(notified under document C(2011) 658)

(Text with EEA relevance)

(2011/229/EU)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Directive 2008/57/EC of the European Parliament and of the Council of 17 June 2008 on the interoperability of the rail system within the Community (1), and in particular Article 6(1) thereof,

Having regard to the recommendation of the European Railway Agency (No ERA/REC/02-2010/INT) of 30 March 2010,

Whereas:

| (1) | Article 12 of Regulation (EC) No 881/2004 of the European Parliament and of the Council (2) requires that the European Rail Agency (hereinafter ‘the Agency’) shall ensure that the technical specifications for interoperability (hereinafter referred to as ‘TSIs’) are adapted to technical progress and market trends and to the social requirements and propose to the Commission the amendments to the TSIs which it considers necessary. |
| --- | --- |

(1)

Article 12 of Regulation (EC) No 881/2004 of the European Parliament and of the Council (2) requires that the European Rail Agency (hereinafter ‘the Agency’) shall ensure that the technical specifications for interoperability (hereinafter referred to as ‘TSIs’) are adapted to technical progress and market trends and to the social requirements and propose to the Commission the amendments to the TSIs which it considers necessary.

| (2) | By Decision C(2007)3371 of 13 July 2007, the Commission gave a framework mandate to the Agency to perform certain activities under Council Directive 96/48/EC of 23 July 1996 on the interoperability of the trans-European high-speed rail system (3) and Directive 2001/16/EC of the European Parliament and of the Council of 19 March 2001 on the interoperability of the trans-European conventional rail system (4). Under the terms of this framework mandate, the Agency was requested to perform the limited revision of the conventional rail TSI on Rolling stock – Noise (hereinafter ‘TSI Noise’), adopted by Commission Decision 2006/66/EC (5). |
| --- | --- |

(2)

By Decision C(2007)3371 of 13 July 2007, the Commission gave a framework mandate to the Agency to perform certain activities under Council Directive 96/48/EC of 23 July 1996 on the interoperability of the trans-European high-speed rail system (3) and Directive 2001/16/EC of the European Parliament and of the Council of 19 March 2001 on the interoperability of the trans-European conventional rail system (4). Under the terms of this framework mandate, the Agency was requested to perform the limited revision of the conventional rail TSI on Rolling stock – Noise (hereinafter ‘TSI Noise’), adopted by Commission Decision 2006/66/EC (5).

| (3) | A reference track whose use is mandatory under TSI Noise is not available in every Member State, and the Member States cannot be obliged to create one. This has prevented the development of a level playing field for all actors in the European Union and has created the financial burden which is higher than foreseen in the original Decision. Numerous problems regarding the availability of reference track, the test methods and the test costs have been signalled to the Commission and to the Agency. |

(3)

A reference track whose use is mandatory under TSI Noise is not available in every Member State, and the Member States cannot be obliged to create one. This has prevented the development of a level playing field for all actors in the European Union and has created the financial burden which is higher than foreseen in the original Decision. Numerous problems regarding the availability of reference track, the test methods and the test costs have been signalled to the Commission and to the Agency.

| (4) | With the present Decision the Commission intends to clarify responsibilities with regard to the reference track, allow testing on non-reference track while assuring a proper collection and recording of comparable data for a future TSI revision, reduce the burden of proof compliance for small batches of vehicles and include the latest developments with regard to ISO EN 3095 standard. |

| (5) | The noise limits and the scope will remain unchanged. This Decision therefore constitutes only a limited revision of TSI Noise and does not compromise a full revision of TSI Noise as provided in Section 7 of the TSI. |
| --- | --- |

(5)

The noise limits and the scope will remain unchanged. This Decision therefore constitutes only a limited revision of TSI Noise and does not compromise a full revision of TSI Noise as provided in Section 7 of the TSI.

4.1.   Introduction

The trans-European conventional rail system, to which Directive 2008/57/EC applies and of which the rolling stock subsystem is a part, is an integrated system whose consistency shall be verified. This consistency shall be checked in particular with regard to the specifications of the subsystem, its interfaces in relation to the system into which it is integrated, as well as the operating and maintenance rules.

Taking account of all the applicable essential requirements, the rolling stock subsystem regarding Noise emitted by rolling stock is described in this section.

This TSI is applicable to new vehicles, and renewed or upgraded rolling stock if required by the provisions of Section 7.

Appendix G provides general information and definitions related to noise testing. When not described in this TSI the relevant EN standards shall be used with regards to terms, definitions, instrumentation and calibration, quality of the measurements, test report requirements and other general information related to the noise testing.

