Naugachia railway station

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 120 kilometres (75 mi) from east to west. In August 2008, it picked up an old channel it had abandoned over a century ago near the Nepal–India 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.[1] The floods continue and threaten even the Barauni–Katihar 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."[2]

Electrification of the 809 kilometres (503 mi) long Barauni–Katihar–Guwahati section was sanctioned in 2008.[17] As of 2011, work on electrification of Barabanki–Gorakhpur–Barauni–New Jalpaiguri route was in progress. Adequate funds have been provided in the budget for 2011–12 to take up work in the New Jalapiguri–New Bongaigaon–Guwahati section.[18] 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.
