CogX - The Hard & Durable Rolled Steel for Railway Crossings and Switch Components

Overview

CogX is a pioneering solution in the realm of railway infrastructure, featuring hard and durable rolled steel specifically designed for applications such as tramway switch components, railway crossings, and expansion joint cradles. Engineered for high performance and tailored designs, CogX sets a new standard in the market.

Key Applications

  • Tramway: Half switch blocks, switch blades
  • Railway crossings
  • Expansion joint cradles

With thicknesses ranging from 60 to 200 mm, CogX is versatile enough to meet a variety of infrastructural needs.

Proven Reliability

CogX has been effectively installed in various locations, showcasing its dependability across different environments:

  • Sweden: Trafikverket
  • Great Britain: Tramway of Manchester
  • Belgium: Gent / Arcelor plant
  • Mauritania: SNIM
  • Netherlands: RET
  • Denmark: Metro of Copenhagen
  • Portugal: Expansion Joint

Since its introduction in 2017, in-track tests across numerous applications have demonstrated complete satisfaction with this innovative material.

Material Characteristics

  • Initial Hardness: 450 HB
  • Running Surface Hardness: Up to 550 HB
  • High Profile Stability & Creep Resistance
  • No Material Flow or Deformation
  • Allows Higher Transit Tonnage
  • Enhanced Wear and Impact Resistance
  • Excellent Weldability

CogX is specifically crafted for turnouts subjected to high traffic density, ensuring longevity and resilience.

 

Technical Advantages

Hardness increases from approximately 450 HB after machining, progressing to 550 HB due to the natural hammering effect from wheel passage.

Maintains necessary elasticity, making it suitable for impacted parts.

Wear resistance enables a lifespan of up to 300 million tons of passage, significantly outlasting equivalent designs.

Design Flexibility

CogX offers reduced production time and lower lifecycle costs:

  • No foundry patterns required
  • High flexibility in new design creation
  • Direct welding capability between the block and rail

Ideal for various geometries, CogX enables precise cutting and milling for new designs. Applications include:

  • Crossings, half switches, and switches for tramway applications
  • Crossings and points of crossings for conventional railways
  • Crossings for heavy haul
  • Crossings for metro applications
