The turnouts, categorized by rail type, span a range from 8 kg/m to 60 kg/m, 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 are divided by specifications into: No. 2, No. 3, No. 4, No. 5, No. 6, No. 7, No. 8, No. 9, and No. 12, among others. Turnouts can be further classified into single switch, symmetrical switch, triple switch, compound switch, cross-crossing switch, and cross-crossing combination switch. A turnout is an essential line-connecting device, enabling locomotives and vehicles to transition smoothly from one track to another. These turnouts are predominantly installed in large quantities at stations and marshalling yards, significantly boosting the efficiency and capacity of the rail system. Strategically placed turnouts allow even a single track to maximize its utility. By integrating a turnout with a fork longer than the train itself, the seamless switching of trains becomes feasible, enhancing the overall functionality and flexibility of the railway network.
