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 Union Pacific Railroad (reporting mark UP) is a freight hauling railroad that operates 8,500 locomotives over 32,100 route-miles in 23 states west of Chicago, Illinois and New Orleans, Louisiana. The Union Pacific Railroad network is the largest in the United States and employs 42,600 people. It is also one of the world's largest transportation companies.

Union Pacific Railroad is the principal operating company of Union Pacific Corporation (NYSE: UNP); both are headquartered in Omaha, Nebraska. Over the years Union Pacific Corporation has grown by acquiring other railroads, notably the Missouri Pacific, Chicago & North Western, Western Pacific, Missouri-Kansas-Texas, and the Southern Pacific (including the Denver & Rio Grande Western).

Union Pacific Corporation's main competitor is the BNSF Railway, the nation's second largest freight railroad, which also primarily services the Continental U.S. west of the Mississippi River. Together, the two railroads have a duopoly on all transcontinental freight rail lines in the U.S.
