The turnouts with rail type are meticulously categorized into various classes: 8 kg/m, 12 kg/m, 15 kg/m, 18 kg/m, 22 kg/m, 24 kg/m, 30 kg/m, 38 kg/m, 43 kg/m, 50 kg/m, 60 kg/m. Additionally, they are classified by number types: No. 2, No. 3, No. 4, No. 5, No. 6, No. 7, No. 8, No. 9, No. 12, etc. These turnouts further diversify into single switch, symmetrical switch, triple switch, compound switch, cross-crossing switch, and cross-crossing combination switch, among others. A turnout is an essential piece of line-connecting apparatus, enabling locomotives and vehicles to transition seamlessly from one track to another. Predominantly, these turnouts are extensively deployed at stations and marshalling yards, significantly enhancing the rail system's efficiency and capacity. Strategic placement of turnouts ensures that even a single track can maximize its usage potential. By integrating a turnout with a fork longer than the train itself, smooth train transitions are achievable, thereby bolstering the overall functionality and adaptability of the railway network.
