Reversible gates enable the creation of fault tolerant digital devices. The application of these gates allows safe control systems to be realized. At present, control systems based on relays are being replaced by systems based on computer technology. This technology allows the implementation of safe systems. Because this system is composed of many elements, it is very difficult to obtain a high safety level for it. The application of reversible logic in the synthesis of digital systems constitutes an alternative approach. The paper presents reversible gates along with examples of their usage in the synthesis of digital systems. The main advantage of reversible logic is the possibility of synthesis of self testing and fault tolerant circuits. The application of circuits based on reversible logic allows safe control systems to be developed. The paper also presents a proposal for the application of reversible logic in simple control systems. Keywords: reversible logic, railway traffic control, safety
