Purpose: The development of machine-friendly calculation algorithm of maximum average (reduced) slope for to define minimal norms for securing cars, groups of cars or train stocks that’re left on station railways without locomotives. Methods: The set task solving was held by making up the succession of mathematical and logical actions. Mathematical expressions describe flattening of track longitudinal profile, i.e. the calculation of reduced slope. Logical actions describe limitations at pursuing the calculations. Results: Calculation algorithm of reduced slope has been made up which takes into account the provisions of Instructions on Train Motion and Shunting Work on Railway Transport of the Russian Federation. Practical significance: The developed algorithm allows to pursue the calculation of reduced slope at the least favorable conditions of the placement of cars, group of cars and stocks of trains in the frames of effective length of station tracks that corresponds to provision conditions for rolling stock securing from leaving. The pursued research allows to develop program for defining minimal norms for securing cars, groups of cars and stocks of trains that’re left on station railways without locomotives, in full accordance with Instructions on Train Motion and Shunting Work on Railway Transport of the Russian Federation.
