The energy measurement systems of existing vehicles must comply with the requirements of EN 50463 (the 2012 or later version), with the exception detailed in Point 2.2.2 of this Annex. The conformity of the systems must have been confirmed by a conformity assessment body.

Energy measurement systems of existing vehicles which do not meet all the requirements of Point 2.1 or 2.2.1 of this Annex may nevertheless be approved for the actual billing of traction current after consultation with the infrastructure manager (IM). The energy measuring systems must comply with the implementing provisions set out below. The conformity of the systems must have been confirmed by a conformity assessment body.

The following documents must be submitted to the IM in order to register a vehicle: 

• Registration form (Point 3.1.3) 
• Conformity certification documents by type of vehicle (Point 3.1.4.) 
• Conformity certification documents by locomotive (Point 3.1.5.) 
• Calibration certificates for each system component (Point 3.1.6)

The following documents must be submitted to the IM in order to register a vehicle: 

• Registration form (Point 3.1.3) 
• Conformity certification documents by locomotive (Point 3.1.5.) 
• Calibration certificates for each system component (Point 3.1.6)

The registration form can be obtained on written request from SBB Infrastructure (onestopshop@sbb.ch). The applicant (train operating company, vehicle keeper, manufacturer, etc.) should submit the completed registration form to SBB Infrastructure together with the other documents listed at Point 3.1.1 and/or 3.1.2.

The following conformity certification documents must be submitted to the IM in respect of each vehicle type (e.g. Re 420, RABe 521, etc.) and each equipment type (integration of a specific combination of voltage transformer, current transformer, measurement device and/or other components of the energy measurement system): 

a) For energy measurement systems conforming to TSI LOC & PAS (EU Regulation 1302/2014 or later) in accordance with Point 2.1: an assessment report incl. a test certificate issued by a conformity assessment body 

or 

b) For existing vehicles with energy measurement systems conforming to EN50463 in accordance with Point 2.2.1: an assessment report from a conformity assessment body (incl. confirmation of conformity) 

or 

c) For existing vehicles with energy measurement systems deviating from the TSI or EN 50463 (as defined in Point 2.2.2): an assessment report from a conformity assessment body; this report must also identify the deviations from the requirements and assess whether the deviations are in conformity. 

A routine test report in respect of every energy measurement system installed on the vehicle must be submitted to the infrastructure manager. 

The report is to contain at least the following data on the energy measurement system: 

• The date of installation 
• The installation location 
• The designation, class and scale of the voltage transformer (only if applicable) 
• The designation, class and scale of the current transformer (only if applicable) 
• The complete EVN, as well as all CPIDs for the energy measurement systems installed in the vehicle. 
• The designation and serial number of the energy calculation function/energy measurement device/meter 
• The reference to the assessment report and the EN 50463 conformity certificate or to the EC test certificate

A calibration certificate must be submitted for each "Energy Calculation Function" system component. This calibration certificate must, among other things, include the date on which the calibration ceases to be valid. If this expiry date is exceeded, the energy measurement system will no longer be in conformity.

The purpose of the monitoring phase is to verify that the energy measurement system is working correctly. During the monitoring phase, the consumption values per train type as published in the infrastructure performance catalogue will be used. In order that the monitoring phase can be completed within two months, the following requirements must be met at the same time: 

• The vehicle must be operated in Switzerland. 
• The vehicle must be in use for at least 10 operating days. 
• In this time, the energy measurement system provides complete data. 
• In this time, complete data is also provided via the railway operating systems (EVN). 

After successful completion of the monitoring phase, the vehicle will be activated for actual billing and the vehicle keeper will receive corresponding confirmation. 

If a vehicle is approved for the actual billing of traction current, energy will be billed exclusively on the basis of the readings taken on the vehicle, irrespective of which train operating company is using the vehicle.
