The Chicago South Shore and South Bend Railroad, also known as the South Shore Line, is a Class III freight railroad operating between Chicago, Illinois, and South Bend, Indiana. The railroad serves as a link between Class I railroads and local industries in northeast Illinois and northwest Indiana. It built the South Shore Line electric interurban and operated it until 1990, when the South Shore transferred its passenger operations to the Northern Indiana Commuter Transportation District. The freight railroad is owned by the Anacostia Rail Holdings Company.
The Elgin, Joliet and Eastern Railway was a Class II railroad, making a roughly circular path between Waukegan, Illinois and Gary, Indiana. The railroad served as a link between Class I railroads traveling to and from Chicago, although it operated almost entirely within the city's suburbs, only entering Chicago where it served the U.S. Steel South Works on the shores of Lake Michigan. Nicknames for the railroad included "The J" and "The Chicago Outer Belt Line". At the end of 1970, the EJ&E operated 164 miles of track and carried 848 million ton-miles of revenue freight in that year alone.
The Niles Car and Manufacturing Company was an American manufacturer of railroad equipment, including many streetcar and interurban cars. It was founded in 1901 in Niles, Ohio and published catalogs showcasing their various cars.
The Chicago North Shore and Milwaukee Railroad, also known as the North Shore Line, was an interurban railroad that operated passenger and freight service over an 88.9-mile (143.1 km) route between the Chicago Loop and downtown Milwaukee, as well as an 8.6-mile (13.8 km) branch line between the villages of Lake Bluff and Mundelein, Illinois. The North Shore Line also provided streetcar, city bus and motor coach services along its interurban route.
The Chicago Aurora and Elgin Railroad (CA&E), known colloquially as the "Roarin' Elgin" or the "Great Third Rail", was an interurban railroad that operated passenger and freight service on its line between Chicago and Aurora, Batavia, Geneva, St. Charles, and Elgin, Illinois. The railroad also operated a small branch to Mt. Carmel Cemetery in Hillside and owned a branch line to Westchester.
The Illinois Terminal Railroad Company, known as the Illinois Traction System until 1937, was a heavy duty interurban electric railroad with extensive passenger and freight business in central and southern Illinois from 1896 to 1956. When Depression era Illinois Traction was in financial distress and had to reorganize, the Illinois Terminal name was adopted to reflect the line's primary money making role as a freight interchange link to major steam railroads at its terminal ends, Peoria, Danville, and St. Louis. Interurban passenger service slowly was reduced, ending in 1956. Freight operation continued but was hobbled by tight street running in some towns requiring very sharp radius turns. In 1956, ITC was absorbed by a consortium of connecting railroads.
The Elgin and Belvidere Electric Company was a 36-mile (58 km) interurban line that connected Belvidere, Illinois and Elgin, Illinois. It was the central link in the interurban network connecting Freeport, Rockford, Elgin, and Chicago which included the Rockford and Interurban Railway to the west and the Chicago, Aurora and Elgin Railroad to the east. The line was operational from 1907 until 1930. In 1927, the line was extended to Rockford over a line of the Rockford and Interurban.
The Jewett Car Company was an early 20th-century American industrial company that manufactured streetcars and interurban cars.
The Aurora, Elgin & Fox River Electric (AE&FRE), was an interurban railroad that operated freight and passenger service on its line paralleling the Fox River. It served the communities of Carpentersville, Dundee, Elgin, South Elgin, St. Charles, Geneva, Batavia, North Aurora, Aurora, Montgomery, and Yorkville in Illinois. It also operated local streetcar lines in both Aurora and Elgin.
The Jake Award is an annual award presented to North American short line railroads by rail transport industry group American Short Line and Regional Railroad Association. The award recognizes railroads with a frequency-severity index (FSI) rating of 0.00, thus having no FRA reportable injuries.
The Chicago, Peoria and St. Louis Railroad (CP&StL) was a railroad in the U.S. state of Illinois that operated a main line between Pekin and Madison via Springfield. Its property was sold at foreclosure to several new companies in the 1920s; the portion north of Springfield has since become the Illinois and Midland Railroad, while the remainder has been abandoned, except for a portion near St. Louis that is now owned by the Norfolk Southern Railway.
The following is a brief history of the North American rail system, mainly through major changes to Class I railroads, the largest class by operating revenue.
The Chicago, Aurora and DeKalb Railroad was a 29-mile (47 km) interurban line which operated from 1906 to 1923 and connected the cities of Aurora and DeKalb, Illinois. The line made connections in Aurora with the Aurora, Elgin and Fox River Electric Company, the Chicago, Aurora and Elgin Railroad, and the Aurora, Plainfield and Joliet Railroad. Entry into Aurora was made via streetcar trackage of the Aurora, Elgin and Fox River Electric. Over the course of its history, the railroad used internal combustion, steam, and finally electric traction as motive power.
The Aurora, Plainfield and Joliet was a 22-mile (35 km) interurban railroad which operated between its namesake cities of Aurora, Illinois, Plainfield and Joliet in northern Illinois from October 21, 1904 to 1924.
