The Stendal–Uelzen railway is a mostly single-track, electrified main line and connects Stendal in the east of Altmark, Saxony-Anhalt with Uelzen in Lower Saxony.

West of the border a temporary terminus was created at Nienbergen as the former station in the Lower Saxon town of Bergen an der Dumme was 1,200 meters east of the Iron Curtain.

After the fall of the Berlin Wall in 1990, the rebuilding of the Stendal–Salzwedel–Uelzen connection was added to the list of German Unity Transport Projects (Verkehrsprojekte Deutsche Einheit).

The 17.5 km long section between Brunau and district road 1005 in Klein Gartz now has two tracks and there is also an approximately one kilometre long passing loop west of the former Kläden station; the current Kläden station is now located further to the east on a single-track section.

On Friday, an Intercity service is operated from Hamburg via Lüneburg, Uelzen and Stendal to Berlin, returning on Sunday.

[3] The existing two-track section for crossing and overhauling between Brunau-Packebusch and Rademin, which is around 17.5 kilometre long, is to be extended to the east and west.
