ABSTRACT
From the standpoint of modern locomotives, their mechanical systems can be seen as a set of unied design elements consisting of the following main assemblies and components:
• The locomotive car body with a main structural frame that transmits traction and dynamic forces, and on which are located the main power plant units and various units that undertake the overall monitoring and management of the locomotive’s performance and movement. These include the traction transmission control, braking, cooling, ventilation, oil, water and re protection systems, plus auxiliary equipment and safety devices. This leads to the division of the body and underbody spaces into the relevant areas and compartments needed for the protection of the equipment and the locomotive crew from the effects of various hazards arising from the operation of the locomotive. The layout is designed to create a safe and comfortable working environment for the crew and locomotive maintainers.
