Robotization of technological processes in rail transport is a priority area of scientific and technical policy for Russian Railways. One of the technological processes being prioritized for robotization is train break-up from hump marshalling yards, primarily due to the need to increase station processing capacity and reduce workplace injury rates. The objective of this study is to determine the state of the art and identify development trends for robotic systems used in train break-up from hump operations. The research methodology involved analysis of scientific literature and patent information. As a result of this study, quantitative characteristics of publication activity in this technological area were determined, and materials from scientific and patent documents were reviewed and systematized. During material processing, it was established that solutions predominantly utilize either: two independent mobile platforms or two manipulators mounted on a single mobile platform carriage frame. These configurations are employed to enable parallel break-up of two trains from the hump and to improve the reliability of railcar cut formation under challenging conditions. A significant limitation in developing robotic systems for train break-up from hump operations is the uneven lengths of railcar cuts. Additionally, integration with external information and control systems is of critical importance. The practical significance of the obtained results lies in identifying development trends for robotic automation of train break-up processes from hump operations. These findings can be utilized in future development of promising robotic system architectures that will enhance marshalling yard processing capacity and operational reserves through close integration with external information and control systems
