Standards Development

Scope

This document supports rolling stock procurement and life cycle cost (LCC) assessments. It 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.The results obtained from this methodology can be directly compared to, or be representative of, the operation of a train. This document considers the energy consumed and regenerated by rolling stock and the determination methods covered are simulation and measurement.A framework is given 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 does not cover the comparison of energy consumption with other modes of transportation, or comparison between diesel and electric traction; only the energy consumption of rolling stock itself is covered.This standard, 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.
