Key legal question
Whether the mobile telecommunications installation along the railway corridor is an Eisenbahnanlage under Art. 18 EBG or a Nebenanlage under Art. 18m EBG.
Extracted holding
The antennas are not railway installations because they do not primarily serve railway operation; they mainly serve mobile telephony for passengers.
Extracted reasoning
Railway-planning approval applies only to facilities that, viewed functionally, are necessary for railway operation. The project is independently operated by telecom providers, is technically and functionally autonomous, and is comparable to passenger-serving but non-operational facilities such as a kiosk.
