Fourth industrial revolution sounds largely abstraction, but we all feel the effect on our everyday life. The speed of technological breakthroughs in the past 20 years has been unprecedented in history. Moreover, they affect almost every industry in almost every country. The opportunities that connect billions of people around the world are virtually unlimited. All of these will be multiplied by the introduction of technologies such as artificial intelligence, autonomous devices, three-dimensional printing and nanotechnology in mass use. Modern digital technologies accelerate the development of rail transport in developed industrial countries, but have a significant impact on the Bulgarian railways. The purpose of the article is to outline the main trends in the development of the railway business in Bulgaria as a result of the accelerated digitization. For the purpose of the empirical study of the railway business, the methods of comparison, abstraction, generalization and classification were used.
