A simplified schematic diagram of a high-speed electric multiple unit. The diagram shows the overall structure of the train, including the main body and the bogies. The main body is connected to the bogies by suspension systems, which include springs and dampers. Each bogie has two wheelsets, and the suspension systems are depicted as vertical lines with zigzag lines representing springs and small boxes representing dampers. The diagram illustrates how the main body is supported by the bogies through these suspension systems.
