The aim of this paper is the study of the methods applied to financing its fixed assets by the Andalusian Railway Company (Andaluces) between 1920 and 1930. This company was the third largest among the Spanish railway companies, behind NORTH and MZA. Andaluces was formed in 1877 by a group of entrepreneurs from Malaga, the company had an area of regional activity centered in Andalusia and presented serious economic problems since the nineteen twenties which led to its confiscation in 1936. In this context of a company in crisis, we do a study of its financial situation through an accounting tool called Flow Statement Effective (EFE). We apply the indirect method, which makes it possible to obtain an approximation to the flow of activities operating, investing and financing in the company. The election of the period studied is motivated by being in an abundant stage of investments, whose origin presents some doubts about whether the company was financed with its own resources or if the provision of public capital was a majority.
