The works were delivered by SWIETELSKY Railway Construction Austria, with an emphasis on precise execution and efficient coordination throughout the tight construction window. A major part of the programme focused on renewing key sections of track: around 1,500 metres were rebuilt including subgrade rehabilitation. Here, a special stabilization method was applied that optimized the process, helped keep costs under control for the client, and supported delivery within the demanding schedule. In addition, a further 2,900 metres of track were renewed with new rails and ties, improving both ride quality and operational safety.

Beyond the running track itself, the project also took a strategic step toward future capacity growth. Two concrete switches were installed as an early but crucial component for the planned double-track expansion. Supporting infrastructure was upgraded as well, with extensive drainage and trench works completed along the line—ranging from deep drainage and drainage slits to railway trench construction, trench wall sections, and concrete shell installations. As part of the underground cable construction, approximately 5,400 metres of concrete cable trough (size III) were installed, creating a robust base for modern railway systems.
