Aerotrain (GM)

The Aerotrain was a streamlined trainset introduced by General Motors (GM) in 1955. Designed in response to declining passenger rail ridership in the United States, the Aerotrain aimed to revive interest in train travel with its futuristic styling and lightweight construction.

The train's distinctive design, created by GM's Electro-Motive Division (EMD), featured a low-slung, aerodynamic body inspired by aircraft design. Key elements included a single-unit EMD LWT12 diesel locomotive and passenger cars based on GM's bus technology, specifically using air suspension and large picture windows. The intent was to reduce manufacturing costs and offer a more comfortable ride.

Two Aerotrains were initially built. GM leased them to various railroads, including the New York Central, Pennsylvania, and Union Pacific, to test their viability on existing routes. While the trains attracted attention, they ultimately proved unsuccessful. The lightweight construction resulted in a rough ride at higher speeds, and maintenance costs were unexpectedly high. The unconventional styling, though initially appealing, eventually faced criticism.

By the late 1960s, both Aerotrains were retired from mainline service. One was scrapped, while the other was preserved and eventually found its way to the National Railroad Museum in Green Bay, Wisconsin. Despite its short lifespan, the Aerotrain remains a notable example of mid-century modern design and a reminder of the challenges faced by passenger rail travel during the rise of the automobile and air travel.
