However, there is still an obstacle to the opening-up of the networks that we absolutely have to remove: the absence of technical interoperability, which is caused by numerous elements, including the many different types of control-command systems, stock recognition - which we are discussing here - and, in particular, track gauge.
Aga ikka eksisteerib nende avamisel takistus, mis tuleb täielikult kõrvaldada: tehnilise koostalitlusvõime puudumine, mille on põhjustanud arvukad elemendid, kaasa arvatud mitmed eri tüüpi kontrolljuhtimissüsteemid, veeremi tunnustamine - mida me siin arutame - ja eriti rööpmevahe.
