S-Bahn Nürnberg
In the course of the second stage of the Nuremberg S-Bahn (planning status: 1981), it was planned to establish S-Bahn operations on the section between Fürth and Siegelsdorf, which would be upgraded. In addition, planning investigations were carried out in 1987. These plans have not been implemented so far (as of 2013). An upgrade to three tracks between Siegelsdorf and Fürth is planned in the Federal Transport Infrastructure Plan for 2030.
