The turnouts are available in various rail types, including 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, and 60 kg/m. Additionally, they come in several numbered specifications: No. 2, No. 3, No. 4, No. 5, No. 6, No. 7, No. 8, No. 9, and No. 12. These turnouts can be categorized into single switches, symmetrical switches, triple switches, compound switches, cross-crossing switches, and cross-crossing combination switches. A turnout is an essential piece of line-connecting equipment that allows locomotives and vehicles to transition smoothly from one track to another. These turnouts are predominantly installed in significant numbers at stations and marshalling yards, thereby amplifying the efficiency and capacity of the entire rail system. With the strategic placement of turnouts, even a single track can be fully utilized to its potential. By incorporating a turnout with a fork longer than the train itself, it becomes possible to switch trains seamlessly, thus greatly enhancing the overall functionality and flexibility of the railway network.
