The earliest railways in China，due to introductions from the UK，France，Germany，Japan，Russia，the United States and other countries with different railway standards and equipment，was ridiculed as “International Railway Exhibition.” Since the founding of the People’s Republic of China，especially since the beginning of the twenty-first century，China has begun to move towards independent innovation through importing，digesting and absorbing. From the Qinghai-Tibet Railway on the western plateau to the eastern coast railway，from the Harbin-Dalian High-speed Railway in the northern cold area to the Beijing-Guangzhou High-speed Railway with the longest operating mileage in the world，problems that had been existing for centuries have been overcome one after another and world records have been frequently broken. From the establishment of the National Laboratory for Rail Transportation （Preparation） by Southwest Jiaotong University in 2006 to the establishment of the “National High-speed Train Technology Innovation Center” in 2016—the first national technology innovation center co-founded by China Railway Rolling Stock Corporation and Qingdao City，the rail transit research strength and technological innovation of China are growing rapidly. China’s rail transit has become a microcosm of national development. From blank and lagging behind to corner overtaking，China repeatedly refreshes the “China speed” and demonstrates its national strength and national rejuvenation.
