The designation clears the way to conduct studies necessary to apply for the rail line's environmental permit, Palkovics explained. 

Documents for the project are being drafted with the aim of completing a better railway freight link between Záhony (300 km northeast of Budapest), on Hungary's eastern border, and Győr (120 km northwest), in the west of the country, by 2030, he added. 

Róbert Homolya, the chairman-CEO of Hungarian State Railways (MÁV), noted that close to half of freight trains have to pass through the capital at present. He said that the number of freight trains needs to double from around 400 a day if the transport alternative is to be competitive, but that will require network upgrades. 

The V0 bypass will include the construction of another railway bridge over the Danube. The possible location of the bridge, as well as alternatives, are being weighed, Palkovics said.
