Abstract: Objective: Turnout is one of the key components in suspension monorail transit system. To reduce the difficulty in turnout type selection and process layout, and to ensure optimal turnout solutions for different engineering scenarios, it is necessary to study the above issues. Method: Based on a comprehensive review of turnout type application status in multiple suspension monorail lines in China and abroad, the principles, structural compositions, and main characteristics of translation beam turnout, laddertype core rail turnout, inverted Tshaped core rail turnout, and articulated turnout are expounded. The main performance and indicators of each turnout type are compared. Considering the requirements for turnouts in different engineering scenarios such as station entry/exit lines, single crossover lines, emergency parking lines, depot entry/exit lines, and depot parking lines, factors such as turnout transition time, smoothness, site area, maturity, and investment for different suspension monorail turnout types are taken into account. Consequently, the optimal turnout type and process layout for the above lines are proposed. Result & Conclusion: For station entry/exit lines, the inverted Tshaped core rail turnout should be preferentially adopted; and the same turnout for single crossover lines; for emergency parking lines, a combination of inverted Tshaped core rail turnout and translation beam turnout; for depot entry/exist lines, the inverted Tshaped core rail turnout; for depot parking lines, the translation beam turnouts at initial stage, and the articulated turnout once the products mature.
