1. Understanding the basic rail vehicles assemblies, 2. Acquiring the knowledge needed for understanding of functioning of the basic structural assemblies, 3. Training for the application of acquired knowledge for solving practical engineering problems, especially in the field of maintenance of the railway vehicles.
After completing the course, students should be able to: 1. Explain the functional and structural differences between basic types of rolling stock. 2. Explain the tasks and functioning of the main assemblies of the rail vehicles. 3. Identify actions required to resolve typical failures in operation and in the maintenance of the rail vehicles. 4. Apply appropriate regulations and standards in the design and maintenance of the railway vehicles. 5. Apply basic computer tools for construction and calculation of the simple assemblies of the rail vehicles.
