Abstract ： Research purposes ： DC system is recommended in the engineering of Hangzhou to Lin an inter - city railway， because the network system is the same as Hangzhou metro, and also it's connecting with the network，there are two possible ways of the transfer model： transference and cut - through. Based on passengers comfort, operation organization management，system capability and engineering scale，the paper compares and analyzes the rationality of two transfer modes, determines the transfer mode in current planning environment, and finally proposes the key factor of the transfer mode between the similar inter - city railway engineering and metro network. Research conclusions ： (1 ) The key factors determining the transfer mode between DC system inter - city railway and metro network are the volume and exchange capacity of the passenger flow. (2) If the passenger flow volume is well - matched or exchange capacity of the passenger flow is large, the cut - through operation of the two transport lines is more necessary. (3) We need to focus on analyze the passengers'comfort，the system capability of connecting line and the impact on the engineering investment， to select the detailed scheme of cut - through. （4) Considering the connecting plan of transference， we should try to achieve the multipoint transference of inter - city railway and metro network. (5) The research result has reference value of determining connection mode of the inter - city railway and metro network.
