Model Power - 3474 - Covered Hopper, 4-Bay, ACF Centerflow - Rio Grande - 15525

Model Information: This tooling is a Chinese made knockoff of the Roco 'Centerflow' hopper that was originally imported by Atlas. The Roco model can be distinguished by the presence of 'Austria' stamped into the underframe.

Prototype History: Contemporary 2-bay covered hoppers, like ACF's Centerflows, were 100-ton cars designed to haul dense loads, like cement. Their larger 3 and 4-bay brethren, while usually still having 100 ton capacities, were designed for lighter-density loads, like grain or flour. Their sizes had to do with the fact that a low-density product like grain will "cube out" the cubic capacity of a smaller 2-bay car way before you hit the cars' tonnage rating. Conversely, load a 3 or 4-bay covered hopper to its cubic maximum with a dense product like cement, and you'll wind up with a seriously overloaded car tonnage wise. In short, keep the smaller 2-bay cars for heavy commodities, and keep the larger cars for lighter loads like grains, sugar, flour, etc.

Road Name History: The Denver & Rio Grande Western Railroad (reporting mark DRGW), often shortened to Rio Grande, D&RG or D&RGW, formerly the Denver & Rio Grande Railroad, was an American Class I railroad company. The railroad started as a 3 ft (914 mm) narrow gauge line running south from Denver, Colorado in 1870. It served mainly as a transcontinental bridge line between Denver, and Salt Lake City, Utah.

In 1988, the Rio Grande's parent corporation, Rio Grande Industries, purchased Southern Pacific Transportation Company, and as the result of a merger, the larger Southern Pacific Railroad name was chosen for identity. The Rio Grande operated as a separate division of the Southern Pacific, until that company was acquired by the Union Pacific Railroad. Today, most former D&RGW main lines are owned and operated by the Union Pacific while several branch lines are now operated as heritage railways by various companies.
