The UIC classification is a system used to categorize railway vehicles based on their design and function. Developed by the International Union of Railways, it helps standardize the identification of different types of rolling stock, such as passenger cars, freight wagons, and locomotives. Each vehicle is assigned a unique code that reflects its characteristics, making it easier for operators and manufacturers to communicate and manage their fleets. This classification system is essential for ensuring safety and interoperability across different railway networks. By using the UIC classification, rail operators can efficiently share information about vehicles, streamline maintenance processes, and enhance overall operational efficiency.
