Brunswick–Magdeburg railway

The BPME considered several options for a dedicated connection between its main line and the former Duchy of Brunswick State Railway network, which had been privatised and was now the Brunswick Railway Company (Braunschweigische Eisenbahngesellschaft). While it was clear that its eastern end would be in Magdeburg, in the west several variants were discussed. Brunswick was an important destination and connected well to the west, but had an unfavourable terminal station. It was decided to build a line from Magdeburg to Eilsleben, where it would branch to Helmstedt and Schöningen. From Helmstedt the Brunswick Railway Company would continue the line to Brunswick, while in Schöningen there had been since 1868 a connection to Jerxheim, which had a link to Börßum and the Brunswick Southern Railway to Kreiensen. It there connected with Göttingen and Kassel via the Hanoverian Southern Railway and via Altenbeken to the Ruhr district via the Altenbeken–Kreiensen railway. This gave the new line the same connections to the west as the MHE’s main line.

Between Eilsleben and Brunswick the line crosses the Lappwald ridge and the Elm hills. The line is winding and passes over embankments and through cuttings. The line was opened on 15 September 1872.

While the Berlin–Lehrte line, opened a year earlier, remained the fastest line for passenger between Hanover and Berlin, the line via Helmstedt also carried passenger traffic between the two cities and traffic from Hanover to Halle and Leipzig. In addition, substantial freight traffic was carried on both branches. In 1937 five express trains ran each day each way on the line.

Since the line passed through relatively undemanding terrain and has no large structures, it was only impassable for a few days during and after World War II. The allies decided to use this line exclusively for the military transport of the Western powers in Berlin. The Berlin–Lehrte line remained usable, but was used less.

In 1960, the current Brunswick Hauptbahnhof opened, which removed the need for trains between Magdeburg and Hanover to reverse.

Rail transport between Helmstedt and Eilsleben was reopened under the Transit Agreement of 1972. In the 1980s, there were negotiations between West Germany and East Germany over an expansion of the transit routes. East Germany preferred the Lehrte line, to keep transit traffic out of Potsdam and Magdeburg. In the West, however, there were discussions of improved connections with Brunswick.

After the fall of the wall it was quickly decided to build a high-speed line between Hanover and Berlin. However, it was also clear that the construction would take several years. The initial experience with speed lines also showed that a separation of freight and high speed passenger traffic made sense. Under the German Unity Transport Projects, it was decided to restore as quickly as possible the existing routes and to electrify lines that were intended primarily for freight later. The core of this plan was the Helmstedt–Magdeburg line. In 1993 it was upgraded for operations at 160 km/h and electrified. In the east it connected with the Biederitz–Dessau line, which in turn connected at Güterglück with a now closed section of the former Canon railway, leading to Berlin. The direct line to Berlin via Brandenburg (Havel) and Potsdam was electrified in 1995.

In 1991 the first diesel-powered Intercity train ran from Hanover via Brunswick and Magdeburg to Berlin. Two years later the first Intercity-Express (ICE) ran on the line. The major change came in 1998 when the Hanover–Berlin high-speed line opened. Since then, the hourly ICE trains between Frankfurt and Berlin run on the line only on the 5 km section between Brunswick and the junction with the Weddel loop.
