Chicago and Alton Railroad system as of 1918, including the Toledo, St. Louis and Western Railroad (Clover Leaf) in orange, parent of the Alton until 1921
The earliest ancestor to the Alton Railroad was the Alton and Sangamon Railroad, chartered February 27, 1847, in Illinois to connect the Mississippi River town of Alton to the state capital at Springfield in Sangamon County.[3] The line was finished in 1852 with the first locomotive trip from Alton to Springfield on September 9, 1852.[3] The Chicago and Mississippi Railroad extended to Bloomington in 1854 and Joliet in 1855. Initially trains ran over the completed Chicago and Rock Island Railroad to Chicago.
The Joliet and Chicago Railroad was chartered February 15, 1855, and opened in 1856, continuing north and northeast from Joliet to downtown Chicago. It was leased by the Chicago and Mississippi, providing a continuous railroad from Alton to Chicago. In 1857 the C&M was reorganized as the St. Louis, Alton and Chicago Railroad, and another reorganization on October 10, 1862, produced the Chicago and Alton Railroad. The C&A chartered the Alton and St. Louis Railroad to extend the line to East St. Louis, opened in 1864, giving it a line from Chicago to East St. Louis.[4]
The city of Bloomington, Illinois was the headquarters and primary repair site beginning in the 1850s. The repair shops for locomotives and rolling stock were located on the west side of the city between Seminary and Chestnut Streets. These were made of wood and burned in 1867. In 1883 the shops were substantially rebuilt on 40 acres of new land with 15 stone buildings. At that time the shops concentrated mainly on car repairs, but in 1905 they were expanded to accommodate major repairs and rebuilding of locomotives. At the peak of operations in the 1920s the shops employed 2,000 people.[5]
In 1925 Chicago and Alton carried 2,143 million revenue ton-miles of freight and 202 million revenue passenger-miles on (at year-end) 1,056 miles of road and 1,863 miles of track. Same numbers for 1944 were 2596, 483, 959 and 1717. By 1950, all of the Alton's steam locomotives were replaced by diesel locomotives.[6]
The first sleeping car designed by George Pullman was built in the C&A's Bloomington shops and introduced on September 1, 1859, on the Chicago-St. Louis route. Sleeping cars were operated over most routes between Chicago, Peoria, Bloomington, St. Louis and Kansas City in principal train consists. Successor Gulf, Mobile & Ohio operated Chicago-St. Louis sleeping car service until December 31, 1969, the last railroad to do so between the two cities.
The first dining car, the Delmonico, named for the famous New York restaurant, was built by Pullman in the Aurora, Illinois, shops of the Chicago, Burlington & Quincy. The car first appeared in regular service over the C&A's Chicago-St. Louis mainline. Two other Pullman diners built at the same time, the Tremont, and the Southern, were leased, providing dining car service on all three principal C&A Chicago-St. Louis trains. Dining cars were a part of Chicago-St. Louis train consists until May 1, 1971, with the takeover of passenger service by Amtrak.
In 1932 the Alton was the first Chicago-St. Louis Railroad to install air conditioning on its passenger trains.[7]
First entry of C&A passenger trains from Joliet into Chicago was over the Chicago & Rock Island to that railroad's depot (later La Salle Street Station). Briefly, passenger trains were moved over to the Illinois Central depot. On December 28, 1863, the leased J&C and Pittsburgh, Fort Wayne and Chicago Railway came to an agreement where the J&C would use the PFW&C's terminal at Madison Street, later becoming a tenant of Union Station, which opened in 1881. In 1924, with the completion of a new Union Station between Adams and Jackson streets, C&A became a tenant and its successors used Union Station until the takeover by Amtrak.

Railroads in italics meet the revenue specifications for Class I status, but are not technically Class I railroads due to being passenger-only railroads with no freight component.
