Introduction
One of the priority tasks of the higher technical education system is to prepare specialists for professional activities. Currently, there is an active expansion of the use of modern teaching tools in the educational process, operating on the basis of digital technologies, implementing the features of artificial intelligence systems and forming high-quality training of railway transport specialists. The improvement of scientific and technical achievements in the field of high-tech equipment and software has led to the development of technologies that provide modeling, simulation, simulation, visualization, in which three-dimensional modeling is actively used in the training of future specialists, allowing you to simulate existing and abstract models in detail and visualize them in the environment of real-world objects. Changes in education related to the need to use digital technologies [1] determine the feasibility of developing new software and hardware tools and teaching methods, including the development of requirements and conditions for the use of high-tech simulators and the implementation of psychological, pedagogical, educational and methodological support in the conditions of ensuring the safety of students when using high-tech simulators with virtual and augmented reality technologies.
Materials and Methods. The research is carried out on the basis of theoretical methods.
Results and Discussion. Under the concept of high-tech simulators, we will represent complex software-adapted systems that include elements of simulation and simulation of the objects being studied, physical or screen models, the implementation of which provides simultaneous perception of objects, processes, scenes of real reality and virtual reality by the user [2].
The system of training students of transport universities with the use of simulators should provide the tasks of forming practical skills of the future specialty in accordance with the types of professional activity and qualification characteristics. The technical design of the simulators used in the training system, as well as their software, must exactly correspond to the new technical means, have the same controls and assume the possibility of modernization, depending on the changes made to the design of the technical means.
This leads to the need to develop a set of conditions, both for the simulators themselves, which implement the features of artificial intelligence systems, and for the organization of work with simulators in the educational process [3].
The conditions for the use of simulators in the educational process that implement the features of artificial intelligence systems can be structurally divided into: -conditions for the organization of work on simulators; -conditions for the implementation of the activity approach in training on simulators; -conditions of information security of software products during training on simulators; -conditions for leveling possible negative consequences for the health of the student when using simulators; -content and pedagogical conditions for the use of simulators in the educational process.

Duration of stay in the visual environment
Determine the permissible working time on the simulator should take into account the type of simulator used, the types of professional activity and the qualification characteristics of the future professional activity of the specialist. Choose a specific type of simulator should take into account the methodological methods of training used and the possibilities of technological and technical implementation of simulators. Taking into account the methodological method of training and in accordance with the type of future professional activity of the specialist, the permissible working time on the simulator must be determined for training: on simulators of future employees of the locomotive economy; future employees of the dispatching apparatus and personnel of the transportation service; future employees of the track infrastructure; future employees of the automation and telemechanics economy; future employees of the passenger economy; future employees of the freight economy.
