Delaware Valley - 2421 - Covered Hopper, 2-Bay, GATX Airslide 4180 - Rock Island - 8920

Model Information: This model was originally created by Delaware Valley. It was later acquired by Bowser. It has also been used by Eastern Seaboard Models models.

Prototype History: The first Airslide covered hopper was introduced by General American Transportation Corporation (GATX) in 1953 and had a capacity of 2600 cubic feet. The Airslide is primarily designed for the bulk shipment of dry, granular or powdered commodities. The design of that car is such that it can be loaded and unloaded quickly and with little spillage through the use of air pressure. The most common commodities carried include: flour, sugar, starch, plastic pellets, cement, powdered chemicals and carbon black.

Due to customer demand for larger covered hoppers capable of handling bulk commodities, General American Transportation Corporation introduced the larger 4180 c.f. model in 1963. GATX produced more than 5,000 of the 4180 cubic foot Airslide covered hoppers between 1963 and 1980. These very common cars continued General American’s “Airslide” family innovations from the 1950s, and proved valuable to bulk shippers who wanted a larger car than the earlier-design 2600 cubic foot cars provided.

Road Name History: The Chicago, Rock Island and Pacific Railroad (CRI&P RR) (reporting marks RI, ROCK) was a Class I railroad in the United States. It was better known as the Rock Island Line, or, in its final years, The Rock. At the end of 1970 it operated 7183 miles of road on 10669 miles of track; that year it reported 20557 million ton-miles of revenue freight and 118 million passenger-miles. (Those totals may or may not include the former Burlington-Rock Island Railroad.)

Its predecessor, the Rock Island and La Salle Railroad Company, was incorporated in Illinois on February 27, 1847, and an amended charter was approved on February 7, 1851, as the Chicago and Rock Island Railroad. Construction began October 1, 1851, in Chicago, and the first train was operated on October 10, 1852, between Chicago and Joliet. Construction continued on through La Salle, and Rock Island was reached on February 22, 1854, becoming the first railroad to connect Chicago with the Mississippi River.

In 1980 Rock Island was liquidated. The railroad's locomotives, rail cars, equipment, tracks, and real estate were sold to other railroads or to scrappers. William Gibbons (the trustee) was able to raise more than $500 million in the liquidation, paying off all the railroad's creditors, bondholders and all other debts in full at face value with interest. Henry Crown was ultimately proven correct, as both he and other bondholders who had purchased Rock Island debt for cents on the dollar during the low ebb in prices did especially well.
