Prototype Description: As covered hoppers evolved in the 1960s, larger cylindrical and rounded car bodies were introduced. This shape allowed more material to be carried and used gravity to force the load toward the bottom discharge outlets. Some of these designs also used pneumatic unloading systems. The continued demand for larger cars led Trinity Industries to introduce their new Power-Flo pressure differential (PD) hoppers in 1987. The design utilized proven technology by combining a pressurized system with rounded side walls. This allowed for increased payload, and reduced the time needed for loading and unloading.

Road Name History:
W.R. Grace and Company is an American chemical conglomerate based in Columbia, Maryland. Grace is divided into three business segments—Grace Catalysts Technologies, Grace Materials Technologies, and Grace Construction Products. Grace is a specialty chemicals and materials company. It has more than 6,700 employees in nearly 40 countries, and annual sales of more than US $ 2.5 billion. The company's stock, listed in 1953, trades on the New York Stock Exchange.

W.R. Grace and Company was founded in 1854, in Peru, by William Russell Grace, who left Ireland due to the potato famine, and traveled to South America with his father and family. He went first to Peru to work as a ship's chandler for the firm of Bryce and Company, to the merchantmen harvesting guano (bird droppings), used as a fertilizer and gunpowder ingredient due to its high levels of phosphorus and nitrogen.

His brother Michael joined the business and in 1865 the company name was changed to Grace Brothers & Co. The company set up head office operations in New York City in 1865. Working in fertilizer and machinery, the company was formally chartered in 1872, and incorporated in 1895.

The Davison Chemical Divison of W.R. Grace is based in Chicago, Illinois.

Brand/Importer Information:
Wm. K. Walthers, Inc., was founded in Milwaukee in 1932 -- but really, it started years earlier, when seven-year-old Bill Walthers got his first taste of the hobby with a small, wind-up toy train for Christmas. He continued with the hobby and eventually had an attic layout comprised primarily of his own scratch-built creations. After he wrote a series of articles on building train control and signaling systems, he got so many letters from other modelers that he began manufacturing them. The first ad (in the May issue of The Model Maker) offered a 24-page, 15c catalog that listed rail, couplers, and electrical supplies. Sales were over $500.00 for the first year, and the fledgling company was off to a strong start.

Within five years, Walthers had grown so much that larger quarters were needed. Space was found on Erie Street, where everything -- from milled wood parts to metal castings to decals -- was made in-house. 1937 also saw a new line in HO Scale, featured in its own catalog. Bill brought operating layouts to the 1939 World's Fair, which gave the hobby a big boost. Soon, though, the growing possibility of war overshadowed these successes, and supplies were becoming increasingly difficult to obtain.

During the war, model manufacturers were ordered to stop production in order to conserve critical metal supplies. Walthers produced what it could from nonessential materials. A series of ads in 1943 saw Bill literally scraping the bottom of a barrel! The postwar boom meant rapid growth for the hobby; however, small homes and new families left no room for O scale layouts, and many modelers moved to HO Scale.

The next twenty years brought great change. In 1958, Bill retired and his son Bruce took over. Just as full-size railroads were being hard-hit by new technology, so too were model railroads. Leisure time was spent in front of the TV set, not the train set. In 1960, Walthers became a full-line distributor of other manufacturers' products while continuing expansion of the Walthers lines. By the start of the 1970's, business was booming again, and Bruce's son Phil joined the company.

Expansion and diversification continue under Phil's tenure. The establishment of the Walthers Importing Division added several international lines. The manufacturing plant was modernized. Code 83 track was introduced in 1985, giving layouts more realistic proportions. In 1990, the Cornerstone Series buildings were unveiled. Combining a freight car with a related industry, the Cornerstone Series makes it possible for modelers to duplicate authentic operations, enhancing layout realism. The Train Line Deluxe Sets and locomotives debuted in 1994. These sets feature the detailing of serious models and an affordable price -- allowing newcomers to get started, and then build-on to their first set, rather than replacing it.

In 2005, Walthers purchased Life-Like from Lifoam Industries. With this purchase Walthers acquired the Proto Lines that have become the backbone of their locomotive and rolling stock segments.

Today, Walthers continues to expand, improve and develop a wide range of products. Their latest selection can be found throughout Walthers.com and their printed catalogs, along with items from over 300 other manufacturers.
