Open Hopper, 2-Bay, Composite

History: The story of these 2-Bay War Emergency Hoppers begins in 1942 when the War Production Board directed car builders to substitute wood for steel wherever possible in car superstructures. The familiar 2-Bay War Emergency Composite Hopper was a result of this directive. Those cars had wooden side sheets and end slope sheets (although the middle slope sheets remained steel.)

The wood siding was thicker than comparable steel sheeting and this reduced the capacity of the cars. While you could build ten composite cars with the steel from nine all-steel cars, it took more composite cars to move the same amount of coal. This combined with the more frequent repairs required by the composite cars soured the War Production Board on the design.

During 1944, the directive was set aside and cars that were on order were delivered with the familiar diagonal bracing but with all steel construction. After the war, as composite cars came due for serious maintenance, the wood side and slope sheets were replaced with steel. A large majority of the composite cars were rebuilt in this manner sometime during the 1950s.

Railroad/Company: The Pennsylvania Railroad (reporting mark PRR) was an American Class I railroad, founded in 1846. Commonly referred to as the "Pennsy," the PRR was headquartered in Philadelphia, Pennsylvania.

The PRR was the largest railroad by traffic and revenue in the U.S. for the first half of the twentieth century. Over the years, it acquired, merged with or owned part of at least 800 other rail lines and companies. At the end of 1925, it operated 10,515 miles of rail line; in the 1920s, it carried nearly three times the traffic as other railroads of comparable length, such as the Union Pacific or Atchison, Topeka & Santa Fe railroads. Its only formidable rival was the New York Central (NYC), which carried around three-quarters of PRR's ton-miles.

At one time, the PRR was the largest publicly traded corporation in the world, with a budget larger than that of the U.S. government and a workforce of about 250,000 people. The corporation still holds the record for the longest continuous dividend history: it paid out annual dividends to shareholders for more than 100 years in a row.

In 1968, PRR merged with rival NYC to form the Penn Central Transportation Company, which filed for bankruptcy within two years. The viable parts were transferred in 1976 to Conrail, which was itself broken up in 1999, with 58 percent of the system going to the Norfolk Southern Railway (NS), including nearly all of the former PRR. Amtrak received the electrified segment east of Harrisburg.
