The Rs 8,070-crore Bairabi-Sairang railway line, considered one of the most challenging in Indian Railways' history, was sanctioned in 2008-09 and construction began in 2015

The line includes 45 tunnels, 55 major bridges and 87 minor bridges

Bridge No 144, near Sairang, is taller than Qutub Minar at 114 metres. It is the tallest pier railway bridge in the country, an official of the Northeast Frontier Railway said

The route also features five road overbridges and six underpasses, covering four main stations -- Hortoki, Kawnpui, Mualkhang, and Sairang -- apart from Bairabi

The direct rail connectivity between Mizoram and the rest of the country will offer the people of the region safe, efficient, and cost-effective travel options

It will also ensure the timely and reliable supply of food grains, fertilisers, and other essential commodities, thereby enhancing overall logistical efficiency and regional accessibility, the PMO said in a statement

Officials said the new railway line will improve passenger and freight connectivity, reduce travel time, boost tourism and employment, and fulfill a long-standing demand of the Mizoram public
