CR Fuxing EMU Series
In 1990s, China began to organize research and
development of high-speed EMU series and received notable results such as
Xianfeng and China Star EMUs, which were designed and produced independently
and put into use after many trials. Since 2004, after introducing and absorbing
advanced foreign manufacturing technologies of EMU, CRH train series including
CRH1, CRH2, CRH3, CRH5 and CRH380 were put into production and operation in
batch.

Study on Development Strategy of China’s Intelligent High-Speed Railway
The paper analyzes the development trends of digitization and intelligence for global
railways, as well as the construction situation, the achievements of IT
application and the challenges of China high-speed railway (HSR) and puts
forward the connotation of intelligent HSR and its four components, namely, the
brain platform, intelligent construction, intelligent equipment and intelligent
operation. Going forward, the paper carries out the blueprint design of
intelligent HSR based on cyber-physical systems (CPS) and proposes a six-dimensional
correlation analysis method. It then applies it in the strategic planning of
intelligent HSR, determining the goal of development for China HSR in the three
stages of innovation demonstration, accelerated breakthrough and comprehensive
improvement from 2018 to 2035.

Study on the Intelligent High-speed Railway System Framework
With the rapid development of high-speed railway and
intelligent technologies, the construction of intelligent high-speed railway
has been started in China in an all-round way. Due to the fact that intelligent
high-speed railway involves complex Cyber-Physical Systems (CPS) engineering,
top-level design is needed to set a path for the its construction
and future development. Based on the analysis of the design methods and
research ideas of intelligent system frameworks both at home and abroad, and the
connotation and characteristics of intelligent high-speed railway system in
China, the framework of intelligent high-speed railway system is studied. Concepts
of service architecture, functional architecture, logical architecture, and
physical architecture are put forward. Studies are also carried out on the connotation and composition of the Brain of intelligent
high-speed railway.

Application of Large-capacity BPT System on Neutral Sections on Long Slope
The thesis is based on a railway project, setting
neutral sections on a long slope with gradient of 30‰ in Xiangjiang Tunnel on the
Changsha-Zhuzhou-Xiangtan Intercity Railway.
Difficult technical problems in the project call for the application of
large-capacity current converting control technology, thus BPT system is in
operation to enable catenary to provide uninterrupted power supply when the
train passes neutral sections. The thesis then explores its theoretical
foundation, and proposes to work out complete technologies and application
plan. The thesis also finds that after five years of R&D, test, appraisal
and application in the project, BPT system is proven to be advanced in high
level of automation, good compatibility with train and catenary, and high
reliability in operation. BPT System has effectively solved technical
difficulties concerning neutral sections, and offered an optimized solution for
25kV AC traction mode getting electricity from the public power grid. The
successful application of the system also shows that it is a reliable technical
solution when applied in breaking phase and in complex railway projects.

Practice of Exploring the Configuration of an Intelligent Traffic Control Center
Most of the current
mainstream study on Smart Enterprises focuses on the intelligence of
information technology. This paper broadens the perspectives to the
relationship between information technology and traffic control center's core
business, organizational reform and management innovation, and discusses the
background of configuring an intelligent traffic control center. Based on the
theory of Intelligent Enterprise and the characteristics of traffic control
centers, it expounds the contents, characteristics and composition of
intelligent traffic control center activities, mainly introducing the practice
of the Traffic control center of the Beijing Administration with its efforts to
actively explore the main methods and preliminary results of configuring an
intelligent traffic control center.

Study on the Health Monitoring Index of Long-span High Speed Railway Bridge Based on Service Condition
The technical standard system of high speed railway
(HSR) infrastructure ought to cover the full life cycle of the infrastructure,
including the standards of design, acceptance and operation. For long-span
bridges, environmental factors like wind, temperature, creep, settlement which
have a marked influence on structural performance should be taken into
consideration in design and operation. Various loads are in adverse situation
in the stage of design, and it is required that structures should meet strength
demand in combined action, while deformation limits are prescribed in
accordance with various loads, and the stiffness requirements of the structure arer
not put forward. Therefore, the design standards cannot be adopted directly in
the operation stage of the structure. The paper carries out a comparative study
on the adaptation of radius of curvature, wave length amplitude and chord
length to the deformation control of long-span bridges, and proposes the
analysis process of health monitoring index limit by taking a deck arch bridge
as example, which can be used in static deformation control in operation stage
for different bridge types and spans.

Study on the Technical Standards of Jakarta-Bandung High Speed Railway
In combination with
the Jakarta-Bandung high-speed railway (HSR) project in Indonesia, the paper
carries out the adaptability study on the technical standards of China’s HSR
for “going global”. It analyzes the influence factors in selecting the
technical standards for the project from the perspectives of natural
conditions, social factors and technical levels, conducts the adaptability
study on the major technical standards as well as the professional technical
standards covering lines, track, geology, subgrade, bridges and tunnels and
puts forward proposals for the technical standards adapting to the conditions
of the project. The achievements of the study provide support for the
construction of the project and offer references for further optimization and
improvement of the technical standards of China’s HSR as well as for other “going
global” projects.

Revisions of Regulations on Railway Technical Management
The Regulations on
Railway Technical Management of CHINA RAILWAY are the basic technical
regulation of national railway. Since their release and implementation in 2014,
the provisions that do not adapt to the requirements of transportation and production
need to be revised and improved to match the upgrading of railway technical
equipment, optimization of transport organization and changes in relevant
national laws, regulations and standards. The paper puts forward the basic
principles of revision, determines the background, reasons, bases and contents
of revision for the main provisions and thus mainly solves the a series of key
technical problems covering external locking device for turnout, distance
between the inner edge of power line pole and the center line of track, train
sign display mode, train classification and operation class sequence,
locomotive return across traction section, speed restriction of passenger train
with its cut-out-cock of its automatic brake and speed restriction of EMU trains
when passing small radius curve, providing technical support for the assurance
of transport safety and efficiency of railways.
