Since 1991, the European railway sector has constantly been reformed by the European Union. The 4th Railway Package, which was adopted in 2016 is by far the largest and most complex legal initiative introduced so far. The 4th Railway Package consists of a political and a technical pillar which introduce substantial reforms for all stakeholders concerned.
This Guide illustrates in four different chapters the reforms in the field of vehicle authorisation, safety certification and ERTMS trackside approval as well as the new role of the European Union Agency for Railways as ‘frequently asked questions’. Given the fact that the implementation of the 4th Railway Package is an ongoing process, the Guide will be updated on a regular basis, in line with the progress of the reforms being made on EU level.

Directive 2016/797 defines the procedure for vehicle authorisation and ERTMS track-side approval:
 Directive 2016/797 stipulates that all applications, whether they are national or international, will have to be submitted and processed via the ERA IT tool. This will then also involve cases which are handled by national actors only (i.e. the NSA and the national applicant) for national vehicle authorisations. This will imply that NSAs review their processes.
