d. The Tsingpien-Tannu Ola Line

This line starts from Tsingpien at the Great Wall, on the northern border of Shensi, proceeds through the Ordos country by Bonobalgasun, Orto, and Shinchao, and then crosses the Hoangho to Santaoho. From Santaoho, it proceeds across Charanarinula Mountain into Mongolian prairie in a northwesterly direction to Kurbansihata where it crosses the Peking-Hami line, then it goes to Unikuto and Enkin, where it crosses the Great Northern Port-Urumochi line. After Enkin, the line enters into a valley and watered district, proceeds northward to Karakorum, and then turns northwestward across various streams and valleys of the tributary of the Selenga River by Sabokatai and Tsulimiau. After Tsulimiau, it proceeds in the same direction across the Selenga River, follows its branch, the Telgir Morin River, up to its source and crosses the watershed into Lake Teri Nor. Then it follows the outlet of the Teri Nor to the Khua Kem River, where it ends by joining the Kalgan Urga-Tannu Ola line. This line covers a distance of about 1,200 miles.

e. The Suchow-Kobdo Line

This line starts from Suchow in a northwesterly direction penetrating the Great Wall at Chiennew, and proceeds to the coal field, about 150 miles from Suchow. Then it goes to Habirhaubuluk and Ilatoli. A short way from this place the line comes across the Peking-Hami line and then proceeds to Balaktai. After this the line passes a bit of pure desert to Timenchi. After entering the hilly and watered country it proceeds to Gaskhiu where it crosses the Great Northern Port-Urumochi trunk line. After Gaskhiun, it proceeds to Wolanhutok, Tabateng, and Tabutu where it joins the Kucheng and Kobdo highway and following it, proceeds to Kobdo, through Batokuntai and Sutai. Here the line ends, covering a distance of about 700 miles.

f. The Northwestern Frontier Line

This line starts from Ili following the Urumochi-Ili line to Santai, on the eastern side of Zairam Lake, then proceeds northeastward by itself to Tuszusai on the west side of Ebi Lake. After Tuszusai it proceeds to Toli where it crosses the Central Trunk line, that is, the Great Eastern Port-Tarbogotai line. Thence it goes to Namukotai and Stolokaitai by passing through a vast forest and a rich coal field. From Stolokaitai, the line follows the highway and proceeds to Chenghwaszu, the capital of Altai province. Thence it crosses a mountain range by the Urmocaitu Pass into the Kobdo Valley, and follows the course of the Kobdo River to Beleu where it joins the Suiyuan-Kobdo line and proceeds to Clegei. From Clegei, it proceeds by itself to Tabtu via Usungola and Ulamkom. At Tabtu, it joins the other line again and proceeds together to the Khua Kem River in the Tannu Ola district. It then turns eastward ascending the river to the junction of the Bei Kem and Khua Kem rivers, then starts again on its own course, following the former river and proceeds up to its source in a northeasterly direction ending at the frontier. This line covers a distance of about 900 miles.

g. The Tihwa or Urumochi-Ulankom Line

This line starts from Tihwa following the Dolon Nor trunk line to Fowkang, then proceeds by its own route almost northward through Chipichuan to Khorchute. From Khorchute, it turns northeastward and proceeds across a hilly district to Kaiche, then to Turhuta, where it crosses a branch line from Junction C. of the Great Northern Port-Urumochi line. After Turhuta, it turns northward, proceeds up the Pakaningale Valley to Zehoshita, and then crosses the Tilikta Pass. Thence it turns northeastward proceeding across the newly cultivated country to Kobdo. After Kobdo, it proceeds through a fertile plateau, by crossing many rivers and skirting many lakes to Ulankom, where it ends by joining the Northwestern Frontier line. It covers a distance of about 550 miles.

h. The Gaskhiun-Tannu Ola Line

This line starts from Gaskhiun and proceeds northeastward across a hilly and watered country through Hatonhutuk and Talangjoleu, to Pornulu. After Pornulu, the line proceeds across the Sapkhyn Valley by Huchirtu and Porkho to Uliassutai where it meets the Suiyuan-Kobdo, and the Great Eastern Port-Uliassutai lines. After Uliassutai, the line proceeds northward to a quite new country by first crossing the headwaters of Selenga, then the headwaters of the Tess River. In the Tess Valley the line crosses a vast virgin forest. After emerging from this forest it proceeds northwestward across the watershed into the Khua Kem Valley in Tannu Ola and ends by joining the Northwestern Frontier line. This line covers a distance of about 650 miles.
