U radu autori s aspekta povijesti institucija obrađuju ustroj i djelovanje Dioničarskog društva mjesne željeznice Vinkovci-Županja-Savska obala u vremenskom periodu od godine 1900., kada je društvo osnovano, pa sve do godine 1906., kada je zajedno s Dioničarskim društvom vicinalne željeznice Osijek-Đakovo-Vrpolje udruženo u novo društvo pod nazivom Dioničarsko društvo sjedinjenih podravsko-posavskih vicinalnih željeznica. Sjedište društva, kao i kod većine vicinalnih željeznica, bilo je u Budimpešti. Željeznička pruga Vinkovci-Županja-Savska obala bila je u vlasništvu društva, ali u državnoj eksploataciji, odnosno upravi. Poslove dioničarskog društva obavljali su glavna skupština dioničara, ravnateljstvo i nadzorni odbor. Iako je društvo poslovalo s financijskim dobitkom, po eksploatacijskim i financijskim pokazateljima bilo je među slabijim vicinalnim željeznicama na prostoru Kraljevina Hrvatske i Slavonije. Nakon udruživanja, novoosnovano društvo predstavljalo je jednu od rentabilnijih privatnih vicinalnih željeznica na tome prostoru. In the paper the authors outlines from the aspect of the history of institutions the structure and the activity of the Vinkovci-Županja-Savska obala Local Railway Ltd. in the timeframe from its establishment in 1900 to 1906, when together with the Osijek-Đakovo-Vrpolje Vicinal Railway Ltd. was merged into a new stock company entitled The United Podravina-Posavina Vicinal Railways Ltd. As with most vicinal railways, the company’s headquarters was in Budapest. The stock company’s tasks were performed by: the stockholders’ general assembly, headquarters and the inspecting committee. The Vinkovci-Županja-Savska obala railway line was owned by the stock company, but it was exploited i.e. managed by the state. It was put in service on 30 September 1901. One of its main goals was to dominate the Bosnian trade and transfer its products to a Croatian market. Apart from that, various agricultural goods cultivated in the fertile Slavonian area where the aforementioned railway lines went were shipped, as well as timber from rich old oak woods anticipated to be harvested. Even though the company was financially solvent, according to its exploiting and financial indicators it ranked among the weaker vicinal railways in the Kingdom of Croatia and Slavonia. After the merger the newly established stock company was one of the more important, more successful and more profitable vicinal railways in that area.
