Meter gauge railway track that was built by the British way back in the last decade of the 19th century through the most difficult Barail mountains in Assam’s Dima Hasao district, and was always referred to as an engineering marvel, has become history. The zig-zag metre-gauge track whose tunnels and bridges were a major attraction. This was one of the most adventurous, scenic , most beautiful and the most riskiest Meter Gauge Railway track of the Indian Railways. This is the only Heritage Trail of North East India. It could be the prime attraction of Assam Tourism in near future. Hope Indian Railway and both State & Central Government will take necessary action in this regard.
