealth Edison changed its philosophy and began building power
plants in central Illinois, adjacent to C&IM tracks, sending
electricity to Chicago via high voltage lines. Soon the C&IM was back
in action, but this time it was hauling coal into central Illinois from
the Powder River Basin in Wyoming and Montana, instead of hauling coal out
of the central Illinois coal fields. Soon unit coal trains, received in
interchange from Burlington Northern and the Chicago & North Western
were traversing C&IM tracks to Commonwealth Edison's power plant at
Powerton (Pekin, Illinois) and to the still operating Havana Coal Transfer
Plant.
However, by the late 1980's Commonwealth Edison's philosophy changed again.
In the wake of railroad de-regulation in 1980, they began seeking
competitive bids from railroads who could deliver western coal directly to
Chicago. As a result, Commonwealth Edison sold the C&IM in December
1987 to a group of private investors. The ownership of the C&IM
changed hands twice more before it was purchased by Genessee & Wyoming
Industries in 1996 and the name was changed to Illinois & Midland.
