This is a part of the switchboard at Konstanz. The upper tracks
belong to Konstanz-Petershausen on the line to Radolfzell and
Singen (Hohentwiel). The very left part, the southern side, leads
to Kreuzlingen, in fact, the whole railway yard where the IR and
other trains are put, belongs to Swiss territory.
