context_page_description: The Northeast Frontier Railway, is one of the 18 railway zones in India. Headquartered in Maligaon, Guwahati in the state of Assam, it is responsible for rail operations in the entire Northeast and parts of West Bengal and Bihar.
context_section_description: The area of Northeast Frontier Railway operations is characterized by exceptional beauty and at the same time by some of the most arduous terrain.  This difficult terrain limits the rail network expansion, and the only state with a decent rail network is Assam.  The network is not broad gauge in many parts and the rail lines are antiquated with speeds at some sections being limited to a maximum of 30 km/h (19 mph).  Before the Saraighat Bridge was constructed, passengers had to get down on the Amingaon side of the Brahmaputra and take a ferry across to Pandu Junction from where they could resume their journey.
  The majority of the tracks have been converted to BG and electrification is in process starting from Katihar till Guwahati.
