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 Seaboard Coast Line Railroad (reporting mark SCL) is a former Class I railroad company operating in the Southeastern United States beginning in 1967. Its passenger operations were taken over by Amtrak in 1971. Eventually the railroad was merged with its affiliate lines to create the Seaboard System in 1983.
At the end of 1970 SCL operated 9230 miles of railroad, not including A&WP-Clinchfield-CN&L-GM-Georgia-L&N-Carrollton; that year it reported 31293 million ton-miles of revenue freight and 512 million passenger-miles.
The Seaboard Coast Line emerged on July 1, 1967, following the merger of the Seaboard Air Line Railroad with the Atlantic Coast Line Railroad. The combined system totaled 9,809 miles (15,786 km), the eighth largest in the United States at the time. The railroad had $1.2 billion in assets and revenue with a 54% market share of rail service in the Southeast, facing competition primarily from the Southern.
On November 1, 1980, CSX Corporation was created as a holding company for the Family Lines and Chessie System Railroad. In 1983 CSX combined the Family Lines System units as the Seaboard System Railroad and later became CSX Transportation when the former Chessie units merged with the Seaboard in December 1986. Effective January 1, 1983, the Seaboard Coast Line Railroad became Seaboard System Railroad after a merger with the Louisville and Nashville Railroad and Clinchfield Railroad. For some years prior to this, the SCL and L&N had been under the common ownership of a holding company, Seaboard Coast Line Industries (SCLI), the company's railroad subsidiaries being collectively known as the Family Lines System which consisted of the L&N, SCL, Clinchfield and West Point Routes. During this time, the railroads adopted the same paint schemes but continued to operate as separate railroads.