4.2.   Functional and technical specifications of the subsystem

In the light of the essential requirements listed in Section 3, the functional and technical specifications of the rolling stock subsystem regarding Noise emitted by rolling stock shall be as follows:

| (a) | stationary noise (basic parameters in points 4.2.1.2 and 4.2.2.2), |
| --- | --- |

(a)

stationary noise (basic parameters in points 4.2.1.2 and 4.2.2.2),

| (b) | starting noise (basic parameter in point 4.2.2.3), |
| --- | --- |

(b)

| (d) | interior noise of locomotives, multiple units and driving trailers (basic parameter in point 4.2.3). |
| --- | --- |

(d)

interior noise of locomotives, multiple units and driving trailers (basic parameter in point 4.2.3).

4.2.1.   Noise emitted by freight wagons

Noise emitted by freight wagons subdivides into pass-by noise and stationary noise.

The pass-by noise of a freight wagon is highly influenced by its rolling noise (noise of the wheel/rail contact) which is a function of speed.

The rolling noise itself is caused by the combined wheel and rail acoustic roughness and by the dynamic behaviour of the track and wheel-set.

The parameter set for the characterisation of pass-by noise comprises:

| (a) | sound pressure level, according to a defined measuring method. |
| --- | --- |

(a)

sound pressure level, according to a defined measuring method.

| (b) | microphone position, |
| --- | --- |

microphone position,

| (c) | speed of the wagon, |
| --- | --- |

(c)

speed of the wagon,

| (d) | track conditions (e.g. rail acoustic roughness, vertical and lateral track decay rates.) |
| --- | --- |

(d)

track conditions (e.g. rail acoustic roughness, vertical and lateral track decay rates.)

Stationary noise of a freight wagon will only be of relevance if the wagon is equipped with auxiliary devices like engines, generators, cooling systems.

The parameters set for the characterisation of stationary noise comprise:

| (a) | sound pressure level, according to a defined measuring method and microphone position, |
| --- | --- |

(a)

The indicator for pass-by noise is the A-weighted equivalent continuous sound pressure level LpAeq, Tp measured over the pass-by time at a distance of 7,5 m from the centre of the track, 1,2 m above top of rail.

Measurements shall be made in accordance with Appendix E.

The measured pass-by noise levels shall comply with the values as set out in table 1 when measured on track complying with Appendix A. It is permitted to carry out the test on track that does not comply with Appendix A and if the noise levels do not exceed the values shown in table 1, there is a presumption of conformity to this requirement.

The following conditions of the track on which the pass-by noise measurement is performed shall be measured and recorded:

| (a) | the vertical and lateral track decay rate in accordance with EN 15461 |
| --- | --- |

(a)

the vertical and lateral track decay rate in accordance with EN 15461

| (b) | the track acoustic roughness in accordance with EN 15610. |
| --- | --- |

(b)

the track acoustic roughness in accordance with EN 15610.

If the track on which the measurements were performed did meet the reference conditions as set out in Appendix A, or if the acceptance criterion of Appendix B is met, the measured values shall be marked ‘comparable’. Otherwise the measured values shall be marked ‘non-comparable’.

An entry shall be recorded in the technical file and in the ERATV if the measured values are ‘comparable’ or ‘non-comparable’. Measured values of noise, as well as corresponding track quality shall be saved in the technical file for later evaluation of correspondence between vehicle and track noise for both comparable and non-comparable data.

The measured acoustic rail roughness shall remain valid during a period starting 3 months before the measurement and ending 3 months after the measurement, provided that during this period no track maintenance has been performed which influences the rail acoustic roughness.

The measured track decay rates shall remain valid during a period starting 1 year before the measurement and ending 1 year after the measurement, provided that during this period no track maintenance has been performed which influences the track decay rates.

If beyond the limits of these periods, the same stretch of track is used again for pass-by noise measurements, it is necessary to measure the acoustic roughness or decay rates again. Proof shall be provided in the technical file that the track data related to the type’s pass-by noise measurement were valid during the day(s) of testing, e.g. by providing the date of last maintenance having an impact on noise.

The value to be compared with the limits (see Table 1) is the maximum of the measured value at 80 km/h and the measured value taken at maximum speed but referred to 80 km/h by the equation LpAeq,Tp (80 km/h) = LpAeq,Tp(v)-30*log (v/80 km/h).

4.2.2.   Noise emitted by locomotives, multiple units, coaches and OTMs

4.2.2.1.   Introduction

In line with point 2.1.5, OTMs shall be assessed against the requirements for locomotives. Where applicable, the category of locomotive (electric, diesel) of which the requirements shall be used, shall correspond to the traction equipment installed in the OTM. If the OTM is diesel engine powered, it shall correspond to diesel locomotives with P >/= 2 000 kW at the engine output shaft. If the OTM is not equipped with traction equipment, measurement conditions of coach/wagon should be used (no starting noise test) but the limit values for locomotives shall be applied.

