mini 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.
d. The Tungchin-Kerulen Line
This is the fourth line that radiates from the Tungchin Railway center. It runs in a northwesterly direction almost parallel with the Harbin-Manchuli line of the Chinese Eastern Railway, the distance between the two lines varying from 100 to 130 miles. The line starts from Tungchin on the north side of the junction of the Nonni and Sungari rivers and proceeds westward across the Nonni River to Talai, and then turns northwestward across the plain into the valley of the north branch of the Guileli River. After entering the valley, it follows the stream up to its source, then crosses the Great Khingan Mountain watershed into the Mongolian Plain by the Khalka River, and follows the right bank of this river to the north end of Bor Nor
