The non-electrified line to Tapolca branches off the electrified main line along the southern shore at Szabadbattyán. Initially, only the first 61km to Aszófő will be electrified and this could be completed by mid-2017 in time for the Water World Championships, which will be partially held at Balatonfüred.
This would enable through electric services for visitors to the event.
The substation and control centre will be located at Aszófő and station platforms along the line will be raised as part of the project.
A second phase is planned which will extend the overhead catenary to Keszthely via Tapolca.
