Road Name History: Hooker Chemical Company was an American chemical company that produced chlor-alkali products from 1903 to 1968. In 1922, Hooker bought the S. Wander & Sons company for the retail sales of lye and chlorinated lime. Hooker Chemical is best known for the chemical waste site Love Canal, which it sold in 1953, and led to a lengthy lawsuit several decades later.

The company was founded in 1903 as "The Development and Funding Company" by Elon Huntington Hooker, of Rochester, NY. Hooker created a company that used the Townsend cell to elecrolyse salt into chlorine and sodium hydroxide (NaOH), also known as "caustic soda" and "lye," in a chloralkali process. Elmer Sperry, founder of Sperry Electric, and Leo Baekeland, inventor of Bakelite and Velox photographic paper consulted for Hooker to improve the design of the cell.

The company was originally sited in Niagara Falls, NY because of the low cost electricity from the Niagara Falls power project (completed in 1895), the abundance of salt from nearby mines, and availability of water from the Niagara River. However, in 1929 Hooker built a new chloralkali plant in Tacoma Washington. Hooker also owned factories in Albany, NY.

Hooker Chemical Company was purchased by Occidental Petroleum Corporation in 1968.

Brand/Importer Information: InterMountain was founded in 1985 by Fred Brummet. They got started in the model railroad business by producing O-Scale model kits. They got started in the N Scale business almost a decade later when in 1994 they introduced the 40-23 reefer car in kit form. Later, in 1998, they started producing RTR (Ready-to-Run) models. By the early 2000s, InterMountain phased out kit production in favor of the RTR models.

The InterMountain Railway company is located at 1224 Boston Ave in Longmont, CO. They are a manufacturer of HO, N and Z scale model trains. They have produced kits as well as RTR (Ready-To-Run) models. Their N Scale products include locomotives as well as rolling stock. Their rolling stock lineup includes Boxcars, Hoppers, Tank Cars, Reefers, Gondolas, Stock Cars and Flatcars.

Their locomotive releases have primarily been diesel units, with the one major exception being their series of AC-12 Cab Forward steam locos. Their diesel lineup includes F3's, F7's, F9's, SD40's, SD45's and FT units. They are known for quality and detail. They also release their rolling stock in larger varieties of road numbers than most of the other manufacturers.
