Bilaspur–Manali–Leh Railway Blueprint: How Ladakh’s 5,256m Tanglang La Station Beats China’s Record
Indian Railways’ Detailed Project Report (DPR) for the 489-km Bilaspur–Manali–Leh corridor maps out a ₹1.31 lakh crore Himalayan engineering feat: a station beneath Ladakh’s Tanglang La at 5,256 metres (17,244 feet), eclipsing China’s Tanggula world record.
Indian Railways has completed the survey and prepared the Detailed Project Report (DPR) for the 489-km Bilaspur–Manali–Leh broad-gauge railway line, estimated to cost ₹1.31 lakh crore (MagicBricks, Economic Times). A proposed station beneath Tanglang La pass in Ladakh at an elevation of approximately 5,256 metres (17,244 feet) would surpass China’s Tanggula station (5,068 metres on the Qinghai–Tibet Railway) by 188 metres to become the world’s highest railway station (MagicBricks). Roughly 270 km (55% of the entire 489-km corridor) will run underground through around 62 tunnels to bypass steep gradients, avalanches, and sub-zero snow closures (MagicBricks). Key planned stations along the route include Bilaspur, Beri, Sundernagar, Mandi, Manali, Sissu, Darcha, Keylong, Sarchu, Pang, Rumtse, Tanglang La, Upshi, Kharu, and Leh (MagicBricks). Because oxygen and atmospheric pressure drop sharply above 17,000 feet, coaches on the upper Ladakh stretch are planned to use aircraft-style pressurised, heated cabins with supplemental oxygen systems for soldiers and civilian passengers (MagicBricks).
| Parameter | Detail |
|---|---|
| Length | 489 km |
| Cost | ₹1.31 lakh crore |
| Tunnels | 62 tunnels / 270 km (55% underground) |
| Tanglang La Station | 5,256 m (17,244 ft) |
| China Tanggula Station | 5,068 m (16,627 ft) |
| Stations | 14+ (Bilaspur to Leh) |
Once approved and constructed, the 489-km Bilaspur–Manali–Leh railway will transform Ladakh from a winter-isolated air-and-road outpost into an all-weather rail corridor capable of moving military freight and tourists year-round. However, because the ₹1.31 lakh crore project requires boring 62 tunnels across 270 kilometers of fragile Himalayan rock—and awaits final Cabinet construction clearance—travellers and investors should treat the 5,256-metre Tanglang La station as a completed DPR blueprint rather than an active construction site (MagicBricks, Economic Times).
Bilaspur Manali Leh railway world highest station: 62 tunnels, pressurised cabins and Himalayan hurdles
More than half of the entire railway to Ladakh—270 km out of 489 km (55.2%) across 62 tunnels—will actually run inside the Himalayan mountains rather than over them, including the record-breaking station at Tanglang La (5,256m / 17,244 ft), which is planned as an underground/sub-pass station beneath the 5,328m highway pass to shield trains and passengers from -30°C winter blizzards (MagicBricks).
Because oxygen and atmospheric pressure drop sharply above 17,000 feet, coaches on the upper Ladakh stretch are planned to use aircraft-style pressurised, heated cabins with supplemental oxygen systems for soldiers and civilian passengers (MagicBricks). The Bhanupali–Bilaspur feeder link is still resolving land acquisition and geological tunnelling challenges (MagicBricks, Economic Times).

While TV headlines claim the Tanglang La station is already “being built,” the Ministry of Railways record shows the DPR is prepared and awaiting final Cabinet financial sanction, while the feeder line from Bhanupali to Bilaspur is still resolving land acquisition and geological tunnelling challenges (MagicBricks, Economic Times). Building Tanglang La station beneath the pass inside a tunnel is what makes year-round operation at 17,244 ft possible, shielding trains and passengers from -30°C winter blizzards.
Which railway station in India will become the world’s highest, beating China’s record?
India’s Detailed Project Report (DPR) for the 489-km Bilaspur–Manali–Leh railway line proposes building a station beneath the Tanglang La pass in Ladakh at an elevation of approximately 5,256 metres (17,244 feet). Once constructed, it will surpass China’s Tanggula railway station (5,068 metres on the Qinghai–Tibet line) by 188 metres as the world’s highest railway station (MagicBricks, Economic Times).
What is the estimated cost and total length of the Bilaspur–Manali–Leh railway project?
The DPR estimates a 489-km line at ₹1.31 lakh crore, with 62 tunnels covering 270 km (55% underground) (MagicBricks, Economic Times).
What are the key stations on the Bilaspur–Manali–Leh railway route?
Key planned stations include Bilaspur, Beri, Sundernagar, Mandi, Manali, Sissu, Darcha, Keylong, Sarchu, Pang, Rumtse, Tanglang La, Upshi, Kharu, and Leh (MagicBricks).
Why will trains on the Leh railway line need pressurised cabins?
Above 17,000 feet, oxygen and atmospheric pressure drop sharply. Aircraft-style pressurised, heated cabins with supplemental oxygen systems are planned for soldiers and civilian passengers (MagicBricks).
The summit now heads toward its final days. Delegates will meet for the closing plenary in Antalya on November 20. That is where the negotiating text gets its final test. Observers will check whether the words missing from the keynote appear in the agreed outcome.