Noise emitted by locomotives, multiple units and coaches subdivides into stationary noise, starting noise, and pass-by noise. The noise within a driver’s cab is a parameter for units equipped with a driver’s cab.

The stationary noise is highly influenced by auxiliaries, such as cooling systems, air conditioning and compressors.

Starting noise is a combination of contributions from traction components such as diesel engines, cooling fans and auxiliaries.

Pass-by noise is highly influenced by the rolling noise, linked to the wheel/rail interaction, which is a function of speed.

The rolling noise itself is caused by the combined wheel and rail roughness and by the dynamic behaviour of the track and wheelset.

At lower speeds the noise of auxiliaries and traction equipment is also significant.

The emitted level of noise is characterised by:

| (a) | Sound pressure level, according to a defined measuring method, |
| --- | --- |

4.2.2.3.   Limits for starting noise

The limits for starting noise are defined at a distance of 7,5 m from the centre of the track, 1,2 m above top of rail.

Measurements shall be made in accordance with Appendix D.

For OTMs the starting procedure shall be performed without additional trailer loads. The indicator for the sound level is LpAFmax. The limiting values for the starting noise of the vehicles under the conditions stated are given in Table 4.

4.2.2.4.   Limits for pass-by noise

The limits for pass-by noise are defined at a distance of 7,5 m from the centre of the track, 1,2 m above top of rail for a vehicle speed of 80 km/h. The indicator for the A weighted equivalent continuous sound level is LpAeq,Tp.

Measurements shall be made in accordance with Appendix E.

The Measured pass-by noise levels shall comply with the values as set out in table 5 when measured on track complying with Appendix A. It is permitted to carry out the test on track that does not comply with Appendix A and if the noise levels do not exceed the values shown in table 5, there is a presumption of conformity to this requirement.

The following conditions of the track on which the pass-by noise measurement is performed shall be measured and recorded:

| (a) | the vertical and lateral track decay rate in accordance with EN 15461 |
| --- | --- |

(a)

the vertical and lateral track decay rate in accordance with EN 15461

| (b) | the track acoustic roughness in accordance with EN 15610. |
| --- | --- |

(b)

the track acoustic roughness in accordance with EN 15610.

If the track on which the measurements were performed did meet the reference conditions as set out in Appendix A, or if the acceptance criterion of Appendix B is met, the measured values shall be marked ‘comparable’. Otherwise the measured values shall be marked ‘non-comparable’.

An entry shall be recorded in the technical file and in the ERATV if the measured values are ‘comparable’ or ‘non-comparable’. Measured values of noise as well as corresponding track quality shall always be saved in the technical file for later evaluation of correspondence between vehicle and track noise for both comparable and non-comparable data.

The measured acoustic rail roughness shall remain valid during a period starting 3 months before the measurement and ending 3 months after the measurement, provided that during this period no track maintenance has been performed which influences the rail acoustic roughness.

The measured track decay rates shall remain valid during a period starting 1 year before the measurement and ending 1 year after the measurement, provided that during this period no track maintenance has been performed which influences the track decay rates.

If beyond the limits of these periods, the same stretch of track is used again for pass-by noise measurements, it is necessary to measure the acoustic roughness or decay rates again. Proof shall be provided in the technical file that the track data related to the type’s pass-by noise measurement were valid during the day(s) of testing, e.g. by providing the date of last maintenance having an impact on noise.

If the maximum operational speed of the unit is lower than 80 km/h, the unit shall be tested at this maximum speed, the pass-by noise limits for 80 km/h apply without any correction. Otherwise the pass-by noise of a unit shall be measured at 80 km/h and at v (where v = 190 km/h, or the maximum operational speed for which the unit is designed, if this maximum speed is lower than 190 km/h). The value to be compared with the limits (see Table 5) is the greater of the measured value at 80 km/h and the measured value taken at maximum speed but normalised to 80 km/h by the equation.

LpAeq,Tp(80 km/h) = LpAeq,Tp(v)-30*log (v/80 km/h).

The limiting values for the noise emission of electric and diesel locomotives, EMUs, DMUs and coaches under the conditions stated above are given in Table 5. For OTMs the measuring procedure shall be performed without additional trailer loads.

4.2.3.   Interior noise of locomotives, multiple units and coaches fitted with a cab

As addressed in point 2.1.5, OTMs shall be assessed against the requirements for locomotives.

The interior noise level of passenger vehicles is not considered to be a basic parameter. However, the noise level within the driver’s cab is an important issue. Noise levels in the cab must be kept as low as possible, by limiting the noise at the source and by appropriate additional measures (acoustic insulation, sound absorption). The limiting values are defined in Table 6. For OTMs the measuring procedure shall be performed without additional trailer loads.

Measurements shall be made in accordance with Appendix F.

