Kaohsiung Metro
The Yellow line has not been finished yet, but it will become the third rapid transit line of Kaohsiung Metro once it opens for service. The Yellow line is expected to open by 2028, and will be 22.91 km long with 23 stations. The line will run through Kaohsiung's Niaosong District, dividing into two branches near Chengcing Lake: one towards Cruise Terminal and the other towards Cianjhen Senior High School. The Yellow line will use a medium-capacity rail system and will be mostly underground.
