Intercity railways are an important link to the construction of a comprehensive urban transportation system,and its characteristics of"high density,small formation,and public transportation"put forward requirements for turnouts with high smoothness and high reliability.Due to the large amount and wide application range of 60 kg/m rail No.12 movable-point frog simple turnout and matched scissors crossings in the industry of intercity railway,this article conducts research on the design of a 60 kg/m rail No.12 movable-point frog simple turnout and matched scissors crossings or intercity railways.The main contents include the plane alignment design of the simple turnout,5.0 m scissors crossing plane alignment design,and homogenization design of the track stiffness in the turnout area.Mature technology should be adopted as far as possible in the design to enhance the versatility of the components,and facilitate maintenance and operation maintenance management.This article should compensate for the lack type of intercity railway turnout products,develop a series of 60 kg/m rail No.12 turnout products suitable for operating speeds of 200 km/h and below,that may provide reference and inspiration for the selection and design of future intercity railway turnouts.
