UIC 519

Railway Wheelset Equivalent Conicity Determination

This test method specifies procedures for determining the equivalent conicity of railway wheelsets, a critical parameter governing vehicle stability and steering behavior on curves. Conicity describes the geometric relationship between wheel profiles and rail geometry, affecting how vehicles negotiate curves and respond to track irregularities. The measurement is essential for wheelset manufacturers, vehicle designers, and track maintenance specialists to ensure stable, safe operation and minimize wear and derailment risk. Accredited testing provides objective verification that wheelsets meet design specifications and regulatory requirements for dynamic safety.

What it measures

  • Wheel profile geometry and taper angles
  • Equivalent conicity value (λ)
  • Wheelset geometric parameters and deviation
  • Contact point position relative to wheel center
  • Stability characteristics and steering forces
