The main line of Lalin Railway is 435.5 kilometers long. The newly-built main line is 403.1 kilometers. It is a single-track electrified Class I railway with a design speed of 160km/h.
The whole line has a base of 102.2 kilometers, 120 bridges and 47 tunnels, with a bridge-to-tunnel ratio of 74.66%; 34 new stations are newly built, and 17 stations are initially opened.
The total construction period of the whole line is 7 years, and the total estimated investment in the preliminary design is 36.674 billion yuan.
