Finally in 1898, the Leipzig city council decided on a joint terminal for Royal Saxon and Prussian state railways north of the city centre. A building contract with both organisations was signed in 1902 and an architectural competition with 76 participants was held in 1906. The winning design by the archtitects William Lossow (1852?1914) and Max Hans Kühne (1874?1942) featured two identical domed entrance halls facing the street, one for each company. The foundation stone was laid on 16 November 1909 and the platforms were gradually brought into operation station from 1912 onwards. When construction works finished on 4 December 1915, Leipzig Hauptbahnhof had become one of the world's largest railway stations with 26 platforms.
