Development of High-Speed Rail in the People's Republic of China
... By 2020, China's railway network had reached 150 000 km, including a total of 30 000 km of high-speed railway, covering more than 80% of the country [1]. It represents a world-renowned achievement. ...
Transmission machinery is widely used in railway vehicles and is an important component in driving the operation of trains. Such transmission components are prone to faults under long exposure to harsh environments and complex working conditions. This affects normal operation and order, and thus it is important to ensure their safe and reliable operation. Electrical signal-based diagnosis technology has advantages of easy signal acquisition, with no need to install additional sensors, nor embedded monitoring of the object components. It has gradually become a research hotspot in the field of rail transportation diagnosis. This paper describes the fault modes of transmission machinery, takes the electrical signal-based diagnosis method as the entry point, collates and compares the existing diagnosis methods and research results in this field. It analyses their advantages and disadvantages, and finally puts forward problems for current and future research and development.
In China, local governments often build “new towns” far from the city center but close to new high-speed rail (HSR) stations. While some HSR new towns experience economic growth, others have been vacant for years and become “ghost cities.” This study explores the determinants of this heterogeneity. Using satellite imagery and online archives of government documents, we identify 180 HSR new towns. We use several datasets to measure local economic growth at a fine spatial scale. Building on the recent economic geography literature, we implement an instrumental variable strategy and a difference-in-differences approach that estimates the treatment effect with counterfactual locations to study how the creation of a new HSR station stimulates local economic growth. We find that the location and local market access are key determinants of the success of new towns. “Ghost cities” are more likely to emerge if the new stations are located too far from the existing city center or the city itself has weak market access.
Hosting more than two-thirds of the global high-speed train network, and growing at an unprecedented rate, China has become an interesting location for studying this infrastructure. In this paper, the authors begin by introducing some particularities related to the high-speed travel experience, in order to provide a general understanding of how it affects people’s perceptions of time and space. This is followed by an explanation of some peculiarities that have defined the Chinese case as unique. Grounded on theories that assert the interlaced connection between modernity and phenomenology, in this paper the authors explore the connection between the conditions that defined modernity in China and the phenomenology of travel using high-speed trains. The problematic initial approach to Chinese modernity – through the Great Leap Forward and the Cultural Revolution – impacted later decisions regarding the new infrastructure, rendering high-speed train journeys in China unique. After the end of the Cultural Revolution in 1976, when China recovered a sense of normality and togetherness, modernity was globally staged out. Two years later, China commenced the development of its high-speed rail (HSR) network and the beginning of the reform era, as part of its statements of a reframed modernity. This paper explores how the singularities of the Chinese modernity have affected the development of the High-speed train network, defining a particular phenomenology of the trip.
