EN 15663:2017

Railway Vehicle Reference Masses Definition

This standard defines the methodology for calculating and specifying reference masses for railway vehicles, including tare mass, maximum operational mass, and mass distribution. Reference masses are essential parameters used in structural design calculations, brake sizing, dynamics simulations, and operational planning. Accredited mass determination testing ensures accurate vehicle specifications that are critical for safety calculations, compatibility with infrastructure, and compliance with axle load regulations across the European rail network.

What it measures

  • Tare mass (unladen vehicle weight)
  • Maximum operational mass (fully loaded weight)
  • Centre of gravity location and distribution
  • Axle load distribution and balance
  • Mass calculation methodologies and assumptions
