Abstract: Currently, China has relatively few medium-low speed maglev transit construction projects, causing relative lack of design experience, and difficulty in cost control through design process. For medium-low speed maglev transit project, how to meet project function demands with optimal cost is an industry-wide challenge. Based on a medium-low speed maglev transit project in China, the main influencing factors of cost control in the project are comprehensively analyzed. Considering characteristics of medium-low speed maglev transit, optimization measures are proposed from different aspects such as different line laying modes, station spacing, station size, interval bridge structure, track engineering, electromechanical system and vehicle base, forming a systematic reference system for cost control. Results show that measures including reasonable station spacing, increasing subgrade laying length, and controlling station size can effectively lower project construction cost; bridge pier size optimization and selection of parallel track beams can save a significant amount of building materials; competitive bidding, standardized and modularized track design are key factors in controlling the cost of track engineering; the concept of value engineering should be fully utilized in electromechanical system design; and vehicle base layout design should be optimized in both general layout and vertical arrangement.
