AZL - 91911-1 - Covered Hopper, 3-Bay, PS-2 - Southern - 88545

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 Southern Railway (reporting mark SOU) (also known as Southern Railway Company) was a US class 1 railroad that was based in the Southern United States. It was the product of nearly 150 predecessor lines that were combined, reorganized and recombined beginning in the 1830s, formally becoming the Southern Railway in 1894.

At the end of 1970 Southern operated 6,026 miles (9,698 km) of railroad, not including its Class I subsidiaries AGS (528 miles or 850 km) CofG (1729 miles) S&A (167 miles) CNOTP (415 miles) GS&F (454 miles) and twelve Class II subsidiaries. That year Southern itself reported 26111 million net ton-miles of revenue freight and 110 million passenger-miles; AGS reported 3854 and 11, CofG 3595 and 17, S&A 140 and 0, CNO&TP 4906 and 0.3, and GS&F 1431 and 0.3

The railroad joined forces with the Norfolk and Western Railway (N&W) in 1982 to form the Norfolk Southern Corporation. The Norfolk Southern Corporation was created in response to the creation of the CSX Corporation (its rail system was later transformed to CSX Transportation in 1986). The Southern Railway was renamed Norfolk Southern Railway in 1990 and continued under that name ever since. Seven years later in 1997 the railroad absorbed the Norfolk and Western Railway, ending the Norfolk and Western's existence as an independent railroad.
