AZL - 91931-1 - Covered Hopper, 3-Bay, PS-2 - Norfolk & Western - 177304

Model Information: Covered hoppers are designed for carrying dry bulk loads, varying from grain to products such as sand and clay. The cover protects the loads from the weather. Similar to an open hopper car, covered hoppers tend to contain 2, 3 or 4 separated bays. Each of these can be loaded and emptied individually, with access at the top to load the materials and visible chutes at the bottom for unloading.
Hoppers with 2, 3 or 4 bays are used for different purposes: 2 bay hoppers are used for the most dense loads (such as sand), while 4 bay hoppers are more suited to lighter loads. This is due to axle load limits, for example dry cement is very heavy in bulk quantities and a 4-bay hopper of sand would be very likely to exceed these limits while also having problems with increased strain upon the central span. By trading off cubic capacity 2 bay hoppers are able to transport these heavy loads. As technology has advanced, some of the heavier loads formerly assigned to 2-bay hoppers have been assigned to larger, more efficient 3-bay hoppers.

Prototype History: Like their PS-1 boxcars, PS-5 gondolas and other car designs, Pullman Standard applied the PS-2 classification to all of its covered hoppers. Pullman Standard built covered hoppers in many sizes and configurations. But say “PS-2” to railfans and it is this particular car that usually first comes to mind. The 2003 cubic foot car was one of the first, smallest and prolific of the PS-2 cars.

Pullman began building its standardized freight car designs with the PS-1 boxcar in 1947. Next up would be a standard covered hopper – hence PS-2 – shortly thereafter. Although covered hoppers are among the most common cars on the rails today, in 1947 they were a rarity. The PS-2’s primary competition wasn’t other covered hopper designs but boxcars. Grain, cement, sand and dried chemicals were carried mostly in boxcars prior to the 1950s either in sacks and bags or poured in bulk through hatches in the roof. The theory here was that it made more sense to utilize a single car for a variety of products. The car could carry bags of cement one way and then cut lumber the other. Of course a car that could do many things often couldn’t do many of them well.

Road Name History: The Norfolk and Western Railway (reporting mark NW), was a US class I railroad, formed by more than 200 railroad mergers between 1838 and 1982. It was headquartered in Roanoke, Virginia, for most of its 150-year existence. Its motto was "Precision Transportation"; it had a variety of nicknames, including "King Coal" and "British Railway of America" even though the N&W had mostly articulated steam on its roster. During the Civil War, the N&W was the biggest railroad in the south and moved most of the products with their steam locomotives to help the South the best way they could.

NW was famous for manufacturing its own steam locomotives, which were produced at the Roanoke Shops, as well as its own hopper cars. Around 1960, NW became the last major American railroad to convert from steam locomotives to diesel motive power but didn't retire its last remaining Y class locomotives until 1964 and 1965. By 1965, steam on class I railroads was gone but steam wasn't gone on class II railroads until 1974 and class III and mining railroads retired their steam locomotives from their active roster until 1983. By 1983, steam in America on class I, II, III, and mining railroads had finally closed the chapter on America's 150 years of steam from 1830 - 1983.

In December 1959, NW merged with the Virginian Railway (reporting mark VGN), a longtime rival in the Pocahontas coal region. By 1970, other mergers with the Nickel Plate Road and Wabash formed a system that operated 7,595 miles (12,223 km) of road on 14,881 miles (23,949 km) of track from North Carolina to New York and from Virginia to Iowa.

In 1980, NW teamed up with the Southern Railway, another profitable carrier and created the Norfolk Southern Corporation holding company by merging its business operations with the business operations of the Southern Railway. The NW and the Southern Railway continued as separate railroads now under one holding company.

On December 31, 1990, the Southern Railway was renamed "Norfolk Southern Railway" to reflect the Norfolk Southern Corporation and on the same day, the renamed Norfolk Southern Railway gained full control of the Norfolk and Western Railway with the Norfolk and Western being transferred from the holding company to the renamed Norfolk Southern Railway, this began the final years of Norfolk and Western which was absorbed into the renamed Norfolk Southern Railway seven years later in 1997 (1990 to 1997 the Norfolk and Western continued operating by using paper operations).

In 1997 during the Conrail battle with CSX, Norfolk Southern Corporation's principal railroad, the renamed Norfolk Southern Railway, absorbed the Norfolk and Western Railway into their rail system, ending the existence of the Norfolk and Western Railway and having the renamed Norfolk Southern Railway becoming the only railroad in the entire Norfolk Southern system after that.
