Friction modifier between wheel and rail

One of the solutions for contact problems between wheel and rail is to keep appropriate friction coefficient.
We provide the solution by supplying innovative friction control material,
which is developed based on advanced tribology theory and abundant practical results.

  • Liquid type friction modifier (Distribution bar)
  • Solid type friction modifier (On-board application)

Rail stress monitoring system

Rail especially continuous welded rail is laid with appropriate axial stress to prevent deficient phenomenon such as track buckling and rail breakage, even if rail stress varies by temperature change and sunlight in summer and winter. Continuous and accurate remote monitoring of rail temperature and stress is possible by rail stress monitor and the system.

  • Rail stress monitor (RSM)
  • System configuration diagram of measurement-communication-monitoring Railway Solution & System
