India plans world's highest railway station at 5,256 metres, above China's record; check route, cost and key challenges of Rs 1.31 lakh crore project

India's proposed railway link to Ladakh could set a new global record, with plans for a railway station at an altitude of around 5,256 metres above sea level. If completed along the proposed alignment, the station beneath the Tanglang La pass would overtake China's Tanggula railway station to become the world's highest railway station.
