The History of the American Railroad with Albert Churella

Railroads have shaped America's growth, technology, and daily life for nearly two centuries. In this episode of AMSEcast, Alan talks with Dr. Albert Churella of Kennesaw State University about how innovations such as the automatic knuckle coupler, Westinghouse's air brake, and the move from steam to diesel transformed safety and efficiency. Dr. Churella explains how signaling, centralized traffic control, and GPS-based Positive Train Control modernized operations. While U.S. passenger service lags Europe, its freight rail system leads the world in ton-miles, fuel efficiency, and low emissions. Albert also previews his forthcoming book on Conrail, reflecting on the railroad industry's resilience, its economic impact, and its enduring relevance today.   About Dr. Albert Churella Dr. Albert Churella is a leading scholar of transportation history and policy with a particular focus on railroads.
