The length of the trunk line is 15.5 km, and the total length is 23.2 km; it originates in the Hallian Mission suburb in the north, goes through Great Kien-k'ang, and terminates in the districts of Q'a-men and Gi.
The line runs in cut-and-cover tunnels and open cuts within Great Kien-k'ang (the 1857 borders of the city where level crossings are prohibited) and at ground level beyond.
The Central line's distinguishing colour is yellow on the KRT diagrammatic maps since 1948.
