Division 2.2.4 Support and guide the train on the track

The different needs of this subsystem are defined by standards for the wheels that comprise the interface with the rail in the infrastructure subsystem.

The contact geometry is such that the stability of the train with all its equipment in good working order is ensured at the highest operating speed specified for the trainset. This aspect allows the interface with the many parameters within the infrastructure subsystem such as the track gauge, cant deficiency and equivalent conicity, to be defined.
