Brunswick State Railway Company

It was founded on 27 June 1884 by the Frankfurt bank of Erlanger & Söhne and Gebrüder Sulzbach with the aim of building and operating railways of secondary importance in the Duchy of Brunswick and the adjoining territories.

They provided rail access for about 50 commercial firms and around one hundred warehouses in the city of Brunswick using a ring railway.

From here it ran to Braunschweig West (Wilhelmithor) and southwards to Hoheweg, where on 17 October 1886 a 4 km long branch to Wolfenbüttel turned off.

The main line swung westwards and reached Derneburg station on the Hildesheim–Goslar railway via Lichtenberg and Osterlinde in what later became the Salzgitter industrial estate.

The creation of a large industrial complex in the area of Salzgitter required a fundamental change and expansion of the railway network there.
