Sangtolohai. Thence turning southwestward, it proceeds to Namaling and Tangto, and crosses the Sanpo River at Lhaku. After Lhaku, the line turns westward to Shigatse, the second important city in Tibet whence it proceeds in the same direction to Chashihkang, Pangcholing, and Lhatse all on the right side of the Sanpo River. From Lhatse, a branch line starts southwestward via Chayakor and Dingri to Niehlamuh on the Nepal border. The main line, however, crosses to the left side of the Sanpo River and proceeds on the same highway via Nabringtaka to Tadum where another branch line proceeds southwestward to the Nepal border. The main line continues northwestward via Tamusa and Choshan to Gartok, thence turning westward it proceeds to Laichiyaling on the Sutlej River and ends on the Indian border. This line, including the two branches, covers a distance of 850 miles.
