The Kremmen Railway is a line in northern Berlin and Brandenburg, Germany. It branches off the Prussian Northern Railway in the Berlin district of Reinickendorf, north of Schönholz station and then passes through Tegel, Hennigsdorf and Velten to Kremmen. There it connects with the Kremmen–Meyenburg line opened in 1898 to Neuruppin.

The Berlin Northern Railway is a 223-kilometre-long main line route, that runs from Berlin via Neustrelitz and Neubrandenburg to Stralsund on the Baltic Sea coast. Nowadays, long-distance and regional traffic on the Nordbahn is routed at Hohen Neuendorf onto the Berlin Outer Ring to the Karower Kreuz and on to Berlin Main Station or Berlin-Lichtenberg.
