U radu autor na temelju arhivskih izvora, a s aspekta povijesti institucija, obrađuje ustroj i djelovanje Dioničarskoga društva Lonjskopoljske željeznice u periodu Austro-Ugarske Monarhije. Sjedište Društva, kao i većine vicinalnih željeznica, bilo je u Budimpešti. Poslove Dioničarskoga društva obavljali su glavna skupština dioničara, ravnateljstvo i nadzorni odbor. Pruge Društva bile su sljedeće: Dugo Selo – Novska i Banova Jaruga – Pakrac. Te privatne pruge bile su u državnoj eksploataciji, odnosno upravi. U Austro-Ugarskoj Monarhiji pruge Društva potpadale su pod nadležnost Poslovne uprave Kraljevskih ugarskih državnih željeznica u Zagrebu. Društvo je 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 The Lonjsko Polje Railway Stock Company during the Austro-Hungarian Monarchy. Like the majority of other vicinal railways, the company had its headquarters in Budapest. The stock company was founded on 15 June 1896. The stock company’s tasks were performed by: the stockholders’ general assembly, headquarters and the inspecting committee. The company’s railway lines were: Dugo Selo-Novska and Banova Jaruga-Pakrac. They were put into traffic on 29 November 1897. These private railway lines were exploited i.e. administrated by the state. During the Austro-Hungarian Monarchy the company’s railway lines came under the jurisdiction of the Traffic Administration of the Royal Hungarian State Railways in Zagreb. The Novska-Dugo Selo-Zagreb railway track was approximately 12.5 km shorter than Novska-Sisak-Zagreb, whose Sisak-Zagreb-Savski Marof (Zidani Most) branch was owned by the Southern Railway Society, the biggest and the most powerful railway stock company in the Monarchy. That by default made them competitors. During its construction it was decided to create a transit railway line from the former for the transitional traffic to the detriment of the Southern Railways. By analysing the published information on the business activity of the Lonjsko Polje Railway in the Austro-Hungarian Monarchy and by comparing it with other Croatian-Slavonian vicinal railways, bearing in mind its stock capital of 9.940,000 krone and its operating in the black, it can be concluded that the stock company was a respectable and successful private vicinal railway.
