non-crossing overhead crossing of OCS above the turnout of No.42 is a structural type for transition of OCS between tracks of high-speed railways.Its deign mode is relatively mature but there are several design problems occurred in the process of operation.The paper,through analyzing of the problems existed in the structural design and operation of non-crossing overhead crossing for OCS above turnout of No.42,puts forward proposals for its improvement,providing reference for design optimization,operation and maintenance of OCS non-overhead crossings.
