The European Union aims to establish a standard gauge for all its members.

Aggression from the side of russia caused big changes on the part of European countries, because the different width of the track became a complication for the logistics chains of supply of goods. Therefore, the same track width of 1435 mm was proposed for all member states. According to Adina Valean (European Commissioner for Transport), it was the promotion of grain exports that revealed how important it is to have a functional transport system. 7 countries that are already members of the EU do not meet the key standards of this principle: the Baltic States, Spain and Portugal. But this amendment is not only for the member states of the European Union, but for all neighboring countries, which will include changes to the TEN-T regulation.
