The works are necessary to ensure safe and proper operation, as well as to improve the track's load capacity and to remove speed restrictions.
The Szombathely-Zalaszentiván section is of particular importance for international and suburban traffic.
The last phase will last until 9 December.
For three weeks, only replacement buses will be available on several sections, as both tracks are already affected by the works.
With the start of the track renewal, passenger trains are now running on only one track, and the line is now partially closed.
The railway company will set up a special website where passengers can find out about current transport changes.
Due to the recent extreme weather conditions, the condition of the track has deteriorated to such an extent that it needs to be reconstructed as soon as possible.
