High Energy Efficiency - an overview ScienceDirect Topics

The high energy efficiency of railway transportation is made possible by the favourably low losses in the rolling contact between the hard surfaces of the wheel and rail, which meet only in a very small contact patch. However, several undesired phenomena may occur in this contact, see Fig. 1.1.High vertical contact forces, but also lateral and longitudinal forces, induce stresses that may ...
