The Leipzig–Dresden Railway Company (Leipzig-Dresdner Eisenbahn-Compagnie) or LDE was a private railway company in the Kingdom of Saxony, now a part of Germany. Amongst other things, it operated the route between Leipzig and Dresden, opened in 1839, and which was the first long-distance railway line in Germany. On 1 July 1876 the company was nationalised and became part of the Royal Saxon State Railways.
The idea of building a railway to link Leipzig with Strehla (on the river Elbe), had already been put forward before 1830 by the Leipzig merchant, Carl Gottlieb Tenner. Tenner's idea gained new impetus after the state economist in Leipzig, Friedrich List, publicised his plans for a German railway system in 1833, in which it was envisaged that Leipzig would function as a central hub. That same year, a railway committee was founded which, on 20 November 1833, submitted a petition to the lower house of the Saxon Parliament (Sächsischer Landtag) in Dresden for the construction of a railway from Leipzig to Dresden .
In 1835, the Leipzig–Dresden Railway Company was founded as a private company by twelve citizens of Leipzig, including: Albert Dufour-Féronce (1798–1861), Gustav Harkort (1795–1865), Carl Lampe (1804–1889) and Wilhelm Theodor Seyfferth (1807–1881). At the Easter trade fair in 1835 the shares of the company (nominally valued at 100 thaler) were fully subscribed within just a few hours, making a capital sum of over one million thalers available. On 6 May 1835 the Saxon state government authorised the construction and operation of the line as well as the issue of non-interest bearing bonds to the value of 500,000 thalers. The total capital generated thus amounted to 1.5 million thalers.
In October 1835 the British engineers Sir James Walker and Hawkshaw surveyed the proposed routes and recommended the northern route via Strehla (estimated cost: 1,808,500 thalers) over the route via Meißen (1,956,000 thalers). On 16 November 1835 the purchase of land began for the section between Leipzig and the Mulde bridge north of Wurzen. On 1 March 1836 the first sod was cut. Oversight for the entire project lay in the hands of the Saxon Senior Waterways Construction Engineer (Oberwasserbaudirektors), Karl Theodor Kunz. Then however the town council of Strehla rejected the building of the railway. So the line was re-routed over the river Elbe 7 km further south at Riesa. On 7 April 1839 the first train ran over the Elbe railway bridge at Riesa.
