英文摘要：

This paper proposed a detailed definition of across-rail transport, compared the difference of across-rail transport and shared-track transport and analyzed the advantages and difficulties in the implementation. Based on the real case of the across-rail transport between underground and intercity railways in Tokyo metropolitan area, the technology reform of infrastructures, operation scheme and finance status of across-rail transport were introduced. Then, the key points of necessity and feasibility were discussed. Lastly, the advice on the implementation of acrossrail transport at the present in China was proposed.
