Note. End depots are numbered from 1 to 9 as follows: 1, Changlingdong depot; 2, Shekou bus depot; 3, Shenzhen North Railway Station; 4, Longgangyiwu bus depot; 5, Nanaoxinda bus depot; 6, Tantou West; 7, Hangzi bus depot; 8, Moon Bay; 9, Window of the World. The values in the brackets next to the depot index are the number of charging piles established at the depots.
