Missouri Railroads: A Modern Crossroads 1921-2023 delves into the rich history of Missouri''s railroads during their second century. From the roaring 1920s, when opulent "Limited" passenger trains crisscrossed the state, to the tumultuous times of the Great Depression and World War II, this book captures the essence of an era.
