This article is focused on description of four ways of tracking control on the modeling yard. The yard is situated in the laboratory of Department of control systems and instrumentation. Control system was continuously developed by the help of students. First step was connecting the particular model´s objects to input/output devices of the PLC control system and creating the basic programs. Next steps were design and creating of the hand control panel, creating of display views in InTouch software, design and creating of digital control panel and digitalization of locomotives.
