Specification and verification of energy consumption for railway rolling stock

The main purpose of this standard is the support of rolling stock procurement, especially in light of life cycle cost (LCC) assessment.
This European Standard is applicable to the specification and verification of energy consumption of railway rolling stock. It establishes a criterion for the energy consumption of rolling stock to calculate the total net energy consumed, either at current collector or from the fuel tank, over a predefined service profile, in order to assure that the results are directly comparable or representative of the real operation of the train. For this purpose, this document takes into account the energy consumed and regenerated by the rolling stock.
This European Standard provides the framework that gives guidance on the generation of comparable energy performance values for trains and locomotives on a common basis and thereby supports benchmarking and improvement of the energy efficiency of rail vehicles.
This European Standard does not cover specification for comparison of energy consumption with other modes of transportation, or even for comparison between diesel and electric traction, covering only the energy consumption of the railway rolling stock itself.

Spezifikation und Überprüfung des Energieverbrauchs von Schienenfahrzeugen

Spécification et vérification de la consommation d’énergie pour le matériel roulant ferroviaire

L'objectif principal de la présente norme est l'appui à l'acquisition de matériel roulant, en particulier à la lumière d'une évaluation du coût du cycle de vie (CCV).
La présente Norme européenne est applicable à la spécification et à la vérification de la consommation d'énergie du matériel roulant ferroviaire. Elle établit pour la consommation d'énergie du matériel roulant un critère qui permet de calculer la consommation d'énergie totale nette, mesurée au niveau de l'appareil de captage de courant ou du réservoir de combustible, sur un profil de service prédéfini, afin de s'assurer que les résultats sont directement comparables ou représentatifs de l'exploitation réelle du train. Dans ce cadre, le présent document comptabilise l'énergie consommée et régénérée par le matériel roulant.
La présente Norme européenne fournit le cadre et des recommandations pour la production de valeurs de performance énergétique comparables pour les trains et les locomotives en se fondant sur une base commune, ce qui favorise l'analyse comparative et l'amélioration de l'efficacité énergétique des véhicules ferroviaires.
La présente Norme européenne n'est pas une spécification visant à comparer la consommation d'énergie entre différents modes de transport, ou à comparer la consommation d'énergie entre les systèmes de traction diesel et électrique. Elle s'intéresse uniquement à la consommation d'énergie du matériel roulant ferroviaire.

This document supersedes CLC/TS 50591:2013.

The main changes in this edition compared to CLC/TS 50591:2013 are the adoption of existing

CLC/TS 50591 enquiry comments, the harmonization with results from the European Lighthouse

Project Roll2Rail and the inclusion of an HVAC energy quantification method. Since separate methods

for traction and HVAC energy quantification are described, the document structure had to be revised.

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. CENELEC shall not be held responsible for identifying any or all such patent rights.

This document has been prepared under a mandate given to CENELEC by the European Commission

1 Scope

The purpose of this document is to support rolling stock procurement, especially life cycle cost (LCC)

assessment.

This document is applicable to the specification and verification of energy consumption of railway

rolling stock. It establishes a criterion for the energy consumption of rolling stock to calculate the total

net energy consumed, either at current collector or from the fuel tank, over a predefined service

profile, to ensure that the results are directly comparable or representative of the real operation of the

train. For this purpose, this document considers the energy consumed and regenerated by the rolling

stock. The determination methods covered are the simulation and the measurement.

This document provides the framework that gives guidance on the generation of comparable energy

performance values for trains and locomotives on a common basis and thereby supports

benchmarking and improvement of the energy efficiency of rail vehicles.

This document does not cover the comparison of energy consumption with other modes of

transportation, or even for comparison between diesel and electric traction, covering only the energy

consumption of the railway rolling stock itself.

4 General

Energy is an integral quantity. This means that the cumulated energy is the decisive factor. Realistic

train operation always takes place under the constraints of infrastructure and operational

requirements.
The following train modes are used in this standard:
— In-service with commercial operation mode:

This mode covers the normal operation of a train, including several passenger load cases or a

locomotive hauling a consist of freight wagons. The train is moving or is stationary and the HVAC

system is running in its normal operation mode.
— In-service without commercial operation mode:

In this mode a passenger train is stationary, the HVAC system is in operation as for commercial

operation but without passengers in the train. This situation occurs frequently, for example when

the train is waiting between two commercial runs.
— Parking mode:

A train is in parking mode when it is stationary in depots, with the power supply active, without

staff or passengers being on board. Usually, the HVAC system runs with reduced settings for

temperature and airflow.

Other train modes such as empty carriage stock movements are not considered in this standard as

they do not contribute significantly to the annual energy consumption.

In this standard the preconditioning (pre-heating or pre-cooling) and cleaning are not considered

separately. The corresponding hours shall be counted in the in-service without commercial operation

mode.
---------------------- Page: 11 ----------------------
SIST EN 50591:2020
EN 50591:2019

The train is switched OFF for remaining time of each day, therefore without any energy consumption.

To keep different characteristics, requirements and procedures manageable, the energy consumption

of the whole train is subdivided into the following three different energy categories, which are handled

separately:

1) Traction and Auxiliaries (in-service with commercial operation mode, without HVAC);

2) Traction and Auxiliaries (in-service without commercial operation mode and in parking mode,

without HVAC);
3) HVAC.

This document incorporates infrastructure and operational conditions into “service profiles” for the

train. The service profile for traction and auxiliaries is assessed via train runs along a line for in service

with commercial operation and stationary at the depot for in service without commercial operation.

HVAC is assessed via an operational point matrix for different operational modes.

The energy consumption over such service profiles shall be used as an input when assessing LCC.

This requires a well-defined and harmonized methodology for specification and verification of the

energy consumption. The selected approach has two steps:

a) simulation of the energy consumption of the train for the three energy categories mentioned

above;
b) verification of the simulation by undertaking measurements.

It is important to note that two different types of service profiles for traction and auxiliaries may be

chosen:

4) user-defined service profiles based on data from a real railway line, normally one or several lines

of the railway network where the train will be operated;
5) standard service profiles, for the following categories:
— suburban (passenger service);
— regional (passenger service);
— intercity (passenger service);
— high speed (passenger service);
— freight mainline serv
