Locomotion

Traction and drive gearing for locomotives and rail equipment built for high-mileage reliability.

Built for locomotion

Rail equipment depends on gearing that delivers high torque and long service life over enormous mileage. We manufacture traction gears, pinions, and drive components for locomotives and rail systems — hardened and finished for the reliability demanded by continuous rail operation.

Challenges we solve

  • High-torque traction gearing for continuous mileage
  • Precision pinions and drive gears for rail systems
  • Consistent case hardening for long fatigue life
  • Replacement gearing for legacy rolling stock
