2009 Iowa’s Rail System Background Prepared by the Office of Systems Planning December 2010

Iowa’s Rail Environment Iowa’s rail transportation system provides both freight and passenger service. Rail serves a variety of trips, including those within Iowa and those to other states as well as to foreign markets. While rail competes with other modes, it also cooperates with those modes to provide intermodal services to Iowans. In 2009 Iowa’s rail transportation system could be described as follows: Freight Iowa’s 130,000-mile freight transportation system includes an extensive railroad network, a well-developed highway system, two bordering navigable waterways, and a pipeline network as well as air cargo facilities. While rail accounts for only 3 percent of the freight network, it carries 43 percent of Iowa’s freight tonnage. A great variety of commodities ranging from fresh fish to textiles to optical products are moved by rail. However, most of the Iowa rail shipments consist of bulk commodities, including grain, grain products, coal, ethanol, and fertilizers. The railroad network performs an important role in moving bulk commodities produced and consumed in the state to local processors, livestock feeders, river terminals and ports for foreign export. The railroad’s ability to haul large volumes, long distances at low costs will continue to be a major factor in moving freight and improving the economy of Iowa. Key 2008 Facts • 3,945 miles of track • 18 railroads • 49.5 million tons shipped • 39.7 million tons received • 2 Amtrak routes • 6 Amtrak stations • 66,286 rail passenger rides Key Rail Trends • slightly fewer miles being operated; • railroads serving Iowa has remained the same; • more rail freight traffic; • more tons hauled per car; • higher average rail rates per ton-mile since 2002; • more car and tons hauled per locomotive; and • more ton miles per gallon of fuel consumed. Iowa’s rail system and service has been evolving over time relative to its size, financial conditions, and competition from other modes.

Iowa Highway Research Board TR-423: 1949–1999, 1999

The year 1949 saw the Iowa General Assembly’s establishment of the Iowa Secondary Road Research Fund, which led to the creation of a supervisory board within what was then the Iowa State Highway Commission to oversee the expenditure of that fund. The purpose of the fund and the board was to research road construction topics likely to be beneficial to the working of Iowa’s secondary, or local, road system. The supervisory board—called the Iowa Highway Research Board (the “Board”)—was organized by the highway commission in December 1949 and first met in May 1950. The creation of the fund and of the Iowa Highway Research Board marked the first organized effort in the United States to investigate local road construction problems and placed Iowa in the forefront of this field of engineering research. That Iowa should be a leader in such an effort is not surprising, given the early and sustained emphasis of the Iowa State Highway Commission on both research and the dissemination of information to county authorities. Now, 50 years later, a retrospective is in order. To that end, the Iowa Highway Research Board commissioned the preparation of a commemorative history. This work is the result of that project. Throughout its existence, the Board has funded nearly 450 projects, several of national significance. Many new construction and maintenance techniques have been developed, some of which have evolved into standard practices in highway construction. Innovative new materials and equipment have been tested. Still other projects have considered a wide variety of subjects related to the efficient operation of the highway system. Highway safety, conservation, and law have all come under research scrutiny. While it will not be possible, given the short space available, to consider all the projects financed by the Iowa Highway Research Board, it is well worthwhile to examine the Board’s principal projects and its resulting contributions to the field of highway research.

Annual Report of Iowa Highway Research Board Research and Development Activities FY 2011, December 2011

The Highway Division of the Iowa DOT engages in research and development for two reasons: first, to find workable solutions to the many problems that require more than ordinary, routine investigation; and second, to identify and implement improved engineering and management practices. This report, entitled ―Iowa Highway Research Board Research and Development Activities FY2011‖ is submitted in compliance with Sections 310.36 and 312.3A, Code of Iowa, which direct the submission of a report of the Secondary Road Research Fund and the Street Research Fund, respectively. It is a report of the status of research and development projects in progress on June 30, 2011. It is also a report on projects completed during the fiscal year beginning July 1, 2010 and ending June 30, 2011. Detailed information on each of the research and development projects mentioned in this report is available from the Research and Technology Bureau, Highway Division, Iowa Department of Transportation. All approved reports are also online for viewing at: www.iowadot.gov/operationsresearch/reports.aspx.

On The Spot Damage Detection Methodology for Highway Bridges, July 2010

Vibration-based damage identification (VBDI) techniques have been developed in part to address the problems associated with an aging civil infrastructure. To assess the potential of VBDI as it applies to highway bridges in Iowa, three applications of VBDI techniques were considered in this study: numerical simulation, laboratory structures, and field structures. VBDI techniques were found to be highly capable of locating and quantifying damage in numerical simulations. These same techniques were found to be accurate in locating various types of damage in a laboratory setting with actual structures. Although there is the potential for these techniques to quantify damage in a laboratory setting, the ability of the methods to quantify low-level damage in the laboratory is not robust. When applying these techniques to an actual bridge, it was found that some traditional applications of VBDI methods are capable of describing the global behavior of the structure but are most likely not suited for the identification of typical damage scenarios found in civil infrastructure. Measurement noise, boundary conditions, complications due to substructures and multiple material types, and transducer sensitivity make it very difficult for present VBDI techniques to identify, much less quantify, highly localized damage (such as small cracks and minor changes in thickness). However, while investigating VBDI techniques in the field, it was found that if the frequency-domain response of the structure can be generated from operating traffic load, the structural response can be animated and used to develop a holistic view of the bridge’s response to various automobile loadings. By animating the response of a field bridge, concrete cracking (in the abutment and deck) was correlated with structural motion and problem frequencies (i.e., those that cause significant torsion or tension-compression at beam ends) were identified. Furthermore, a frequency-domain study of operational traffic was used to identify both common and extreme frequencies for a given structure and loading. Common traffic frequencies can be compared to problem frequencies so that cost-effective, preventative solutions (either structural or usage-based) can be developed for a wide range of IDOT bridges. Further work should (1) perfect the process of collecting high-quality operational frequency response data; (2) expand and simplify the process of correlating frequency response animations with damage; and (3) develop efficient, economical, preemptive solutions to common damage types.

Highway Relocation: U.S. 30/Lincoln Highway film production, 1960

The film depicts period traffic congestion, sharp and winding sections of road, steep hills making trucks slow to a crawl, and dangerous vehicle and pedestrian crossings, all important reasons why highway design and safety improvements, and highway relocation were needed. In fact, when the film was produced, U.S. 30 or the Lincoln Highway was the busiest primary road in Iowa; and the section between State Center and Boone was deemed “critical,” meaning it was considered dangerous by the ISHC’s Efficiency Standards.
