The New Frederick Douglass Tunnel – Improving Amtrak Services

The 150-year-old Baltimore and Potomac Tunnel, Amtrak’s oldest, carries traffic for Amtrak, the Maryland Area Rail Commuter (MARC) Service, as well as Norfolk Southern freight operations. This tunnel is a major bottleneck for Northeast corridor rail traffic, and Amtrak is rebuilding it and adding a new, passenger-only tunnel named after abolitionist Frederick Douglass.In this podcast we learn about this large program from Mark Milton, Senior Director, Capital Delivery for Amtrak, who is managing final design and construction for the overall program. Mark’s a civil engineer with many years of experience in design.[Correction to interview conversation: all railroad grades on this project are less than 2.0%

Causes and Prevention of Train Derailments

US railroads are highly efficient at moving freight. Indeed, our freight rail system is the envy of the world, but sometimes accidents occur. When train derailments occur, the outcome is usually minor, but occasionally more serious problems arise.To understand the causes and prevention of train derailments, we’re talking with Dr. Allan Zarembski, Professor of Practice and Director of the Railroad Engineering and Safety Program at the University of Delaware. He’s an expert on railroad track engineering, safety, and derailment analysis

Mass Timber Buildings – New Ways to Build with an Old Material

Wood has been perhaps the most common material for buildings for millennia, but innovations in its application are bringing new opportunities and advantages for working with this sustainable material. Structural applications of mass timber are proliferating in types and scales. Factory assembly of wood components can produce stronger elements in designed architectural shapes.To find out more about the characteristics and benefits of new uses of wood for infrastructure, we talk with Eric Long, Structural Engineering Partner at Skidmore, Owings & Merrill in San Francisco, who leads the firm’s West Coast Structural Engineering practice.

Insuring Infrastructure Against Climate Change

Changing climate brings new risks to infrastructure, and commonly these risks are shared with insurance companies. To control their risks, insurers need to understand and anticipate both the sources and characteristics of natural threats, and to collaborate with their clients – infrastructure owners and operators – to mitigate the risks of natural hazards.To open a window on the role of insurers in addressing climate risk, we talk with Martin Lockman, a research lawyer working at Columbia University’s Sabin Center for Climate Change Law. Martin works at the intersection of climate-related threats to infrastructure, the insurance industry, and risk management

Transforming Commuter Rail Services for a Post-COVID Market

COVID-19 has robbed public transit of riders as many have changed workplaces, shifted schedules, and chosen new ways to travel to avoid crowds. Transit operators around the world are working to attract commuters back, adjusting services and fares to accommodate changing markets, secure reliable revenue sources, and redefine their roles in the city.To tell us more about both the challenges and responses of a major commuter rail operator, we’ve invited James Derwinski to talk with us. Jim is CEO and Executive Director of Metra, the commuter rail system serving the Chicago Metropolitan area, the fourth largest in the US in terms of trips carried, and the largest in terms of route miles

Rural Transit Meets Big Challenges

Mobility is essential for the well-being of people wherever they live. The automobile is king of the mobility market across the US, but public transit supports mobility for those who cannot, or chose not to, travel by car. The need for alternatives to automobility in smaller communities and rural areas is substantial but not especially visible.To understand the role and options for transit in such places, we talk with Scott Brogen, who is Executive Director of the Community Transportation Association of America

Overheated Infrastructure

A hotter climate brings new challenges to the built infrastructure, stressing service systems – power generation and distribution and transportation systems – as well as structures. Are we prepared for these problems? How can infrastructure adapt to higher temperatures?To understand both the problems and options, we talk with Mikhail Chester, Associate Professor in the School of Sustainable Engineering and the Built Environment at the Fulton School of Engineering, and Director of the Metis Center for Infrastructure and Sustainable Engineering, at Arizona State University

Restoring a Superfund Site

Superfund sites are seriously polluted locations that are subject to remediation by the Environmental Protection Agency under the 1980 Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). These clean-up processes can be large, complex, and costly.To understand what it takes to restore a particularly challenging location, the 132-acre Eagle Zinc Superfund site in Hillsboro, Illinois, we talk with the EPA’s Margaret Gielniewski, who is Remedial Project Manager

Lighting Up the Farms

This podcast is a timely history lesson about the electrification of rural America and the Depression-era program that made it happen. The Rural Electrification Act of 1936 – the REA – provided federal loans to install electrical distribution systems to serve rural areas. The REA may offer lessons as we invest to extend high speed broadband service across the country.To learn about the REA and its impacts, we’re talking with Price Fishback, APS Professor of Economics at the Eller College of Management of the University of Arizona, an expert on the political economy of Roosevelt’s New Deal during the 1930s

Keeping the Port of Virginia Flowing

Marine ports are gateways to world trade, and their efficient functioning is a pillar of our economy. East and Gulf Coast ports have grown more important in recent years because of the expanded Panama Canal locks opened in 2016 and continuing congestion in West Coast ports and overland transportation. The Port of Virginia has been making important infrastructure investments to secure its position in this competition for world trade.To learn how it became the second busiest container port on the East Coast, in this podcast we talk with Stephen Edwards, CEO and Executive Director of the Virginia Port Authority (VPA)
