Taglang La or Tanglang La, elevation 5,328 metres (17,480ft), is a high altitude mountain pass in Leh district in the Indianunion territory of Ladakh. It is located on the NH3Leh–Manali Highway. Rail-cum-road tunnels are being constructed under the Taglang La, Lungalacha La (87km south of Taglang La) and Bara-lacha la (171km south of Taglang La) to cater for the traffic from existing NH3 & under-construction Bhanupli–Leh line (see also Tunnels in North West India). Once railway line is completed, the elevation in metres according to the SRTM data will make it the World's Highest Railway Station at 5,256.25 metres (17,245ft), overtaking Tangulla railway station currently at 5,068 metres (16,627ft) at in Tibet Autonomous Region of China
The elevation in metres on the local signboard is in agreement with SRTM data, however the claim of being world's second highest motorable pass is no longer accurate after construction of several other higher motorable passes and it was the 12th highest motorable pass in 2015.[1]
