Prototype History: The late 1920s saw the introduction of the AAR standard “offset-side” 50- and 70-ton hoppers. The design went through several variations in the late 1920s and early 1930s before settling on two versions of the 50-ton car and one 3-bay, 70-ton car in 1935. Most roads went for the AAR standard designs, but the N&W, VGN, and Pennsy were notable holdouts. World War II brought the famous “war emergency” hoppers (only the N&W and MP bought the 70-ton version) and several composite versions of existing designs. After the war, AC&F found some brief success with a welded outside-stake hopper design, but the weld joints broke under the stress of loading and unloading rather than flexing like riveted joints. The offset-side design also had problems: the inside stakes were more prone to corrosion, and they suffered worse from loading and unloading stress than outside-staked hoppers. The design waned in the 1950s and was all but abandoned for new cars by 1960. Some roads (notably the C&O, the B&O, and the L&N) made the best of a bad situation by rebuilding their offset-side cars with all new outside-staked sides in the late 1950s and early 1960s.

Road Name History: 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.

Brand/Importer Information: Micro-Trains Line split off from Kadee Quality Products in 1990. Kadee Quality Products originally got involved in N-Scale by producing a scaled-down version of their successful HO Magne-Matic knuckle coupler system. This coupler was superior to the ubiquitous 'Rapido' style coupler due to two primary factors: superior realistic appearance and the ability to automatically uncouple when stopped over a magnet embedded in a section of track. The success of these couplers in N-Scale quickly translated to the production of trucks, wheels and in 1972 a release of ready-to-run box cars.

Micro-Trains Line Co. split off from Kadee in 1990 to form a completely independent company. For this reason, products from this company can appear with labels from both enterprises. Due to the nature of production idiosyncrasies and various random factors, the rolling stock from Micro-Trains can have all sorts of interesting variations in both their packaging as well as the products themselves. When acquiring an MTL product it is very important to understand these important production variations that can greatly enhance (or decrease) the value of your purchase.
