TB 10098-2017 is the English-translated version of 铁路线路设计规范.

TB 10098-2017 — 1.0.1 This Code is prepared with the view to unifying the technical standards of railway alignment safety, reliability, advanced technology, design, and making the design meet the requirements economical efficiency and applicability.

1.0.2 This Code is applicable to the alignment design of standard-gauge high-speed railway, intercity-railway, Class I and Class II mixed 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 design standards as that of mixed traffic railway.

The alignment design of Class HI and Class IV railway shall be conducted according to related design standards.

1.0, 3 In the process of railway alignment design, green and harmonious development concept shall be implemented , requirement for modern comprehensive transportation development shall be carried out , project demand , railway network planning and comprehensive transportation planning shall be thoroughly studied, project functional orientation shall be correctly grasped, construction scheme shall be scientifically demonstrated , main technical standard and railway alignment shall be reasonably selected, and railway route plan and profile shall be systematically optimized.

1.0.4 The design year for railway line shall be classified into short term and long term. The short term refers to the 10th year after being put into operation, and the long term refers to the 20th year after being put into operation.

The predicted traffic volume shall be used for both the short term and long term traffic volumes. The design for the scales of railway infrastructures as well as equipment and buildings shall comply with following provisions.

1 The infrastructures under railway tracks as well as the buildings and equipment which are hard to be renovated or expanded shall be designed according to long term traffic volumes and traffic types.

2 The buildings and equipment which are easy to be renovated or expanded should be designed according to short term traffic volumes and traffic types, while long-term development conditions shall be reserved.

3 The operation equipment such as EMUs and locomotives and cars, whose allocation decrease with the change of transport demand, may be designed according to the predicted traffic volumes of the 5th year after being put into operation.

1.0.5 The performance coefficient of section carrying capacity shall be taken into account for the carrying capacity of high-speed railway and intercity railway.

A certain section carrying capacity shall well as heavy-haul railway. The reserved section carrying capacity for single track railway and double-track railway shall adopt 20% and 15% respectively after the deduction of comprehensive maintenance window, and the fluctuation of passenger and freight traffic volume shall be taken into account.

1.0.6 Far-future annual transport capacity shall be calculated in railway alignment design. 1.0.7 The design philosophy of people first shall be consistently carried out in railway alignment design, and the principles of safety design and risk management shall be implemented in the whole design process.

1.0.8 Railway alignment design shall adhere to the ideas of natural ecology and environment protection as.
