The Trento–Venice railway is an Italian state-owned railway line connecting Trento, in Trentino-Alto Adige, to Mestre, a suburb of Venice, in the Veneto region. At Mestre, it connects to the main line from Verona.
The line is managed by RFI, a company of the Ferrovie dello Stato group. Passenger traffic is urun by Trenitalia, which also runs regional trains ordered by the Veneto region; in the province of Trento, Trentino Trasporti fulfills this role (line 401).
Railway lines had been built from Trento, in what was then part of Austria-Hungary, in 1859 southwards to Verona, and in 1867 northwards to Bolzano and the Brenner pass; today these form the Brenner Railway, the main railway connection between Italy and Austria. On the Italian side a line was built from Bassano del Grappa to Padua in 1877, and an extension to the Italian-Austrian border at Primolano was studied. However, when the Veneto joined the Kingdom of Italy, a new border was established at Tezze, and hence the Austrians constructed a railway from Trento to Tezze in 1896, where it joined the Italian Valsugana railway line.
On the Italian side, the line from Mestre via Primolano to the border was built between 1906 and 1910, with the first part, to Bassano del Grappa, opening in 1908, and a second to Carpanè Valstagna the following year. Primolano now became an international border station, though only for a few years, as Trentino-Alto Adige became part of Italy after the First World War.
