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.

[6] 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,[7] though only for a few years, as Trentino-Alto Adige became part of Italy after the First World War.

For this service, new trains of the Minuetto type were bought by Trentino Trasporti in order to replace the old FS Class ALn 668.

All of it is standard gauge, and the line is electrified at 3000 V from Mestre to Bassano del Grappa, where the maximum speed is 120–140 km/h (75–87 mph).
