The deal seeks to support the regional government's objective of increasing regional passenger services by 15-20% to 3.6 million train-km per year.

The main proposals, some of which had been agreed previously, include the development of cross-border services to Slovenia and Austria, such as the Udine - Villach Micotra trains launched in 2012.

Work is already underway on a €1.8bn project to upgrade the line from Trieste to Venice via Cervignano-Aquileia-Grado, which will increase maximum line speeds from 160km/h to 200km/h and reduce journey times by up to 50 minutes. This project includes track realignment on sections with sharp curves and the elimination of level crossings.

Other commitments include measures to improve infrastructure reliability, accessibility enhancements at stations and closer integration between rail and bus services at regional hubs.
