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 Canadian National Railway Company (reporting mark CN) is a Canadian Class I railway headquartered in Montreal, Quebec that serves Canada and the Midwestern and Southern United States. CN's slogan is "North America's Railroad". CN is a public company with 24,000 employees. It had a market capitalization of 32 billion CAD in 2011. CN was government-owned, having been a Canadian Crown corporation from its founding to its privatization in 1995. Bill Gates was, in 2011, the largest single shareholder of CN stock.

CN is the largest railway in Canada, in terms of both revenue and the physical size of its rail network, and is currently Canada's only transcontinental railway company, spanning Canada from the Atlantic coast in Nova Scotia to the Pacific coast in British Columbia. Its range once reached across the island of Newfoundland until 1988, when the Newfoundland Railway was abandoned.

Following CN's purchase of Illinois Central (IC) and a number of smaller US railways, it also has extensive trackage in the central United States along the Mississippi River valley from the Great Lakes to the Gulf of Mexico. Today, CN owns about 20,400 route miles (32,831 km) of track in 8 provinces (the only two not served by CN are Newfoundland & Labrador and Prince Edward Island), as well as a 70-mile (113 km) stretch of track (see Mackenzie Northern Railway) into the Northwest Territories to Hay River on the southern shore of Great Slave Lake; it is the northernmost rail line anywhere within the North American Rail Network, as far north as Anchorage, Alaska (although the Alaska Railroad goes further north than this, it is isolated from the rest of the rail network).

The railway was referred to as the Canadian National Railways (CNR) between 1918 and 1960, and as Canadian National/Canadien National (CN) from 1960 to the present.
