[1] Locomotives commonly known as "sharknoses" include: While the passenger models were unique to the Pennsylvania Railroad, other railroads purchased and operated the freight models, including the New York Central, Baltimore and Ohio and Elgin, Joliet & Eastern.
The New York Central was the last original owner to operate the engines, selling the last of them to the Monogahela Railway for $6,000 each in late 1967.
The final pair also were sold for scrap in 1974, but were rescued from the torch by the Delaware and Hudson Railroad, which at the time was also operating the world's last four Alco PA-1 passenger locomotives.
Both engines have purportedly been stored out of public view on the property of the Escanaba and Lake Superior Railroad for more than 20 years.
[citation needed][2] The name "sharknose" has also been given to streamlined automobiles of the 1930s and 1940s, because of their design, first introduced in 1936 on the 1937 Willys passenger cars.
