Train In-station Coupling and Decoupling Scheme for Shanghai Metro Line 16

Abstract

Objective Shanghai Metro Line 16 adopts a flexible marshalling operation mode, but it takes a long time for the train to complete the coupling and decoupling process, leading to great difficulty in train operation organization. In order to further improve the operation efficiency and simplify the train operation organization, an in-station coupling and decoupling scheme is put forward. Method Based on Shanghai Metro Line 16, the problems that need be solved for train in-station coupling and decoupling are analyzed. In view of the above problems, a concrete implementation scheme for the train in-station coupling and decoupling is put forward. Several tests are carried out on Shanghai Metro Line 16 to verify the effectiveness of the scheme. The main rules about operation safety specified in "Specification on train coupling and decoupling in Longyang Road Station of Shanghai Metro Line 16" are introduced. Result & Conclusion Longyang Road Station, a terminal turnaround station with minimal impact on the line operation, is selected for the coupling and decoupling site. The function of coupling and decoupling operation in the station is realized through modifying the ATS software chain logic and defining a special parking area in the station for coupling and decoupling operation. The test results verify the safety and feasibility of the scheme.
