Lüchow-Schmarsauer Eisenbahn GmbH (LSE) was founded on 16 April 1910 as Kleinbahn Lüchow-Schmarsau GmbH and opened the first full-gauge line on 14 December 1911. Operations included passenger and freight transport on rails and roads. The main shareholders were the Prussian state, the province of Hanover, whose shares were transferred to the state of Lower Saxony in 1945, and the former district of Lüchow. Currently the Lüchow-Dannenberg district sole shareholder.
Rail transport was discontinued in 1969 and the first bus was purchased. Since that year, LSE has been operating passenger transport by bus, which was already characterised by school transport at the time. LSE currently only operates passenger transport in the form of licensed regular bus services and hire services in the Lüchow-Dannenberg district.
The LSE office is located on the company premises in Roland-Brandin-Straße in Lüchow. LSE not only operates public transport in the Lüchow Dannenberg district, but is also active across the district and runs services as far as Dömitz and Uelzen in partnership with neighbouring transport companies. As a contribution to climate protection, LSE bears the "Blue Angel" eco-label and operates at least
with EURO IV/EEV. On 14 December 2011, the LSE turned 100 and celebrated its anniversary.
