Modify once, approve the whole series.
Series modification approval covers vehicles modified in series: the same change applied across a run of vehicles. As an STB-appointed technical service (E37), we assess the modification against every regulation it affects, run the tests and prepare the technical file for the approval authority.
Modifying a single vehicle? Individual Approval covers one-off vehicles.
