STRAILastic_A INOX 2.0 is a rail damper for decreasing sound emission and reducing rail

vibrations. In order to make it more efficient, the rail damper contains steel inserts which

increase its dead weight. The rail dampers are fastened directly to the rail foot using steel

clamps. The STRAILastic_A INOX 2.0 rail damper is based on the STRAILastic_A INOX 1.0

rail damper which has been approved for field testing. The geometry has been changed

but the materials used are still the same.

II. The approval for field testing is given at the basis of the following supporting

documents and drawings. Those have been essential for our decision and have to be

observed unless the secondary regulations say otherwise.

• Request for supplementing the approval for field testing of rail damper

STRAILastic_A INOX 2.0 from 27th August 2015 – Mr. Sinzinger;

• Installation Instructions STRAILastic_A INOX 2.0 from August 2015;

• Technical data sheet STRAILastic_A INOX 2.0 from 26th August 2015;

• System drawing rail damper 01891200-60kg STRAILastic_A INOX rail 60 kg from

28th April 2015;

• Drawing fixing clamp 02085000_AU STRAILastic_A Clamp INOX from 16th March

2015;

• Drawing absorber element 02082600_AU STRAILastic_A Absorber INOX from 28th

April 2015;

III. The approval for field testing is connected to the following secondary regulations:

1. Alterations made to the rail damper STRAILastic_A INOX 2.0 which regard its

structure and which are relevant to safety have to be reported to the Federal Railway

Authority (EBA) in advance. In case of a safety-related breakdown or failure of the

STRAILastic_A INOX 2.0 rail damper, the EBA has to be informed immediately. The EBA will

then decide about the appropriate procedure.

2. A copy of the approval for field testing and the supporting technical documents

have to be presented to the builder-owner prior to the beginning of the building measure.

It must be ensured that copies of the approval for field testing and of the supporting

technical documents are available at the building site as well as at the local responsible

authorities during the field testing.

3. The manufacturer’s installation, repair and maintenance instructions and the

necessary tools for it have to be held available at the building site and for the operator.

4. The STRAILastic_A INOX 2.0 rail damper must not be set up in the area of turnouts

or other moveable parts or in the area of line or wire connections, connectors or wire

contacts.

5. When mounted on welding beads, the STRAILastic_A INOX 2.0 rail dampers must

be processed accordingly.

3

6. At points which are constructional secured with emergency rail clamps, the

STRAILastic_A INOX 2.0 rail dampers must first be removed residue-free. The same goes

for a subsequent installation of LST components.

7. After mechanical maintenance work, the correct position of the STRAILastic_A INOX

2.0 rail dampers must be checked.

8. Labelling the STRAILastic_A INOX 2.0 rail dampers must be done in accordance

with the Railway Infrastructure Company. The rolling label on the rail web according to

DIN EN 13674-1 has to be transferred permanently to the STRAILastic_A INOX 2.0 rail

damper.

9. For return circuit currents, railway earthing and equipotential bonding, regulations

according to Business Unit Guideline 997.02 by DB AG are decisive. The regulations of the

DIN standards, especially those of DIN EN 50122-1, have to be observed.

10. The necessary electro technical and safety-related measures have to be arranged

with the Railway Infrastructure Company.

11. Before STRAILastic_A INOX 2.0 rail dampers are used in tunnels, there has to be

proof of their non-combustibility according to EBA guideline “Anforderungen des Brand-

und Katastrophenschutzes an den Bau und den Betrieb in Eisenbahntunneln” (Fire and

Desaster Protection Requirements for the Construction and Operation of Railway Tunnels).

12. It must be ensured that Federal Railways (EdB), normally DB AG, technically monitors

the building projects in cooperation with the manufacturer and closely supervises them in

the context of regular inspections during the stage of field testing. Visual checks have to

focus especially on the force-locked fastening of the STRAILastic_A INOX 2.0 rail dampers

to the rails, on deformations (e.g. distortion, warping) and on the surface (e.g. damage

caused by UV) of the STRAILastic_A INOX 2.0 rail dampers. The results of the tests and

checks as well as any work done on the superstructure during the field testing stage have

to be documented and collected in a “field testing journal”. The place and the date of the

beginning of the field testing have to be sent to the EBA in writing.

13. STRAILastic_A INOX 2.0 rail dampers have to be subjected to continuous quality

control according to DIN 18200. Internal quality control tests can be done in internal labs

and test benches. External quality control has to be carried out by an acknowledged

institute such as Deutsche Bahn AG, Beschaffung Infrastruktur, Lieferantenmanagement

und Qualitätssicherung, Caroline-Michaelis-Straße 5-11, 10115 Berlin.

