North Eastern Railway is one of the most important transit zones, that is, it is used to take in loaded wagons, especially food grains, from Northern Railway divisions like Firozpur, and move it towards Eastern belt and the Northern Frontier region (Seven Sister States). Thus, it acts as an essential cog in the food security of the country. Apart from being an important transit zone, it is also at the center-stage for much inward traffic from the neighboring zones. The inward traffic comprises food grains, fertiliser, stone chips, cement, petroleum, coal, etc.
