The Pennsylvania Railroad (reporting mark PRR, legal name The Pennsylvania Railroad Company, also known as the "Pennsy") was an American Class I railroad that was established in 1846 and was headquartered in Philadelphia, Pennsylvania. It was so named because it was established in the Commonwealth of Pennsylvania. By 1882, the Pennsylvania Railroad had become the largest railroad (by traffic and revenue), the largest transportation enterprise, and the largest corporation in the world. Its budget was second only to the U.S. government. Over the years, it acquired, merged with or owned part of at least 800 other rail lines and companies.[2] At the end of 1926, it operated 11,640.66 miles (18,733.83 kilometres) of rail line;[notes 1][3] in the 1920s, it carried nearly three times the traffic as other railroads of comparable length, such as the Union Pacific and Atchison, Topeka & Santa Fe railroads. Its only formidable rival was the New York Central (NYC), which carried around three-quarters of the Pennsy's tonne-miles.
