The proposal for construction of Railway lines along China, Nepal and Pakistan border has been initiated by Ministry of Defence as a strategic line. A total of 14 Strategic lines have been identified, out of which four strategic lines viz. (i) Missamari – Tenga – Tawang (378 Km) (ii) Bilaspur – Manali – Leh (498 Km) (iii) Pasighat – Tezu – Rupai (227 Km) and (iv) North Lakhimpur – Bame (Along)-Silapathar (249 Km) have been decided to be taken up in first phase. None of these projects has been sanctioned. Since all these projects pass through very difficult terrains of young Himalayas, stability, geology, constructability, maintainability and safety issues are to be examined. Accordingly, Final Location Survey (FLS) has been taken at a cost of Rs. 345 Crore. For the year 2016-17, Ministry of Defence has provided Rs. 87.18 Crore.
