Hannöversche Südbahn
The first Hildesheim station was opened by the Royal Hanoverian State Railways as the terminus of the Lehrte–Nordstemmen line—the southern arm of its "Cross railway"—on 12 July 1846 to the north of the present Kaiserstraße, near the current Bahnhofsallee. After the opening of the Hanoverian Southern Railway the Cross railway was extended on 15 September 1853 to Nordstemmen Station on the Southern Railway. The reception building of the first Hildesheim railway station was a half-timbered building with a slate roof.
