Chicago to Quad Cities – Grade Crossing Design

The Chicago to Quad Cities – Grade Crossing Design project is part of an engineering study for the Illinois Department of Transportation to establish Passenger Rail Service between Chicago and Iowa City. The Grade Crossing Design portion of the project investigates the recommended improvements to provide safe at-grade roadway and rail crossings.  Investigations included horizontal and vertical geometric studies, the addition and upgrade of crossing warning devices, the type materials to be used at the crossings, and the interconnection of traffic signals to crossing gates.

Services Provided


Project teams provided engineering services for the highway portion of the project focusing on the highway-rail grade crossings that need improvement to accommodate passenger rail service while safely accounting for the flow of vehicular traffic. As part of the Preliminary Engineering process, Designers are preparing Warrant 9 analysis where required, and Preliminary Engineering drawings for all at-grade crossings within the corridor. Design teams are focusing on completing 72 “30% concept level” plans and reports for the grade crossings. Many crossings will require development of multiple alternative designs that will be reviewed and analyzed for safety, cost, and performance.

Project Management

The project provides Program Management along with planning and preliminary engineering services for the Illinois Department of Transportation to implement passenger rail service on the Chicago to Iowa City corridor within the State of Illinois project limits. The Chicago-Iowa City Passenger Rail Service Development Program of Iowa and Illinois will establish passenger rail service between Chicago, the Quad Cities, Illinois and Iowa City, Iowa, 219.5 miles. The service will be hosted by BNSF Railway (BNSF) and Iowa Interstate Railroad (IAIS), and be operated by Amtrak. New stations will be established at Geneseo and Moline, Illinois (serving the Quad Cities); and Iowa City, Iowa. The service will be part of the Midwest Regional Rail Imitative (MWRRI) designated by the Secretary of Transportation as a high-speed rail corridor in 1992.
