The line reopened in 2005, 25 years after it was closed by Italian State Railways (FS), and ridership has surged over the last decade to around 2 million passengers a year.
This success has led the South Tyrol government to develop plans for the electrification of the line, which will enable the introduction of half-hourly services, increase capacity, and the introduction of through trains to Bolzano.
The line will be equipped with 25 Kv 50Hz electrification and ETCS Level 2 as part of the €56m project, which will be completed by 2019.
Work is expected to begin next spring, when STA will start extending platforms and installing new pedestrian and bicycle crossings on the line.
Electrification of the line is expected to reduce CO2 emissions by 4.2 million tonnes per year.
