Curve Wear
High lateral force in tight curves accelerates wheel flange and gauge-face damage.
Rail Business Unit
NATCO-RAIL Wear, Noise, and Friction Control
Integrated wayside lubricators, top-of-rail friction modifiers, and intelligent monitoring for metro and railway networks.
Operational Challenge
Where Rail Assets Lose Value
NATCO rail programs target the highest-cost failure points first: curve wear, friction instability, and noise complaints in dense transit corridors.
Squeal Noise
Stick-slip behavior at wheel-rail contact generates high-frequency noise in urban corridors.
Creep & Slip
Loss of healthy rolling friction increases energy use, track defects, and braking variability.