6.2.3.   Verification methods specific to noise aspects of rolling stock

6.2.3.1.   Introduction

Notwithstanding the exemptions as described in this section, by default all new types need to be assessed in compliance with the requirements specified in Section 4 of this TSI. Instead of the test procedures as set out in Section 4 of this TSI, it may be permitted to substitute some or all of the tests by a simplified evaluation method. The eligibility criteria and requirements associated to the simplified evaluation method are set out in this section.

The simplified evaluation method consists of acoustically comparing the type under assessment to an existing type with documented noise characteristics compliant with the noise TSI; the latter is further referred to as the reference type.

It is permitted to substitute noise testing by a simplified evaluation, if the type under assessment is comparable to a reference type which has been tested in compliance with one of the following:

| (a) | Section 4 of this TSI and for which the pass-by noise results are marked ‘comparable’, or |
| --- | --- |

(a)

Section 4 of this TSI and for which the pass-by noise results are marked ‘comparable’, or

| (b) | in compliance with Section 4 of the TSI CR ‘rolling stock— noise’ adopted by Decision 2006/66/EC. |
| --- | --- |

(b)

in compliance with Section 4 of the TSI CR ‘rolling stock— noise’ adopted by Decision 2006/66/EC.

The following units are eligible for a simplified evaluation:

| (a) | Different formations of multiple units, |
| --- | --- |

| (c) | New units which are largely based on an existing design (same vehicle family). |
| --- | --- |

(c)

New units which are largely based on an existing design (same vehicle family).

For the units under assessment for simplified evaluation, the proof of conformity shall include a detailed description of the noise relevant changes compared to the reference type. From this description, a simplified evaluation (see points 6.2.3.2 and 6.2.3.3) shall be performed to identify the differences in terms of expected noise emission, of the noise cases specified in point 4.2 between the reference unit and the unit under assessment.

The simplified evaluation may be used on a unit for each of the individual noise cases autonomously: stationary noise, starting noise, cab-noise and pass-by noise.

6.2.3.2.   Simplified evaluation for locomotives, multiple units, coaches and OTMs

The simplified evaluation shall prove that the unit under assessment complies with the applicable noise levels as set out in this TSI, for those noise cases for which the simplified evaluation is used.

The simplified evaluation on a unit shall consist of providing evidence to show that the acoustically relevant systems and characteristics are either identical to those of the reference type, or such that they will not result in higher noise emission of the unit under assessment. The simplified evaluation can either be a calculation, or simplified measurement (e.g. sound power of noise sources), or a combination of both. Noise relevant systems which differ from the reference type shall be identified in the technical file.

6.2.3.3.   Simplified evaluation for freight wagons

For upgraded or renewed wagons, also see point 7.6.1. In case additional conformity assessment is needed and where table 7 is complied with, the simplified evaluation method is permitted to be used for upgraded or renewed freight wagons.

For new wagons: in cases where table 7 is complied with, the simplified evaluation method is permitted to be used for freight wagons.

In this case, the applicant may issue its EC declaration without further evaluation. This is only permitted if there are no derogations relating to noise aspects.

7.   IMPLEMENTATION

7.1.   General

The implementation of the TSIs must take into consideration the overall migration of the conventional rail network towards full interoperability.

In order to support this migration, the TSIs allow for staged, gradual application and coordinated implementation with other TSIs.

7.2.   TSI Revision

In conformity with Article 6(2) of Directive 2008/57/EC, the Agency shall be responsible for preparing the review and updating of TSIs and making appropriate recommendations to the Commission in order to take account of developments in technology or social requirements. In addition, the progressive adoption and revision of other TSIs may also impact this TSI.

the inclusion into the TSI of a monitoring scheme for wheel defects. Wheel defects have an impact on noise emission.

7.3.   A two step approach

It is recommended that in the case of new rolling stock to be ordered after 23 June 2016, or authorised to be placed into service after 23 June 2018, points 4.2.1.1 and 4.2.2.4 of this TSI are applied with a reduction of 5 dB except for DMUs and EMUs. For both latter cases the reduction is 2 dB. This recommendation will serve only as a basis for revising points 4.2.1.1 and 4.2.2.4 in the context of the TSI revision process mentioned in point 7.2.

7.4.   Retrofitting programme for noise reduction

Given the long life-cycle of railway vehicles it is also necessary to take measures on the existing fleet of rolling stock, with priority for freight wagons, to foster a noticeable reduction of the perceived noise level within a reasonable time period. The Commission will take initiatives to discuss options for retrofitting of freight wagons with the relevant stakeholders to achieve a general agreement with the industry.

7.5.   Application of this TSI to new rolling stock

The specifications provided by this TSI apply to all new rolling stock within the scope of this TSI.

7.5.1.   Starting noise

The starting noise limits may be raised by 2 dB for all DMUs, with an engine power greater than 500 kW/engine, authorised to be placed into service by 23 June 2011 at the latest.

