The council says investment in the line is necessary because of sharp rises in passengers and subsequent overcrowding on the line, which is now carrying 2 million passengers per year.

Electrification is considered the best way to improve service and after the project is complete it will be possible to offer a service every 30 minutes, and use longer trains, which will transport up to 276 passengers. The line will also offer an hourly direct connection from Bolzano to Malles, without requiring a change in Merano.
