The Togtogquwo railway station or the Tuotuohe railway station is a station on the Chinese Qinghai–Tibet Railway. It is located at 34.2331°N 92.4458°W near the railway bridge over the Tuotuo River (Chinese: 沱沱河, Tuótuóhé), which is considered the headwaters of China's great Yangtze River.[1] (Further downstream, it is known in China as the Tongtian River, Jinsha River, and finally the Changjiang).
Although both the river (Tuotuohe) and the seat of Tanggulashan Town (Tuotuoheyan) are known in Tibetan as Mar Qu. the official Tibetan name of this railway station is Togtogquwo.
The station is located next to the main urban area, such as there is, of Tanggula Town.