7.5.2.   Exceptions for national, bilateral, multilateral or multinational agreements

7.5.2.1.   Existing agreements

Where notified agreements contain requirements related to noise, these agreements remain permitted until the necessary measures are taken including EU level agreements related to this TSI with the Russian Federation and all the other CIS countries having a border with the EU.

7.5.2.2.   Future agreements or modification of existing agreements

Any future agreement or modification of existing agreements shall take into account EU legislation and, in particular, this TSI. Member States shall notify the Commission with such agreements/modifications.

7.6.   Application of this TSI to existing rolling stock

7.6.1.   Renewal or upgrading of existing freight wagons

In the case of renewal or upgrading of freight wagons, the Member State concerned has to decide, in accordance with Article 20 of Directive 2008/57/EC, if a new authorisation for placing into service is needed. If the performance of the brake system of this wagon is changed by the renewal or upgrading and if a new authorisation of placing into service is needed, the requirement is that the pass-by level of this wagon shall comply with the relevant level indicated in Table 1 of point 4.2.1.1.

If a wagon during renewal or upgrading is being equipped (or is already equipped) with composite blocks and without adding additional noise sources to the wagon, it shall be assumed without testing that the values of point 4.2.1.1 are fulfilled.

An upgrading for noise emission reduction only is not mandatory, but if upgrading is done for another reason it shall be demonstrated that renewal or upgrading does either not increase pass-by noise levels, or when increased remain within the limits which are specified in this TSI.

For stationary noise, it shall be demonstrated that the stationary noise levels do either not increase, or when increased remain within the limits which are specified in this TSI.

As an alternative to full vehicle measurement, the demonstration of compliance of a unit is permitted to be performed by an evaluation under the conditions as defined in point 6.2.3 of this TSI. In this case the unit before upgrade shall act as the reference unit.

7.6.2.   Renewal or upgrading of locomotives, multiple units, coaches and OTMs

It shall be demonstrated that the noise levels of renewed or upgraded units are either not increased, or when increased remain within the limits which are specified in this TSI.

The demonstration of compliance of a unit can, as an alternative to full vehicle measurement, also be done by an evaluation under the conditions as defined in point 6.2.3 of this TSI. In this case the unit before upgrade acts as the reference unit.

7.7.   Specific cases

7.7.1.   Introduction

The following special provisions shall apply in the specific cases referred to in this point.

Specific cases belong to two categories: the provisions apply either permanently (case P), or temporarily (case T). In temporary cases, it is recommended that the Member States concerned should conform with the relevant subsystem either by 2010 (case T1), an objective set out in Decision No 1692/96/EC of the European Parliament and of the Council of 23 July 1996 on Community guidelines for the development of the trans-European transport network (3), or by 2020 (case T2).

7.7.2.2.   Finland

Category P –   Permanent

The application of national technical rules instead of the requirements in this TSI is permitted for third countries’ rolling stock to be used on the Finnish 1524 network in traffic between Finland and third countries 1520 network.

Category T1 —   temporary

In the territory of Finland, the limits for stationary noise in point 4.2.1.2 shall not be applied to wagons equipped with a diesel aggregate for electrical power supply higher than 100 kW when the aggregate is used. In this case the stationary noise limit may be raised by 7 dB due to the temperature range down to — 40 °C together with freezing and icy conditions.

7.7.2.3.   Limits for starting noise, ‘strictly for use on the UK and Ireland networks only’

7.7.2.4.   Limits for pass-by noise for freight wagons, in Finland, Estonia, Latvia and Lithuania

Category T1 —   temporary

The noise emission limits for freight wagons are not valid for Finland, Estonia, Latvia and Lithuania. The reason for this is the safety aspects under Nordic winter conditions. This specific case is valid until the functional specification and assessment method for composite brake blocks are incorporated in the revised version of the WAG TSI.

That does not preclude freight wagons from other Member States from operating in Nordic and Baltic States.

7.7.2.5.   Specific case for Greece

Category T1 —   temporary: rolling stock for track gauge 1 000 mm or less

For the existing isolated 1 000 mm gauge, national rules shall apply.

7.7.2.6.   Specific case for Estonia, Latvia and Lithuania

Category T1 —   temporary

The noise emission limits for all rolling stock (locomotives, coaches, EMUs and DMUs) are not valid for Estonia, Latvia and Lithuania until the revision of this TSI. In the meantime, measurement campaigns will be carried out in these States; the revision of this TSI shall take into account the results of these campaigns.

APPENDIX B

SMALL DEVIATION CALCULATION METHOD

Method to assess acceptable small deviations from rail roughness requirements

B1.   Principle

The ‘small deviations’ method aims at introducing some flexibility in the conformity assessment of a test track section towards a limit curve of acoustic rail roughness within the frame of constant speed tests. Both the limit curve and the measured acoustic rail roughness spectra are assumed to be one-third octave band wavelength spectra.

