To enhance the applicability of the trestle bridge for train ferries, a novel flexible linkspan is put forward which can be hinged to shore at one end and moved up and down and also left and right at the other end, and hence can be connected to various decks on board to facilitate the loading or discharging of rolling stock. The basic configuration of the flexible linkspan and the assembling feature of its main parts are presented with a description of its working mechanism. The key parameters of the flexible linkspan, such as transverse moving distance of the moving end, turning angle of the linkspan, overhang length of carlings, are also formulated. The initial research outcomes show that the new type of flexible linkspan is feasible and practical.
