For over 100 years, Miner Enterprises, Inc. has supplied the railroad industry with quality manufactured and engineered railcar components. Founded in 1894, the W.H.Miner spring draft gears filled a special need during the railroads’ transition from wooden frames and the standardization of draft gear pockets, automatic couplers and braking systems from approximately 1885 to 1919. The key patents involved in this evolutionary period of our draft gears business is covered in a new publication “The Amazing Story of the Miner Spring Draft Rigging” brochure (approx. 20mb).

W.H. Miner Division has since grown to include draft gears, discharge gates and mechanisms, side bearings, and brake beams. The current company is a result of the 1968 purchase of W.H. Miner Company and Enterprise Railway Equipment. It has become one of the industry's most experienced gate manufacturers and also manufactures mechanisms for coal, ore, and ballast unloading. In 2000, Miner continued its expansion of high quality product offerings with the purchase of Buffalo Brake Beam, manufacturing the highest quality brake beams in the industry.

W.H. Miner is a major supplier of freight car components to the railroad industry. Our customer list comprises all Class I and Class II railroads worldwide, freight car builders, private-car companies, leasing companies, and contract freight car repair shops.
