Naugachia railway station (station code: NNA) is on the BarauniâÂÂKatihar section of the Sonpur railway division and serves the town of Naugachhia in the Indian state of Bihar.
The station lies on the northern side of the Ganges and traverses the Kosi basin. In Bihar, the Kosi is widely referred to as the "Sorrow of Bihar" as it has caused widespread human suffering over the centuries through flooding and frequent changes in course. Over the last 250 years, the Kosi has shifted its course over from east to west. In August 2008, it picked up an old channel it had abandoned over a century ago near the NepalâÂÂIndia border, and caused enormous damage in a wide area covering several districts. The breach in the Kosi embankment which caused the devastating flood in 2008, was repaired in 2009 and the river has since been flowing along its original course. The floods continue and threaten even the BarauniâÂÂKatihar tracks. The entire region portrays "a bleak picture of broken houses, flattened fields and ravaged lives, signs of all the havoc the previous floods and land erosion wreaked here earlier."
Electrification of the long BarauniâÂÂKatiharâÂÂGuwahati section was sanctioned in 2008. As of 2011, work on electrification of BarabankiâÂÂGorakhpurâÂÂBarauniâÂÂNew Jalpaiguri route was in progress. Adequate funds have been provided in the budget for 2011âÂÂ12 to take up work in the New JalapiguriâÂÂNew BongaigaonâÂÂGuwahati section. The section is fully electrified. Most of the Delhi and Amritsar-bound trains run on electric locomotives. Amrapali Express was the first train to run on electric locomotive, then after Rajdhani Express, North-east Express, Purvottar Sampark Kranti Express, Seemanchal Express, Tripura Sundari Express have electric engines.
