c. The Tungchin-Dolon Nor Line

This is the third line that radiates from the railway center and proceeds nearly in a westerly direction across the plain to Taonan where it crosses the projected Aigun-Jehol line (Japanese), and also meets the termini of two other projected lines, the Changchun-Taonan and the Tsengkiatun-Taonan (Japanese). After Taonan, the line turns more southward by skirting along the foothills of the southeastern side of the Great Khingan range where vast virgin forests and rich minerals are found. Then it passes through the upper Liaoho Valley formed by the Great Khingan Mountain on the north, and the Jehol Mountain on the south and through the towns of Linsi and Kingpang to Dolon Nor, where it meets the trunk line of the Northwestern Railway system. This line covers a distance of about 480 miles, a greater part of which is on level land.
