prEN IEC 63593:2025

This document is applicable to rolling stock energy consumption specification and verification and establishes a methodology for the calculation of energy consumption which can be used to determine the total net energy consumed from a primary power source (e.g. at current collector or from the fuel tank), over a predefined service profile. It gives guidance to rolling stock procurement and life cycle cost (LCC) assessments.
This document specifies the methodology for simulation and measurement of energy consumed and regenerated by rolling stock. The results obtained from this methodology can be directly compared to, or be representative of, the operation of a train.
This document establishes a framework on the generation of common, comparable energy performance values for rolling stock which supports the benchmarking and improvement of the energy efficiency of rolling stock.
This document, as a whole or in part, applies to all railway vehicles except coal-powered vehicles, special purpose vehicles (e.g. shunting locomotives, vehicles for track construction and maintenance) and magnetically supported vehicles.
This document does not apply to the comparison of energy consumption with other modes of transportation, or comparison between diesel and electric traction; it applies only to the energy consumption of rolling stock itself.
