Use of Railroad Flat Cars for Low-Volume Road Bridges, August 1999

In an attempt to solve the bridge problem faced by many county engineers, this investigation focused on a low cost bridge alternative that consists of using railroad flatcars (RRFC) as the bridge superstructure. The intent of this study was to determine whether these types of bridges are structurally adequate and potentially feasible for use on low volume roads. A questionnaire was sent to the Bridge Committee members of the American Association of State Highway and Transportation Officials (AASHTO) to determine their use of RRFC bridges and to assess the pros and cons of these bridges based on others’ experiences. It was found that these types of bridges are widely used in many states with large rural populations and they are reported to be a viable bridge alternative due to their low cost, quick and easy installation, and low maintenance. A main focus of this investigation was to study an existing RRFC bridge that is located in Tama County, IA. This bridge was analyzed using computer modeling and field load testing. The dimensions of the major structural members of the flatcars in this bridge were measured and their properties calculated and used in an analytical grillage model. The analytical results were compared with those obtained in the field tests, which involved instrumenting the bridge and loading it with a fully loaded rear tandem-axle truck. Both sets of data (experimental and theoretical) show that the Tama County Bridge (TCB) experienced very low strains and deflections when loaded and the RRFCs appeared to be structurally adequate to serve as a bridge superstructure. A calculated load rating of the TCB agrees with this conclusion. Because many different types of flatcars exist, other flatcars were modeled and analyzed. It was very difficult to obtain the structural plans of RRFCs; thus, only two additional flatcars were analyzed. The results of these analyses also yielded very low strains and displacements. Taking into account the experiences of other states, the inspection of several RRFC bridges in Oklahoma, the field test and computer analysis of the TCB, and the computer analysis of two additional flatcars, RRFC bridges appear to provide a safe and feasible bridge alternative for low volume roads.

Cedar-Iowa River Rail Transit Project Feasibility Study, November 9, 2006

Five Seasons Transportation & Parking (FSTP) and the Johnson County Council of Governments (JCCOG) are interested in evaluating the feasibility of prospective passenger rail service(s) that would operate over existing trackage of the Cedar Rapids and Iowa City Railway Company (CRANDIC), seen below left, and/or the Iowa Interstate Railroad System (IAIS), seen below right, connecting Cedar Rapids, Iowa City and the Amana Colonies. To perform the study, FSTP and JCCOG selected R.L. Banks & Associates, Inc. (RLBA) as Prime Contractors, HNTB Corporation (HNTB) and Snyder & Associates, Inc. (Snyder) as Subcontractors, hereafter Consultant Team. Both railroads participated in the study and contributed time and resources, as did many local government and civic organizations. The purpose of the study is to determine whether it is feasible to establish regularly scheduled passenger rail service and/or special event excursion rail service, in conjunction with the Five Seasons Transit system, Iowa City Transit, East Central Iowa Transit, Coralville Transit and the University of Iowa CAMBUS.

2009 Iowa Railroad System Plan, 2009

The 2009 Iowa Railroad System Plan is intended to guide the Iowa Department of Transportation (DOT) in its activities of promoting access to rail transportation, helping to improve the freight railroad transportation system, expanding passenger rail service, and promoting improved safety both on the rail system and where the rail system interacts with people and other transportation modes. The Iowa DOT has been developing railroad transportation plans since the late 1970s. The original plan was prepared in 1978 during a time of crisis in the Iowa railroad system. Several large Iowa railroad carriers had filed for bankruptcy and were reorganizing both their businesses and physical systems. The 1978 plan was a guide for determining which railroad lines the state would partner with to preserve and improve the lines. In the 1970s, 1980s and 1990s, the railroad system mileage in Iowa was reduced from about

Part I. Iowa Railroad Investment Plan, 2009

The 2009 Iowa Railroad System Plan details the state’s role in providing and preserving adequate, safe and efficient rail transportation services to Iowans. The plan is intended to serve as a guide for decision makers and provides a basis for future Iowa DOT policy, funding priorities and programming decisions that affect rail transportation service in Iowa. The primary purpose of the 2009 Iowa Railroad System Plan is to guide the Iowa DOT in pursuing actions that maintain and improve railroad transportation in Iowa. The plan is a component of the Iowa Statewide Transportation Plan known as “Iowa in Motion.” This plan considers railroads from an intermodal perspective. Many commodities that move by rail also move by other modes (principally trucks) during part of their journey from origin to destination. The same is true of persons who use rail passenger service to make trips and who must also rely on other modes to access rail service. Therefore, railroads are part of larger intermodal freight and passenger transportation systems.
