Automatic systems are employed in all areas of human's activity: industry, ecology, economics, biology, transport; methodologies of feedback control, signal processing and pattern recognition.
The characteristics of automatic systems are as follows: functional interaction between mechanical, electronic and information technologies, spatial integration of subsystems in one physical unit, intelligent control functions of the automatic system, flexibility, the ease of automatic products modification to fit changing requirements and situations.

Means of training for this speciality are expected to be different forms of study arrangement, selection of methods and skills of teaching intended to increase efficiency of the educational process.

To perform the analysis and synthesis of automatic control systems based on the requirements, a model of the stand controlled by the controller of the railroad has been developed.

The control is performed by transfer of a task from SCADA to PLC. An infrared transmitter connected to it sends the appropriate signals to the receiving sensors built into the locomotive. The controller also changes-over railway switches and semaphores.

Railroads are logically loop-like to be able to prescribe the train a route through the randomly selected stations. The control system must find the optimal route structure. Here it is possible to develop and implement numerous algorithms for motion using the theory of terminal automatic device.

In addition to the trains movement, there are possibilities to program the rotation of the mills, lighting of individual buildings and industrial facilities, as well as the whole streets and industrial areas, lighting, beacon etc.

Extensive programming features two-wire data transfer protocol (on rails) for these purposes the existing industry (AS-i) and special (DCC) protocols.
It is used for pupils and students as a visual aid, showing an attractive application of automation, electronic control and programming in reality. Specially developed object is intended to increase efficiency of the educational process.
