Abstract：Research purposes: Train is the direct carrier of passengers in urban rail transit，and train marshaling form involves the urban planning， passenger flow，train operation， line network resource sharing， and so on. From the perspectives of urban rail transit line characteristics，traffic volume forecasting， vehicle capacity， transport capacity matching，line network resource sharing，dynamic ratio of motor cars and trailers and economy，the optimal Jinan rail R1 line train marshalling was determined through the break - even analysis. Research conclusions:(1) Considering various factors，4-4-6 mar sliding is recommended for Jinan rail transit R1 in the early，the near future and the far future stages. The ratio of motor cars and trailers is 3 ： 1 in the early and the near future，4 : 2 in the far future. (2) Passenger flow prediction is the main factor affecting vehicle type and train marshalling selection，depending on urban planning and development. (3) According to the breakeven analysis，train expansion after 10 years of operation is a more economical solution. (4 ) The results have been applied on the design of Jinan rail transit R1，and can provide a reference for the similar projects.
