The article discusses the possibility of creating effective geoinformation technologies to improve the operation of JSC «Russian Railways». The need for them is due to the huge scale of the territories occupied by the railway infrastructure, and the specifics of work activities that are associated with the organization of the transportation process. It is proposed to follow five principles when creating a unified railway GEODATA database: the use of a single coordinate base, the uniqueness of each object and the use of geographical coordinates as the primary key, the definition of a generalized graph of the railway network using a digital path model, the use of existing geoinformation resources, continuous updating and updating of information.
