The line is to be upgraded at a total cost of €952 million (as of 2013). The first and third of three sections designated under this project have been completed. The planning approval procedure for the second section, which includes passing tracks and increased speeds, was initiated at the Federal Railway Authority in August 2014. The works are divided into six phases of construction with commissioning due in the second quarter of 2020. Preparatory work began in June 2018.
