Interpretation of Main Amendments of Code for the Design of Railway Lines

Code for the Design of Railway Lines is one of the professional technical standards for railway design. The decade of original standard enforcement witnesses the rapid railway development in our country. With the large-scale construction of high speed railway, a lot of new problems and new situations are encountered and also a lot of experiences are accumulated in engineering construction and operation, especially in the design, construction and operation in recent years of high speed railway, intercity railway and heavy haul railway. The amendments of the code are based on the changes in railway scientific and technological progress in recent years, on the latest achievements in the development of the technology and equipment, and on the summary of the past experiences to fully integrate the specifications for the design of high speed, inter-city, shared passenger and cargo Ⅰ and Ⅱ and heavy haul railway. The revised code fully covers the contents related to the design of rail lines. This paper expounds the basis, principles, main contents and key clauses of the amendments, so as to provide the technical personnel engaged in railway design, construction and operation with a better understanding and reference of application norms.
