Exhibitor profile

Perfecting Railcar Performance

Miner Enterprises, Inc. is a leading designer, manufacturer, and supplier of wagon components to railroads, locomotive and freight wagon builders, private wagon companies, and repair shops in 56 countries around the world.

Since 1894, Miner has focused on improving the performance and value of its products and the freight cars that use them through frequent testing, in-depth service analysis and industry-related experience spanning 120 years.

Miner’s TecsPak® buffer springs and drawgears are part of a product line that includes high capacity draft gears, TecsPak constant contact side bearings, brake beams, and a variety of discharge devices. These TecsPak buffer springs and drawgears have been proven in rail service throughout Europe on locomotives, freight wagons, and passenger coaches since 1979 and they comply with EN Specifications.

The TecsPak polymer material developed by Miner is lightweight yet can withstand extreme loads. It absorbs far more energy per unit of weight and volume than its closest competitor. Springs made of TecsPak last up to 20 times longer than urethane, 10 times longer than rubber, and 5 times longer than steel springs. TecsPak buffer springs and drawgears are maintenance free, never need adjustment, operate in temperatures ranging from -40° C to +50° C, and are available with ultraviolet protection.

Miner’s experienced staff of engineers and technicians is knowledgeable, innovative, and committed to excellence. They work closely with sales and marketing to provide quality products that meet or exceed customer needs and respond to the changing conditions of the transportation industry. Supporting engineering and manufacturing is a research and development department recognized for excellence throughout the railroad and transportation industries.
