Model Information: Properly weighted for superior tracking, the Trainworx Pullman Standard PS-2CD 4427 High Side Covered Hopper models have body mounted magnetic knuckle couplers, etched metal grab irons and roofwalks, three different trough hatch styles, jack pads (where appropriate), and 100 ton trucks with Fox Valley metal wheels.

Prototype History: Found throughout North America, these unique freight cars are commonly found in large groups near major carbon black producers or users. They can also be seen singularly or in small blocks of cars in mixed freight trains. Both prototypes were painstakingly researched from field documentation, photographs, reference books, and builder drawings.

In 1992, Thrall introduced the 4727 cubic foot carbon black covered hopper. In contrast with the boxy 5750cf design, this newer design more closely resembles traditional covered hoppers. Similar in appearance to “high-hip” grain hoppers, these cars featured three bays, external posts, and “open” ends with visible slope sheets. Common with their larger 5750cf cousins, these 70-ton cars feature “butterfly” outlets, multiple round loading hatches on the car roof (22 or 28 depending upon customer specifications), and sampling spigots mounted into small indents in the car sides. Many of these cars are still in service today.

A byproduct of the petrochemical refining industry, carbon black is a fine, powdery substance with a consistency sometimes described as being akin to soot. Deep black in color, one of its major consumers is the automotive industry, where it’s used as filler in tires, belts, and other rubber products. It also sees usage as a pigment in inks, paints, and plastic products, all of which make it a popular commodity with a variety of industries. Hauling it, however, can be challenging thanks to its physical properties. Covered hoppers are typically used to handle carbon black, with unique designs dating back to the 1920s.

Road Name History: The St. Louis - San Francisco Railway (reporting mark SLSF), also known as the Frisco, was a railroad that operated in the Midwest and South Central U.S. from 1876 to April 17, 1980. At the end of 1970 it operated 4,547 miles (7,318 km) of road on 6,574 miles (10,580 km) miles of track, not including subsidiaries Quanah, Acme and Pacific Railway or the Alabama, Tennessee and Northern Railroad; that year it reported 12,795 million ton-miles of revenue freight and no passengers. It was purchased and absorbed into the Burlington Northern Railroad in 1980.

The St. Louis - San Francisco Railway was incorporated in Missouri on September 7, 1876. It was formed from the Missouri Division and Central Division of the Atlantic and Pacific Railroad. This land grant line was one of two railroads (the other being the M-K-T) authorized to build across Indian Territory. The Atchison, Topeka and Santa Fe Railroad, ATSF, interested in the A & P right of way across the Mojave Desert to California, took the road over until the larger road went bankrupt in 1893; the receivers retained the western right of way but divested the ATSF of the St. Louis-San Francisco mileage on the great plains. After bankruptcy the Frisco emerged as the St. Louis and San Francisco Railroad, incorporated on June 29, 1896, which also went bankrupt. On August 24, 1916 the company was reorganized as the St. Louis - San Francisco Railway, though the line never went west of Texas, being more than 1,000 miles (1,600 km) from San Francisco.