Deviations to the track decay rates are not acceptable under the Small deviation calculation method.

The method relies on a calculation of a correction to the measured level based on the effect of any exceeding of a specified spectrum of acoustic rail roughness. The difference between the corrected pass-by noise level and the measured one is then compared to an acceptance criterion.

If the criterion is fulfilled, the acoustic impact of the rail roughness deviations is deemed ‘small’ and the measured pass-by noise level is considered to be comparable.

This method is train speed dependent.

B2.   Data Processing

B2.1.   Generate a ‘just compliant’ corrected spectrum from the measured acoustic rail roughness wavelength spectrum (step 1)

The measured rail acoustic roughness spectra shall be energetically averaged. A corrected spectrum shall be derived from the measured acoustic rail roughness wavelength spectrum and from the limit spectrum according to the following formula:

Formula

Where:

Formula


  is the one-third octave band wavelength spectrum of the measured acoustic rail roughness;

Formula


  is the one-third octave band wavelength limit spectrum;

Formula


  is the one-third octave band wavelength spectrum of the corrected acoustic rail roughness;

NOTE 1 The corrected acoustic rail roughness spectrum is equivalent to the measured one except in the wavelength bands where the measured spectrum exceeds the limits.

NOTE 2 The corrected acoustic rail roughness spectrum complies with the limit spectrum

B2.2.   Quantify the deviations in the rail roughness frequency spectrum (step 2)

Transform the one-third octave band wavelength spectra (corrected and measured acoustic rail roughnesses) into the frequency domain to synthesize one-third octave band frequency spectra compliant with EN 61260. This shall be carried out in two stages:

| (a) | First derive frequencies from wavelengths using the formula f = v/λ where λ is the wavelength and f is the corresponding frequency at train speed v. This leads to a non-normalized one-third octave frequency roughness spectrum. |
| --- | --- |

(a)

First derive frequencies from wavelengths using the formula f = v/λ where λ is the wavelength and f is the corresponding frequency at train speed v. This leads to a non-normalized one-third octave frequency roughness spectrum.

| (b) | Then distribute the energy in each frequency band over the normalized ones according to the algorithm supplied in annex C of EN15610 |
| --- | --- |

(b)

Then distribute the energy in each frequency band over the normalized ones according to the algorithm supplied in annex C of EN15610

The impact of the deviations on the acoustic rail roughness frequency spectrum is then quantified through a correcting spectrum which is calculated as follows:

Formula

Where:

Formula


  is the one-third octave frequency spectrum of the measured rail acoustic roughness;

Formula


  is the one-third octave frequency spectrum of the corrected rail acoustic roughness;

Formula


  is the one-third octave frequency correcting spectrum.

B.2.3.   Calculate a revised noise spectrum (step 3)

A revised noise spectrum shall be calculated from the measured noise level and the correcting roughness spectrum according to the following formula:

Formula

The revised noise spectrum is derived from a simplified process. This procedure shall not be used as a prediction method to correct noise levels.

NOTE Since it has been assumed, in the method of calculation, that the rail roughness exceeding directly applies to the total noise, the revised noise spectrum is the minimum that might have been measured with the just compliant roughness spectrum.

An upper bound of the noise impact of the rail roughness deviations shall then be derived from the measured and revised noise spectra by:

Formula

where
  Formula
  stands for the dB sum of all the one-third octave frequency bands i.

B3.   Acceptance criterion

The track shall be considered to be compliant regarding the acoustic rail roughness spectrum if the noise impact ΔLpAeq,Tp
  calculated according to step 3 is less than or equal to 1 dB.

This compliance shall be examined for one pass-by at each speed.

  T = 20s of background noise over all microphone positions shall be at least 10 dB below the LpAeq,Tp
  obtained when measuring the noise from the unit in the presence of background noise. For frequency analysis (only necessary in case the small deviation process is used) this difference shall be at least 10 dB in each frequency band of interest.

E2.   Track conditions

E2.1.   General

The track on which the measurements are performed shall have a consistent superstructure over a minimum length of twice the microphone distance to either side. This includes geometry of the line, track quality, rail roughness and track decay rates as described in this TSI.

E2.2.   Geometry of the line

The radius of curvature r of the track shall be:

r ≥ 1 000 m for tests at train speed v ≤ 70 km/h;

r ≥ 3 000 m for tests at train speed 70 < v ≤ 120 km/h;

r ≥ 5 000 m for tests at train speeds v > 120 km/h.

Where powered units are tested, the level gradient at the track shall be 5:1 000 at the most.

