High-speed railway (HS) in China has undergone rapid development and expansion, ever since the very first 350 km/h high speed rail (HS) -Beijing-Tianjin Intercity HSR-initiated its operations on August 1, 2008. After years of research and development, HR is now renowned for its high-speed technology, safety & reliability, punctuality, comfortability, and environment friendly attributes. The advent of HR technology has transformed the development of rail transport in China while massively improving the connectivity thus elevating the life quality of billions. HSR is now known as a striking brand showcasing the image of a modernized and advanced China. Regardless of China late accession to the HSR development, it is still perhaps known to be World's No.1 in development speed, construction scale and carrying capacity. By the end of 2016, the total operational route length of HRs in China had reached 22,000km and an operational speed of at least 300 km/h for trains running on Beijing-Tianjin, Beijing-Shanghai, Beijing-GuangZhou; it is evident that China is global industry leader in HSR technology. HSR technology is extremely complex with the integration of numerous advanced technology components. The track serves as the foundation of HSR, extends to whichever direction the train heading towards. The traction power system generates large amount of power for high speed acceleration. The rolling stock system is equipped with a "scud" that transport passengers in a safe and fast manner. The passenger service system provides convenience in ticketing and boarding. Lastly, the control system plays a crucial role analogous to the central nervous system" in controlling all components with a coherent command. Have you ever wondered how subsystems communicate with one another? What high-techs are applied in the HSR? How are safety and punctuality ensured in HSR operations? The following chapters in this book unravels the truths and secrets to the most advanced HSR technology in the world.
