Constant improvement in rail/wheel contact, increase in product life and reduced wear, plus minimised maintenance operations - these are the main aims of Vossloh Cogifer's R & D teams.

Complete laboratory tests
fatigue;
static;
artificial ageing;
stiffness measurements;
process validation (welding, bonding).

Rail measurements
displacement;
acceleration;
throw effort;
stress
laser geometry readings (frog/cradle, interlock).

Modelling and simulation
behaviour of components and sub-assemblies;
finite element calculations for strategic components.