E2.3.   Track superstructure

The standard superstructure for the constant speed test is a track with ballast bed and wooden or reinforced concrete sleepers without any type of rail or track shielding (use of rail dampers is accepted to comply with track decay rate limits in this TSI).

There shall be no ice, frost, or other frozen water products on the test track. The temperature during measurements is permitted to be below zero degrees Celsius.

The track at the measuring section shall be laid without rail joints (welded rail) and be free of visible surface defects such as rail burns or pits and spikes caused by the compression of external material between wheel and rail: no audible impact noise due to welds or loose sleepers shall be present.

E3.   Vehicle conditions

E3.1.   General

Air management systems, including grilles, filters and fans, shall be clear of any obstruction.

During the measurements, the doors and windows of the unit shall be kept closed.

E3.2.   Loading

The normal operating conditions for stationary noise measurements apply, as defined in annex C of this TSI. Additionally, for fixed formation units, a minimum tractive effort to maintain a constant speed shall be applied during the pass-by noise measurement. To ensure a steady operating condition, it might be required to operate the unit already a certain time in advance in this operating condition.

Except for locomotives, during the pass-by noise measurements, units shall not be physically loaded beyond what is specified above, e.g. no goods shall be loaded to wagons and no passengers shall be present in passenger units.

If the unit being tested is a locomotive, the hauled load shall be at least two-thirds of the maximum permissible value. For the purposes of this standard, it is permissible to use the maximum tractive effort that can be generated at maximum speed as a proxy for maximum permissible hauled load (see Figure 5). Where appropriate meters and displays are available within the cab of the locomotive under test, the required testing condition may be ensured by operating the locomotive with an indicated tractive effort of at least two-thirds of the maximum available tractive effort. This condition is permitted to be ensured by including an instrumented brake vehicle within the hauled set of vehicles, thus allowing the tractive effort to be controlled precisely during the test period by brake application.

The test report shall describe the state of the traction equipments during the test.

E3.3.   Wheel tread conditioning

The unit shall be in its normal operating conditions and, for test with constant speed, its wheels shall have run in normal traffic at least 1 000 km on track with normal traffic. The wheel treads shall be as free as possible from irregularities, such as flats.

For units with tread brakes or scrubber (tread cleaning brakes) the block/tread pair shall be in a run-in condition where block and tread have bedded in sufficiently. Before starting the pass by measurements (typically just before starting the measurements, but not more than 24h before starting the measurements) such units shall be braked to standstill two times. Braking shall start at 80 km/h or at the maximum unit speed in the case where it is lower than 80 km/h. The unit shall be braked until a complete stop with a deceleration which is typical in normal operation, but which ensures that no wheel flats are generated.

E3.4.   Train composition (adjacent vehicles)

Noise from other parts of the train shall not influence the measurements of the unit(s) under test. Therefore, for the measurement of a trailed unit, there shall be an acoustically neutral vehicle on one side of at least two units under test, and no vehicle or an acoustically neutral vehicle on the other side. For the measurement of locomotives the adjacent vehicle shall be acoustically neutral.

An adjacent vehicle shall be considered to be acoustically neutral if:

| (a) | it is a vehicle of the same type as the unit(s) under test, or |
| --- | --- |

(a)

it is a vehicle of the same type as the unit(s) under test, or

| (b) | the LpAeq,Tp1
  is no more than 2.0 dB greater than LpAeq,Tp
  where the passing times Tp1
  and Tp
  are indicated in Figure 6 (for this evaluation round values to one decimal place). |
| --- | --- |

(b)

the LpAeq,Tp1
  is no more than 2.0 dB greater than LpAeq,Tp
  where the passing times Tp1
  and Tp
  are indicated in Figure 6 (for this evaluation round values to one decimal place).

This condition shall be verified and documented at least once for each tested speed.

Figure 6

Passing time for assessing acoustic neutrality of adjacent vehicle(s)

E4.   Measurement positions

The measurement position shall be located at a distance of 7,5 m from the centre line of the track at a height of 1,2 m above top of rail.

Measurement shall be carried out on both sides of the unit. If both sides of the unit are identical (axisymmetric or point symmetric) then it is permissible to omit the measurement points on one side of the unit.

E5.   Measured quantities

The basic measured acoustic quantities are L
  pAeq,Tp
  , train speed and pass-by time Tp
  . If required due to the use of the small deviations method as described in annex B of TSI, the frequency spectrum also needs to be determined.

E6.   Test procedure

A series of at least three measurements shall be made at each measurement position and for each measurement condition (one vehicle condition at one speed).

The validity of the measurements shall be assessed against the background noise level (see under heading ‘Background sound pressure level’ in this annex) as well as the acceptable spread of the measurement samples (Where a series of three measurement samples are required, a spread of less than or equal to 3 dB shall be fulfilled for the measurement to be considered as valid. Otherwise, additional measurements shall be made.).

