U radu autor s aspekta povijesti institucija obrađuje ustroj i djelovanje Dioničarskog društva vicinalne željeznice Szt. Lörincz-Slatina-Našice u periodu od godine 1894., kada je društvo osnovano sa sjedištem u Budimpešti, pa sve do godine 1948., kada je tadašnja aktualna vlast i formalno-pravno legalizirala nacionalizaciju privatnih privrednih poduzeća. Dio pruga na području Kraljevine Hrvatske i Slavonije nalazio se u potpunosti u Virovitičkoj županiji. U Kraljevini Srba, Hrvata i Slovenaca društvo je premjestilo svoje sjedište u Beograd. Poslove dioničarskog društva obavljali su glavna skupština dioničara, ravnateljstvo i nadzorni odbor. Pruge društva bile su u državnoj eksploataciji, odnosno upravi. Društvo je u Austro-Ugarskoj Monarhiji poslovalo s financijskim dobitkom. In the paper the author outlines from the aspect of the history of institutions the structure and the activity of the Szt. Lörincz-Slatina-Našice Vicinal Railway Ltd. in the timeframe from its establishment in 1894, the buying off of the railway tracks in its ownership by the state in 1938, the transfer of ownership of bought railway tracks in the Central cadastral book of railways and canals to the State in 1939, ending with 1948 when the government of the time formally legalised the nationalisation of private economic companies. The following railways made the company’s railway network: Baranya-Szent-Lörincz-Baranya Sellye put in service on 21 May 1895, Baranya Sellye-Našice put in service on 23 December 1895, and the branch line Noskovci-Drava riverbank put in service on 9 July 1901. The stock company’s railway lines directly connected the Kingdom of Croatia and Slavonia with Hungary, which enabled the faster flow of goods and wares in both directions. The part of the railway line in the territory of the Kingdom of Croatia and Slavonia was completely in the Virovitica County. As with most vicinal railways, the company’s headquarters was in Budapest, and in the Kingdom of Serbs, Croats and Slovenes it was transferred to Belgrade. The stock company’s tasks were performed by: the stockholders’ general assembly, headquarters and the inspecting committee. The company’s railway lines were exploited i.e. administrated by the state. During the Austro-Hungarian Monarchy the company’s railway lines were exploited by the Traffic Administration of the Royal Hungarian State Railways in Zagreb, whereas after the establishment of the Traffic Administration in Pecs they came under the latter’s jurisdiction. In the Kingdom of Serb, Croats and Slovenes/Yugoslavia the company’s railway lines were exploited by the Directorate of the State Railways in Zagreb. Because of the company’s capital of 10,199.200 crowns and being solvent it can be concluded that the stock company represented a respectable and successful private vicinal railway.