14. The requirements as well as the type, scope and frequency of tests carried out in the

context of internal and external supervision have to be described in quality control

instructions by the manufacturer in cooperation with the certifying body and presented to

the EBA for inspection.

4

15. The confirmation that the STRAILastic_A INOX 2.0 rail dampers comply with the

regulations of this approval has to be done with a certificate of compliance (proof of

compliance) according to the following sample:

Proportion of dimensions (outer dimensions)

W : H = 0.75 (≥ 4.5 cm : 6.0 cm)

16. The above-shown certificate of compliance has to be attached to the STRAILastic_A

INOX 2.0 rail damper or if that is not possible, to the dispatch note.

IV. Reservation:

This approval can be revoked with immediate effect if its secondary regulations are not

observed. This approval will be revoked, supplemented or amended if the STRAILastic_A

INOX 2.0 rail damper does not stand the test, especially if repeated damage is caused

which can be attributed to the use of STRAILastic_A INOX 2.0 rail dampers or if new

technical information may suggest it.

V. The cost of the proceedings will be borne by the applicant.

VI. Note:

1. This approval is given without prejudice to the rights of Third Parties, especially

private property rights.

2. An extension of this approval for field testing or a (general) approval has to be

requested at the respective office at least 6 months prior to the expiration of its validity

and all essential documents and field testing results have to be included.

For processing the application for (general) approval, the following additional documents

have to be submitted:

5

a. Description of possible changes between the approval for field testing and the

application for (general) approval:

b. Summary of the field testing results hitherto existing including a concluding

technical evaluation and estimate regarding the fitness for service and safety by a special

expert service of the Railway operator.

3. The operating Railway infrastructure company regulates in its own responsibility

which types of superstructures are used. For the approval by the Federal Railway

Authority, safety-relevant aspects are especially important. However, prior to actual use in

the tracks, the operator may require additional criteria which are not relevant for our

official approval. Therefore, independent of the official approval, we recommend

contacting the responsible departments of the operating railway company in time in order

to get a statement of the operator containing his requirements.

4. For use in the area of the Trans European Railway Network (TEN), we refer to the

requirements of Ril 2008/57/EG and the corresponding Technical Specifications (TSI).

5. This approval does not neither replace a plan approval procedure which might be

necessary according to § 18 AEG nor general building approval according to VV BAU and

VV BAU STE.

6. This approval for field testing does not include any statement about an acoustic

evaluation.

Reasons:Reasons:Reasons:Reasons:

The Federal Railway Authority is responsible for granting construction permits, approvals

and authorisations as well as acceptance, investigations and supervision regarding the

construction, alteration, maintenance and operation of facilities of the Federal Railways

according to § 3 of German law “Bundeseisenbahnverwaltungsgesetz – BEVVG) from 27th

Dec 1993 (BGBI. I pages 2378, 2394, current version) in connection with § 4 Paragraph 6

of the general Railway law “Allgemeines Eisenbahngesetz (AEG)” from 27th Dec 1993

(BGBI. I pages 2378, 2396, 1994 I S. 2439 current version).

Approval for field testing is required since the STRAILastic_A INOX 2.0 rail damper is a

sleeper type which has not been tested enough yet.

On the basis of our current knowledge, approval for field testing can be given since the

comparable rail damper STRAILastic_A INOX 1.0 has been approved for field testing by

EBA decision 21.63-21 izbo/016-2101#026-(512/12-ZzB) from 24th Sep 2012 and installed

in railway tracks of DB AG and there have been no indications which argue against an

approval for field testing STRAILastic_A INOX 2.0 rail dampers.

6

When used and monitored properly, there are neither technical nor safety-relevant

concerns about the use of the STRAILastic_A INOX 2.0 rail damper in railway tracks of

Federal Railways.

The order of secondary regulations is necessary for the safety of railway operations.

The technical codes are constantly updated and have to be observed in their latest

versions.

The costs for processing this application comply with § 3 Paragraph 4 sentence 1 (BEVVG)

in connection with the “Verordnung über die Gebühren und Auslagen für

Amtshandlungen der Eisenbahnverkehrsverwaltung des Bundes (BEGebV) from 27th March

2008 (BGBGI. I. page 546) in the current version. The invoice will be sent by separate mail.
