The IAIS and the railroad infrastructure were purchased from Heartland by Railroad Development Company of Pittsburgh, Pennsylvania, in 2003.
In recognition of the railroad's Rock Island Railroad heritage, the IAIS logo uses a shape similar to the original railroad's logo and has also painted two of its General Electric ES44AC locomotives (513 and 516) in Rock Island inspired paint schemes.
Council Bluffs Subdivision (Council Bluffs to Des Moines, Iowa)
Newton Subdivision (East Des Moines to South Amana, Iowa)
Iowa City Subdivision (South Amana to Silvis, Illinois)
Blue Island Subdivision (Silvis to Bureau Junction, Illinois)
The railroad also includes the:
Peoria Subdivision (Bureau Junction to Peoria, Illinois)
Cedar Rapids Subdivision (South Amana to Cedar Rapids, Iowa). This line is owned by the Cedar Rapids and Iowa City Railroad, but dispatched and operated by the Iowa Interstate.
The Iowa Interstate operates from Bureau to Chicago over the former Rock Island tracks controlled by CSX and Metra. In Chicago the IAIS owns two yard facilities, Burr Oak Yard and Evans Yard (the site of former rail car builder Evans), both in Blue Island, Illinois.
Trains are dispatched from the company's HQ in Cedar Rapids, Iowa, where a new dispatching office was completed in 2016. IAIS uses Wabtec's Train Management and Dispatching System (TMDS), the same dispatching software used by several Class I railroads, including the BNSF and KCS. When the IAIS took control of the track, the former Rock Island signal system was already damaged beyond repair due to sitting dormant for several years. Operations on the railroad are primarily controlled by track warrants rather than signals as a result.
The Iowa Interstate is unique in that it is the only Class II railroad in the US that has connections to every Class I railroad, affording its customers a reach not offered by other regional railroads.
The railroad also maintains two intermodal operations at either end of its line in Chicago and Council Bluffs. The operation in Council Bluffs is also used by the Union Pacific, with IAIS crews interchanging with UP several times a day.
IAIS subsidiary Rail Traffic Control formerly provided consulting services for dispatching and operating small- to medium-sized railroads worldwide.
In 2004, IAIS was awarded the E. H. Harriman Award for its safe operational record.
Amtrak
Beginning in the mid-1990s, the IAIS mainline has been identified as a potential route for high speedpassenger train service between Wyanet, Illinois (where the IAIS could be connected to the BNSF Railway), the Quad Cities and Iowa City, as part of the Midwest Regional Rail Initiative (MRRI). The ultimate goal of the MRRI is to establish passenger train routes in a hub-and-spoke formation with Chicago as the hub that allow for speeds up to and above 110 mph (177 km/h).
In July 2019, a new transportation bill was passed by the Illinois state legislature, supported by Governor J.B. Pritzker, $225M was appropriated to begin Amtrak service from Chicago to Moline, IL. A rail connector (junction) will be built between BNSF and IAIS to permit the Quad Cities service to use BNSF mainline from Wyanet to Chicago Union Station. This Amtrak route will use the IAIS main line between Wyanet and Moline, IL. Upgrades to IAIS rail crossings, track, and signaling for Amtrak's 79-mph requirements will be performed.[2]
Motive power
IAIS uses 42 locomotives and two slugs to power its trains:[3][4]
20 GE ES44AC (Numbered 500-519); unit 513 is painted in a Rock Island commemorative scheme; unit 516 is painted in a Rock Island inspired 30th anniversary paint scheme.
17 EMD GP38-2 (Numbered 700-703; 705; 707-708; 710-716; 718-719; 721) 720 was sold/leased to ADM in Des Moines, Iowa in 2017.
2 Slugs (Numbered 650 and 651) 601 and 650 are semi-permanently mated, as are 721 and 651
In 2006, IAIS also purchased two ex-China Railways QJ 2-10-2 steam locomotives, numbered 6988 and 7081 for special excursion trains and fundraising events. 6988 has been "Americanized", with a paint scheme inspired by Iowa Interstate's ES44AC locomotives. 7081 retains its original China Railways paint with Iowa Interstate badges. Both were later donated to Central States Steam Preservation Association.[5][6]
Since 2018, the 6988 has made several excursion trips to raise money for local volunteer fire departments and promote awareness of Operation Lifesaver. As of 2022, both 6988 and 7081 are out of service pending overhaul; the former is currently located at the Railroading Heritage of Midwest America in Silvis, Illinois.
