The South-link line (Chinese: 南迴線; pinyin: Nánhuí Xiàn) is a line of the Taiwan Railways Administration running across the southern tip of the island of Taiwan, connecting the eastern and western coasts. It is 98.2 km long, of which 81.4 km is single-track. The section between Nanzhou and Linbian railway stations was upgraded from a single-track railway to a dual-track railway while the other sections remains in single-track. In conjunction with electrification works on the line, train platforms are being lengthened and upgraded with better facilities.
