Adventures in Electricity #5

An educational narrative about the history and development of electric railroads in America, tracing the evolution from Edison's early electric ride in 1888 through the expansion of electrified rail systems across the country. The story follows a character named Johnny as he learns about major electric locomotive achievements, including the Milwaukee Road's powerful electric locomotives used to haul freight over the Cascade Mountains and the "Virginian," described as the largest single-car electric locomotive built for the Great Northern Railway's Cascade Tunnel section. The narrative emphasizes the flexibility and power of diesel-electric locomotives, which can use multiple motor units to generate the necessary horsepower for heavy freight transportation, and concludes by noting ongoing developments in electric railroad technology including gas turbines and other new designs.
