This paper introduces the mechatronic system – a mining locomotive for underground transport. It is presented as a mechatronic system that makes it possible to implement an integrated approach to integration of heterogeneous elements. Discussed are the electrical drive, measuring subsystem, control subsystem, transmission of data concerning the locomotive state. A system for reading the location of each locomotive is proposed that is essential for preventing accidents. Due to severe operating conditions it is necessary to receive updated information about the state and the location of the locomotive. The information system allows for keeping statistical data of all accident and emergency situations. The aim is to extend the service life of the locomotive, to reduce emergency repairs and avoid accidents.
