Specific Item Information: Road Numbers: 496472, 496482, 496483, 496496

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.

Road Name History: The Southern Pacific Transportation Company (reporting mark SP), earlier Southern Pacific Railroad and Southern Pacific Company, and usually called the Southern Pacific or (from the railroad's initials) Espee, was an American Class I railroad. It was absorbed in 1988 by the company that controlled the Denver and Rio Grande Western Railroad and eight years later became part of the Union Pacific Railroad.

The railroad was founded as a land holding company in 1865, later acquiring the Central Pacific Railroad by lease. By 1900 the Southern Pacific Company was a major railroad system incorporating many smaller companies, such as the Texas and New Orleans Railroad and Morgan's Louisiana and Texas Railroad. It extended from New Orleans through Texas to El Paso, across New Mexico and through Tucson, to Los Angeles, through most of California, including San Francisco and Sacramento. Central Pacific lines extended east across Nevada to Ogden, Utah, and reached north through Oregon to Portland. Other subsidiaries eventually included the St. Louis Southwestern Railway (Cotton Belt), the Northwestern Pacific Railroad at 328 miles (528 km), the 1,331 miles (2,142 km) Southern Pacific Railroad of Mexico, and a variety of 3 ft (914 mm) narrow gauge routes.

In 1929 SP/T&NO operated 13848 route-miles not including Cotton Belt, whose purchase of the Golden State Route circa 1980 nearly doubled its size to 3,085 miles (4,965 km), bringing total SP/SSW mileage to around 13,508 miles (21,739 km).

By the 1980s route mileage had dropped to 10,423 miles (16,774 km), mainly due to the pruning of branch lines. In 1988 the Southern Pacific was taken over by D&RGW parent Rio Grande Industries. The combined railroad kept the Southern Pacific name due to its brand recognition in the railroad industry and with customers of both constituent railroads. Along with the addition of the SPCSL Corporation route from Chicago to St. Louis, the total length of the D&RGW/SP/SSW system was 15,959 miles (25,684 km).

By 1996 years of financial problems had dropped SP's mileage to 13,715 miles (22,072 km), and it was taken over by the Union Pacific Railroad.
