The Elze–Bodenburg railway was a branch line of 23 km (14 mi) length in the Leine Uplands. Its main intermediate station was Gronau. The line is also known as the "Lower Saxon Alme Valley Railway".

The Hanoverian Southern Railway is a historical term but it is still a common name for the line between Hanover and Kassel. It is a German main line railway in Lower Saxony and is one of the oldest lines in Germany, opened between 1853 and 1856 by the Royal Hanoverian State Railways.
