The paper introduces the structural features,manufacturing difficulties,manufacturing craft for key spare parts,and quality control measures of the double crossover of No. 12 ballastless turnout with 5 m distance on 60 kg/m steel rails of some passenger special railway,points out the crossover can meet the demands for turn-round tracks on express railways or ballastless rails of intercity railways,and indicates the alloy steel composite structures can be adopted for single-open,acute-angle,and obtuse-angle frog,so it is suitable for the cross-section iointless track and it can improve the transportation efficiency.
