Frequent situations at railway stations in Moscow occur when families with minor children due to a number of objective and subjective reasons, are in socially dangerous situations and need help. In order to solve this problem, a charity fund of social assistance to children entitled “Spread Your Wings”, together with the Moscow regional directorate of railway stations have started a new type of service: social assistance to kids which gives urgent social assistance to children and families with minor children who are at risk while on the territory of a railway station. In contradiction to the State approach, the family is treated as a whole unit, without being temporarily separated. The purpose of this article is to identify social characteristics of clients receiving emergency social assistance at railway stations in Moscow and to show the specificity of its delivery. The methods of the study consisted of standardized interviews, document analysis, frequency analysis. The authors identified and described the main groups of clients receiving emergency social assistance, and define the criteria for finding a child in a socially dangerous situation at the station. Children are at social risk in situations when their parents or other legal guardians are not able to meet their basic needs (physical and psychological), such as providing food, sleep and rest, while the children are at the railway-station.
