The Lehrte – Nordstemmen line is a double-track , electrified main line in Lower Saxony . It connects the Lehrte railway junction with the Hildesheim main train station and the Nordstemmen train station on the Hanover Southern Railway .

history

The Lehrte – Hildesheim connection was planned as the south branch of the “Kreuzbahn” together with the Hanover – Braunschweig and Lehrte – Celle lines by the Hanover State Railways and opened on July 12, 1846, making it one of the oldest lines in the history of the railway in Germany . The hitherto insignificant teaching became a railway junction, since the then King Ernst August I was skeptical of the means of transport and did not want any larger railway facilities in his residence.

This attitude changed under his son George V. In 1853 the Hannöversche Südbahn from Hanover to Alfeld (Leine) was opened, which begins directly in the state capital and runs parallel to the Kreuzbahn a few kilometers away. Hildesheim received a connecting line to the southern railway (opened September 15, 1853), which connects to the southern railway at Nordstemmen station. This originally single-track line was expanded to double tracks in 1875 by the Hanover-Altenbekener Eisenbahn-Gesellschaft in order to continue its westward Elze – Löhne railway eastward via Hildesheim to Vienenburg.

After the southern railway was extended to Kassel until 1856 , traffic from Harburg via Celle , Lehrte and Hildesheim was now possible via Kassel to Frankfurt . Mainly freight trains took this route, passenger traffic made the detour via Hanover. In Nordstemmen, this traffic met those from Bremen and Hanover . Only with the completion of the Hanover freight bypass (1909) existed two equivalent routes from Lehrte to the south.

Industry developed along the Lehrte – Hildesheim route, and potash was extracted in several shafts .

Electrical operation on the Nordstemmen – Lehrte line began on May 29, 1965.

Realignment in Lehrte

The historical route left the Lehrte station shortly after the platforms in a direct, southern guidance. As a result, the place was cut up, and north-south and east-west traffic was hindered by the level crossing in the Lehrte train station.

Therefore, before the construction of the high-speed line Hanover-Berlin between Lehrte and Sehnde in 1990 , the Hildesheim line was extended to the east by about two kilometers, parallel to the line towards Braunschweig, an overpass over this and now meets it again after a large bend old track towards Hildesheim.

With the further expansion of the Lehrte junction, the connections from the east and south were redesigned to be free of intersections by 2008. The passenger trains from Wolfsburg, Braunschweig and Hildesheim were concentrated on the southwest side, the freight trains on the northeast side of the station, only the S-Bahn from and towards Celle and Hildesheim still run on the northeast side.

course

The route originally ran almost in a straight line between Lehrte and Hildesheim . Since the beginning of the 1990s it has been leaving Lehrte together with the Hanover – Braunschweig railway in an easterly direction. It makes a curve of almost 180 ° to the west and meets the old route again south of Lehrte.

Now it goes south through largely flat terrain via Sehnde , Algermissen and Harsum to Hildesheim and from there from the east to the main station .

A regional train in the direction of Hanover crosses the Escherde depot on a bridge (around 1991)

From there on, the route runs straight west to Nordstemmen . Since 1991 it has been crossing the high-speed line from Hanover to Würzburg , to which it is connected via the Hildesheim loop to the south. At the end of the line there has also been a single-track connecting curve to the north since 1893, which merges into the southern runway at Barnten station.

Todays situation

Today the route is mainly used for goods and local passenger transport.

Since December 14, 2008 the S-Bahn line S3 (Hanover–) Lehrte – Hildesheim and the S-Bahn line S4 (Bennemühlen – Hanover–) Barnten – Hildesheim have been running every hour instead of the previous regional trains. Intermediate stations were also rebuilt for this purpose. On the Barnten (on the Hannöverschen Südbahn) –Hildesheim line, the regional express trains to Harz are added. Trains of the NordWestBahn run every hour on the Nordstemmen – Hildesheim route . With the long-distance trains from the Hildesheim loop that are also coming, this section of the route is densely occupied.

At Sehnde there are sidings to the Bergmannssegen-Hugo potash plant in the north (production of granulate fertilizer) and to the former Friedrichshall potash plant in the south (brine loading for Bergmannssegen-Hugo).

planning

Another stop is to be built in Hildesheim-Himmelsthür. This was agreed on March 28, 2019 between the state of Lower Saxony, LNVG and DB.
