Decision on the approval requirement for modifications to already approved vehicles

Service Description

Inform the approval body of the Federal Railway Authority (EBA) of all modifications to an already approved vehicle that go beyond maintenance work and in which components are replaced by other parts with a different function and performance. As the change management body, assign the changes to a category:

Category a:

  • Modifications without deviations from the technical documentation attached to the EC declarations of verification of the subsystems:
    • no verification by a conformity assessment body required
    • the original EC declarations of verification of the subsystems and the vehicle type approval remain valid and unchanged

Category b:

  • Modifications with deviations from the technical documentation which
    • attached to the EC declarations of verification of the subsystems, which may require new tests and therefore verification according to the relevant conformity assessment modules
    • do not affect the essential design characteristics of the vehicle type
    • do not require a new approval

Category c:

  • Modifications to the basic design features of the vehicle type:
    • for which no new approval is required

Category d:

  • Modifications for which a new approval is required

If, after classification, the modification falls under categories b or c, you as the modification administration body of the vehicle type approval of the modified vehicle must

  • assess the deviations from the technical documentation accompanying the EC declarations of verification of the subsystems,
  • update the technical file attached to the EC declarations of verification of the subsystems, and
  • inform the EBA approval body of the changes.
  • demonstrate that none of the following criteria are met:
    • In the case of renewal or upgrading of existing vehicles that already have a vehicle authorization for placing on the market, a new authorization is required if
      • changes are made to the values of the parameters referred to in the Technical Specifications for Interoperability (TSI) and, where applicable, in the national rules, for the verification of the technical compatibility of the vehicle with the area of use, and these are outside the range of acceptable parameters according to the TSI,
      • the planned work could affect the overall safety level of the vehicle concerned, or
      • it is required by the relevant TSIs .
