Discussion on planning of transforming idle railway into urban railway in Tianjin terminal

Research purposes: As the rapid expansion of the city scale, traffic problem has become a major contradiction. The most effective way of solving this problem is to develop the urban mass trasit. But the current problem is: on one hand, as the rapid construction of the railway, part of the railway resources lie idle, on the other hand, the construction of urban mass transit need a large number of funds and precious urban track resources. This paper analyzes how to make the idle railway give play to the urban transit function in Tianjin terminal, and hope to provide references for the diversification mode choice of the urban mass transit in other cities. Research conclusions: (1) Use the existing railway and the newly built railway to form a circuit urban railway which includes Tianjin Station- Tianjin North Station-Xiyingmen Station-Chentangzhuang Station-Tianjin Station. (2) Use the surplus transportation capacity of the Tianjin-Shanhaiguan line to run urban trains from downtown to Binhai New Area. (3) Use the abandoned railway and part of newly built railway to form the transit track from downtown to Jinghai and Dagang, and run urban trains. (4)Use the existing railway double line project to form the transit track from downtown to Baodi and Ji county, and run urban trains. (5)This result can provide the reference for other cities.
