This Code is prepared with the view to unifying the technical standards of railway alignment design， and making the design meet the requirements on safety， reliability， advanced. technology， economical efficiency and applicability.This Code is applicable to the alignment design of standard-gauge high-speed railway，intercity railway，Class I and Classllmixed traffic railway，as well as heavy-haul railway. The alignment design of heavy-haul railway which also serves passenger transport shall be conducted according to the same design standards as that of mixed traffic railway， The alignment design of Class III and ClasslV railway shall be conducted according to related design standards.

This Code is prepared according to the requirements of National Railway Administration regarding establishing the railway engineering construction standard system，based on the previous edition of this Code，with the view to meeting the needs of construction and development of railway bridges，unifying the design standards，improving the design level， and ensuring the safety and quality of steel structures of railway bridges； this Code is prepared also by summarizing and absorbing the experience and scientific research results in recent years in the field of construction and operation of bridge steel structures used in China's high-speed railways，intercity railways，mixed passenger and freight railways and heavy-haul railways.In this Code， the principle of giving priority to safety is implemented， the requirements on quality safety，resources conservation and environmental protection are enhanced，the overall design is emphasized； the main design criteria of steel structures of railway bridges with different transport properties and different speed classes are rationally determined in consideration of the national situation，the economic and social development level and the environmental conditions in China，so that the scientificity and technical-economic rationality of this Code have been further improved.In recent years，a lot of new materials，new structures and new techniques in the field of railway steel bridge design have emerged in China， such as Q500q steel， all-welded panel joint，monolithic steel deck，and cable-stayed bridge and suspension bridge more than 1 000 m long，etc，and these advanced achievements and proven experience are summarized and absorbed in this Code.The Code consists of ten chapters，namely General Provisions，Terms and Symbols，Materials and Basic Allowable Stresses，Calculation of Internal Force，Calculation Length，Slenderness Ratio and Cross Section of Members，Connection of Components，Deck System and Connecting System，Steel Plate Girder，Steel Truss Girder，and Bearing.Five appendixes are provided.

This Code is prepared on the basis of comprehensively summarizing the practical experiences and scientific achievements on railway station and terminal design， construction and operation of China's high-speed railway，intercity railway，mixed traffic railway，and heavy-haul railway.This Code implements the national development concept of “innovation， coordination，green，openness and sharing”， and conforms to the policies and regulations on integrated traffic andtransportation development， on natural ecology and environment protection， on land and energysaving，etc.In this Code， safety priority principle is highly strengthened； the idea of systematic design for stations and terminals，and the idea of capacity coordination between lines and stations are highlighted.The design principles and design parameters for stations and terminals are reasonably determined based on national conditions， economic and social development level，transportation demands and environment conditions，which greatly improves the scientificity as well as the technical and economic reasonability of this Code.This Code consists of sixteen chapters： General Provisions； Terms； Basic Requirements；Terminal； Marshalling Station； District Station； Intermediate Station and Combination & Disassembly Station； Passing Station and Overtaking Station； Passenger Station， Passenger Facilities and Equipment and Passenger Car Depot （Shed）； Railway Logistics Center； Hump；Industrial Station and Harbour Station； Border Station； Freight Collection Station and Freight Distribution Station； Earthworks and Drainage of Railway Station and Yard； Station Tracks.Also there are two Appendixes.
