Railway line in Germany
The VnK line is a railway line in Berlin that formerly connected the Berlin Stadtbahn in Rummelsburg with the Prussian Eastern Railway in Kaulsdorf. The acronym may stand for Verbindung nach Kaulsdorf (connection to Kaulsdorf); Verbindung nach Küstrin (connection to Küstrin) or von und nach (from and to) Kaulsdorf or Küstrin are common interpretations. The western part of the line is still in operation. This single-track electrified line links the Stadtbahn with the Berlin outer ring (German: Berliner Außenring, BAR).