E6.1.   Pass-by speeds

The speeds of testing are set out in points 4.2.1.1 and 4.2.2.4 of this TSI.

Over the measurement section of the track, the unit under test shall be run at the chosen speeds stabilised within ± 5 %. The speed shall be measured by a device with an accuracy better than 3 %. The speedometer of the train is permitted to be used, provided a calibration with accuracy better than 3 % is performed.

E6.2.   Recording and measurement time intervals

E6.2.1.   Recording time interval

Irrespective of the type of rolling stock being measured, the recording time interval Trec
  shall be chosen, so the record starts when the A-weighted sound pressure level is at least 10 dB lower than found when the front of the train is opposite the microphone position. The record shall not end before the A-weighted sound pressure level is 10 dB lower than found when the rear of the train is opposite the microphone position (see Figure 7).

E6.2.2.   Measurement time intervals – general cases

For multiple units or fixed train formations, the measurement time interval T shall coincide with the pass-by time Tp
  of the whole unit past the measuring point.

Locomotives or driving trailers shall always be tested at the head of a test train. The measurement time interval T shall coincide with the pass-by time Tp
  of the whole unit (over buffers) past the measuring point (see Figure 8).

For trailed unit(s) which form part of a train, the measurement time interval T shall start when the centre of the first unit passes the measurement position (T1
  ) and ends when the centre of the last unit passes the measurement position (T2
  ). This procedure is only applicable where at least two units of the type under test are available. The following point on ‘Measurement time intervals – Special cases’ provides acceptable test procedures for the described special cases of trailer units.

When measuring a unit within a train, the unit shall be located using an independent device, such as an optical trigger or a wheel detector.

Figure 9 shows the minimum measurement time interval Tmin
  required for the measurement of a trailer unit.

E6.2.3.   Measurement time intervals – special cases

Only when the general assessment requirements as described in point E6.2.2 of this Appendix cannot be applied due to either the physical configuration of the unit under assessment is incompatible, or the unit is a one-off unit, it is permitted to use the special assessment method following the general rules as described under the heading ‘General rules’ in this annex. The clauses as set out after the ‘general rules’ define the application of the general rules to specific types of units.

E6.2.3.1.   General rules

| (a) | In any case adjacent vehicle(s) shall be acoustically neutral and therefore fulfil the conditions specified in section ‘Train composition (adjacent vehicles)’ of this annex. |
| --- | --- |

(a)

| (b) | The measurement time interval chosen shall allow the assessment of the whole acoustic signature of the unit under test. Therefore the minimum measurement time interval Tmin
  shall correspond to the pass-by time (or a multiple of it) of this unit past the measurement position. |
| --- | --- |

(b)

| (c) | The measurement time interval shall begin when the centre of the longest segment between two consecutive wheelsets passes the microphone and ends after the same position of the last unit under test passes the microphone. |
| --- | --- |

(c)

E6.2.3.2.   Units with wheelsets located at or close to their centre

In some configurations, the wheelsets are located close to or directly at the centre of the unit under test. In such a case, the minimum measurement time interval Tmin
  shall not begin when the centre of the first unit under test but when the centre of the longest segment between two consecutive wheelsets of this unit passes the measurement position. It ends after the equivalent location on the last unit passes the measurement position (see examples in Figure A.10 and Figure A.11).

E6.2.3.3.   Permanently coupled unit composed of two vehicles

Where the unit under test is composed of two permanently coupled vehicles, not necessarily identical, it is permissible to measure only one unit, provided that both vehicles are point symmetric. In such a case, T1
  corresponds to the passing of the centre of the first vehicle and T2
  corresponds to the passing of the centre of the last vehicle of the unit.

NOTE It is recommended to test such a unit at the end of the test train.

E6.2.3.4.   Measurement of a single trailer unit

When a series consists of one unit, it is permissible to measure this single unit provided that it is acoustically point symmetric.

This procedure does not apply to driving trailers.

The unit under test shall be positioned at the end of the train. The measurement time interval T shall begin when the centre of the unit passes the measurement position and ends when the noise level measured at the measurement position has decreased by at least 10 dB compared to the maximum noise level measured during pass-by of the unit (see Figure A.13).

The A-weighted equivalent pass-by noise level shall then be assessed according to

E7.   Data processing

The value of L
  pAeq,Tp shall be calculated for each measurement position. The test result shall be the arithmetic mean value of each series of measurements, rounded to the nearest integer decibel.

Where a normalisation of the pass-by noise to a reference speed is required, then this shall be performed before rounding.

If the sound pressure levels measured on each side of the unit are different; the higher sound pressure level shall be retained as final test results.

When spectra are required due to the use of the ‘small deviations’ method, they should be supplied in one-third octave bands in the range of at least [31,5 Hz – 8 000 Hz].
