This line starts from Uliassutai and runs on the track of the Gaskhiun-Tannu Ola line, until it reaches the Eder River, a branch of the Selenga. Then, turning off eastward, it begins its own course and proceeds downward following the course of the Eder River, crossing the Tsingpien-Tannu Ola line, to the junction of this river with the Selenga. There it joins the Kalgan-Urga-Tannu Ola line and proceeds together eastward in the common track for some distance until the other line turns southeastward, when this line turns northeastward following the Selenga down to Kiakata. This line covers a distance of about 550 miles, running through a fertile valley. j. The Chensi or Barkul-Urga Line This line starts from Chensi or Barkul and proceeds northeastward across a cultivated region through Tutaku to Urkesiat. After Urkesiat, it crosses the Suchow-Kobdo line, then traverses the vast pasture on the north side of the Gobi Desert to Suchi and Dalantura. Thence it turns more northward across the Great Eastern Port-Uliassutai line, and the Dolon Nor-Urumochi line to Tashunhutuk. After this point the line crosses the Suiyuan-Uliassutai line at Ologai and proceeds over the watershed into the Selenga Valley where it crosses the Tsingpien-Tannu Ola line at Sabokatai. From here it turns eastward across a hilly and watered region to Urga. This line covers a distance of about 800 miles. k. The Suchow-Urga Line This line starts from Suchow and proceeds by Kinta to Maumu, and then follows the Taoho or Edsina River, which waters this strip of oasis, to the lakes. Thence it crosses the Gobi Desert, where it meets the crossing lines of the Peking-Hami and the Great Eastern Port-Uliassutai railways and with them forms a common junction. From this junction it proceeds across desert and pasture lands to another railway crossing which is formed by the Suiyuan-Kobdo and Tsingpien-Tannu Ola lines, also forming a common junction together. Thence it proceeds into pasture land through Hatengtu and Tolik to Sanintalai, where it crosses the Dolon Nor-Urumochi line. After Sanintalai, the line proceeds through Ulanhoshih and many other small towns and encampments to Urga. This line covers a distance of about 700 miles. One third of this length is through the desert and the other two thirds through watered pasture land. l. The Desert Junction-Kerulen Line
