As one of the country's most important transportation infrastructure organizations, RAI plays a vital role in facilitating the safe and efficient movement of passengers and freight while supporting the nation’s economic and industrial growth. Operating an extensive rail network across the country, RAI manages railway lines, stations, operational centers, and specialized infrastructure through a highly skilled workforce. The organization serves as a key contributor to sustainable transportation by improving logistics efficiency, reducing energy consumption, strengthening industrial supply chains, and expanding regional and international transit capabilities. Safety, operational excellence, workforce development, and the adoption of innovative technologies are among RAI’s core strategic priorities. Through continuous investment in modern railway systems and standardized operational practices, the organization remains committed to enhancing the quality, reliability, and sustainability of rail transportation throughout Iran.

Virtual Reality-Based Simulation System 
Thermite Welding Operations Training for Railway Tracks
The purpose of developing this system is to enhance training quality and improve safety in thermite welding operations on railway tracks through the use of Virtual Reality (VR) technology. By providing an immersive and interactive training environment, the system enables technicians and welders to practice the complete thermite welding process without requiring real equipment, allowing them to develop practical skills in a safe and risk-free setting.
The simulator features realistic three-dimensional models of the thermite welding process and all associated equipment. Users can enter the virtual environment, select the desired operation, and complete each stage of the welding procedure step by step, closely replicating real-world working conditions.
The system includes multiple training scenarios, including thermite welding using single-use crucibles, thermite welding using reusable crucibles, long welded rail (LWR) welding, and broken weld repair. Throughout these scenarios, trainees become familiar with the required equipment, operational procedures, and safety requirements while practicing and evaluating their performance in different training conditions.
In addition, the system incorporates a comprehensive performance assessment module that monitors each user's execution of the training procedures. By providing detailed feedback on strengths and areas for improvement, the simulator supports continuous skill development, enhances operational proficiency, and helps ensure greater safety and consistency in railway thermite welding operations.
