When the railway grade cannot be delineated according to Table 1.0.6 due to the nature of the industrial enterprise, coordination with road network transportation or other reasons, it should be clearly stated in the design task book, or arguments should be put forward in the preliminary design and determined after approval.
Industrial enterprise railways with an operating period of less than ten years are not divided into grades and are designed in accordance with the provisions of this specification on railways with limited use.
When the freight volume passing through each section of the industrial enterprise railway is different, it can be considered to design according to the grade railway standards corresponding to the freight volume of each section, but it should meet the needs of traction constants determined according to the transportation organization.
For industrial enterprise railways operated by shunting, their technical standards can be selected according to their functions or lengths:
1. The connecting lines from the connection point to the enterprise station (yard) and between the enterprise stations (yards); the industrial enterprise traffic lines; and the connecting lines from the connection point or the branch point to the outside of the operation field (excluding the connected operation or parking line segment), whose length is more than 2km, should be designed as the connecting lines for shunting operation. 3. The connecting lines from the connection point or the branch point to the outside of the operation field (excluding the connected operation or parking line segment), whose length is 2km or less, and other connecting lines, can be designed as connecting lines.
Article 1.0.7 The maximum operating speed of trains on various levels of railways shall not exceed the following values:
