Further important railway lines in Tyrol are the Arlberg railway, Zillertal railway, Salzburg-Tyrol railway, Pustertal railway with continuation of the Drautal railway, the railway line Bolzano-Merano and the continuation of the Vinschgau railway, the Trento-Malè-Mezzana railway and the Valsugana railway, which leads from Trento to Venice over the Sugana Valley. Cross-border connections are offered only a few. The ÖBB travels over the Brenner Pass on the Eurocity trains and several regional trains connect South Tyrol with North Tyrol an East Tyrol. The Euroregion Tyrol-South Tyrol-Trentino has set itself the goal of promoting and expanding cross-border connections. The aim is to shift traffic through the Alps to sustainable means of transport, thus protecting the Alpine environment.
