It then traverses Gifhorn district and the eastern part of the Lüneburg Heath, and reaches Wieren after passing through Wittingen, where there is a junction to the East Hanoverian Railways network, and Bad Bodenteich.

At Wieren it merges into the electrified Stendal–Uelzen railway, the eastern section of the America Line, sharing its trackbed to Uelzen.

Running roughly parallel to the railway, but at distance of a few kilometres, are the Elbe Lateral Canal, which is crossed twice, the B 4 federal road and the planned route of the A 39 motorway.

Following an extensive relaying of the track, from 1913 trains could approach the station from the east which shortened journey times.

In early 2008 the urban level crossings in Meine were replaced and the bridge over the Midland Canal near Bechtsbüttel renovated.

In 2014, the track was renewed between Stöcken and Bad Bodenteich, where it connects with the subsequently constructed island platform, which enables the crossings of the few trains that have run hourly since December 2014.

The platforms were adapted in whole or in part to the entry height of the new railcars in the stations of Gifhorn Stadt, Neudorf-Platendorf, Wahrenholz and Knesebeck.

Until December 2014, Regionalbahn trains operated by DB Regio provided passenger services more-or-less every 2 hours, usually using Class 628 diesel multiple units.

[4][5] Since December 2014, the line has been operated by the erixx railway company based in Soltau with Lint 54 railcars.

[7][8] Freight traffic still operates from and to Knesebeck (timber loading, a siding to the firm of Butting), from and to the port of Wittingen as well as south of Braunschweig-Gliesmarode.

There are sometimes traffic jams at the level crossings near Meine (federal route 4) and Ausbüttel due to defective barriers.

Several stations and halts would have been rebuilt and the number of trains on this line would have been increased to match the more frequent intervals of the RegioStadtBahn.

The project failed in 2010, because significantly increased vehicle procurement costs meant that it was no longer economically viable.

In order to be able to increase the attractiveness of the regional train services even without the RegionalStadtBahn, the Zweckverband Großraum Braunschweig (Greater Brunswick Municipal Association, ZGB) developed the Regionalbahnkonzept 2014+ concept.

For a long time passenger trains hauled by DB Class 218 diesel locomotives dominated the scene.
