Million Sold | Over 2 Million Miles of Tested Service

GENEVA, IL USA – Today, Miner Enterprises, Inc. celebrates Miner's TF-880 draft gear – the only friction elastomer gear to surpass 30+ years of experience and more than 2 million miles in service.
This "Miner Milestone" product continues to deliver astonishing measures of value to railcar owners, fleet operators, leasing companies and railroads—not to mention the shippers who hire them to move precious cargo across the globe.
Its light weight and high performance design maximizes railcar protection while minimizing life cycle costs. This double benefit is achieved via the friction clutch and how it amplifies the energy absorption of the TF-880's patented TecsPak® spring package.
Engineered by Miner, TecsPak® elastomer spring packages provide superior energy management and a consistently robust spring package, compared to steel springs, for applications spanning the transportation industry.
More than 1.7 million TF-880 draft gears have been sold since it first received A.A.R certification almost four decades ago. Rigorous field tests over the years continue to confirm that these energy management workhorses still perform within specs after 2 million miles of service.
Now that's a Miner Milestone.
