The Rock Island District (RI) is a Metra commuter rail line from Chicago, Illinois, southwest to Joliet. Metra does not refer to its lines by color, but the timetable accents for the Rock Island District line are "Rocket Red" in honor of the Chicago, Rock Island and Pacific Railroad's Rocket passenger trains.
History
The Suburban Line was built in 1870 as a steam dummy line, splitting from the main line just north of 99th Street, running west along 99th and turning south to the present line at the S-curve just south of 99th. The crossing of the Pittsburgh, Cincinnati, Chicago and St. Louis Railway midway along 99th was known as Dummy Crossing. In the early 1890s the line was extended north to 89th Street in conjunction with the expansion of the Chicago Terminal Transfer Railroad, and the portion on 99th was removed.
The track is owned by Metra, bought from the bankrupt Chicago, Rock Island and Pacific Railroad for $35 million in December 1982 (equivalent to $ in ). The Regional Transportation Authority had signed a contract with the Rock Island in 1976 to fund service, and in 1980 the Chicago and North Western Railway began operating the Rock Island District (the Rock Island also ceased operations that year.) In spring 1981 the C&NW stepped away, and the Northeast Illinois Regional Commuter Railroad Corporation (Metra) was formed to take over operations. Through freight trains on the line are operated by CSX and Iowa Interstate Railroad on a trackage rights agreement. In addition, Chicago Rail Link has rights to operate local freight service on the whole district, and it also uses the line between Gresham Wye and Blue Island to connect with the Iowa Interstate and Indiana Harbor Belt Railroads.
A new station at 35th Street and Federal Street opened on April 3, 2011 to serve U.S. Cellular Field and the Illinois Institute of Technology. It was named 35th Street/'Lou' Jones/Bronzeville Station after Lovana Jones who was an Illinois State Representative in the Bronzeville neighborhood.
The Englewood Flyover, an overpass located in the Chicago neighborhood of Englewood, eliminated delays for the Rock Island. The overpass replaced a diamond crossing with the Norfolk Southern's Chicago Line. The overpass proposed by Chicago Region Environmental and Transportation Efficiency Program (CREATE), which cost $142 million to construct, was completed in October 2014.
In recent years, Metra has expressed a desire to electrify and modernize the line if funding became available. In October of 2023, Metra announced the order of 16 lightweight electric multiple unit trainsets that would likely be used on the Beverly Branch. They could be used to increase frequency and speed.
Service
As of September 7, 2021, Metra operates 80 trains (40 inbound and 40 outbound) on the Rock Island District on weekdays, with 21 trains providing roundtrip service to and from , three to and from , and 16 to and from . Between and Blue Island, all trains terminating at Blue Island as well as four evening through-trains to and from Joliet operate via the suburban branch, while all other trains remain on the mainline.
On Saturdays, Metra operates 33 trains (16 inbound and 17 outbound) on the line, with 10 roundtrips to and from Joliet, six roundtrips to and from Blue Island, and an additional outbound train to Joliet. The Blue Island short-turn trains, as well as four inbound and five outbound through-trains to and from Joliet operate over the suburban branch, while the other six Joliet through-trains in each direction remain on the mainline.
On Sundays, Metra operates 28 trains (14 roundtrips), eight to and from Joliet, and six to and from Blue Island. All six Blue Island short-turn trains as well as two through-trains to and from Joliet operate over the suburban branch, while the other six Joliet through-trains in each direction remain on the mainline.
The Rock Island District consists of the former Rock Island main line to Joliet and the slightly longer suburban branch that loops to the west between Gresham and Blue Island. Most trains use the latter; the two stations on that part of the main line are served only during weekday rush hours.
