EN Standard Rail Dimensions
EN rail sizes are known for their precision and reliability in railway construction. Measurements like rail head, web, base, and weight per meter classify these sizes. For instance, the 46e1 rail size weighs 46.17 kg/m and has a 65-mm head, 145-mm web, and 125-mm base. The 46e4 rail size weighs 46.9 kg/m and has a 135 mm rail base but the same rail head and web dimensions. These variations allow engineers to choose the best rail size for certain applications.
Dimensions and weight adjust to greater loads and higher speeds as rail sizes grow. The 60e1 rail size, with a 72-mm head, 172-mm web, and 150-mm base, weights 60.21 kg/m. However, the 54e1 rail size. By understanding these criteria, professionals can choose the proper rail size to meet rail size standards and operate well.
