Common rail models
Rail is an important part of railway, used to carry trains and ensure the safety and smoothness of railway transportation. According to different usage scenarios and load requirements, each type of rail has its specific standard size and performance requirements. This article will introduce the sizes and standards of various types of rails to help you better understand and choose the right rail.
1. 50kg/m rail
50kg/m rail is a standard rail for Chinese railways, mainly suitable for passenger and freight dual-use lines and heavy-duty railways. Its standard length is 25m, height is 162mm, bottom width is 150mm, rail head width is 50mm, rail waist thickness is 35mm, and rail body length is 12.5m. 50kg/m rail has strong bearing capacity and is suitable for high-speed trains and freight transportation.
2. 60kg/m rail
60kg/m rail is suitable for passenger, freight and heavy-duty railway lines, and is also suitable for high-speed railways, especially in heavy-duty sections. Its standard length is 25m, height is 176mm, bottom width is 152mm, rail head width is 60mm, rail waist thickness is 38mm,
and rail body length is 12.5m. 60kg/m rail has strong load-bearing capacity and is suitable for high-speed trains and freight.
3. 75kg/m rail
75kg/m rail is suitable for heavy-duty and high-speed railway lines, and its load-bearing capacity is stronger than 50kg/m and 60kg/m rails. Its standard length is 25m, height is 192mm, bottom width is 150mm, rail head width is 75mm, rail waist thickness is 44mm, and rail body length is 12.5m.
4. 43kg/m rail
43kg/m rail is suitable for special railways for industrial and mining enterprises, road ferries, docks and narrow-gauge balance rails, and is the standard rail for narrow-gauge railway lines. Its standard length is 6m, 9m and 12m, height is 114mm, bottom width is 107mm, rail head width is 43mm, rail waist thickness is 14.1mm, and rail body length is 6m.
5. 60R rail
60R rail is suitable for internationally used narrow-gauge lines. Its standard length is 6.09m, 7.32m, 8.55m or 9.14m, height is 146mm, bottom width is 146mm, rail head width is 60mm, rail waist thickness is 30.2mm, and rail body length is 6.09m.
The above is a detailed introduction to the sizes of various types of rails. Different types of rails have their specific standard sizes and scope of use. The selection of rails should be based on actual needs. In railway maintenance and construction, the correct use of suitable rails is the basis for ensuring the safety and efficiency of railway transportation.
