Visakhapatnam railway station

Visakhapatnam railway station is a major railway station located in Visakhapatnam, Andhra Pradesh, India. The railway station is under the control of East Coast Railway of Indian Railways. It stands on the Howrah-Chennai main line, though the mainline bypasses Visakhapatnam Central Station. Consequently, a suburban halt on the mainline near Vizag Steel Plant, known as Duvvada, is being developed into a major station to improve services for the city.The city's railway station was originally called Waltair railway station. In around 1987, Mr. D. V. Subbarao, the then mayor of Visakhapatnam, changed the name to Visakhapatnam which is largest railway station under east coast railway and A1 category station. Visakhapatnam railway station is administered by the East Coast Railway of Indian Railways and is the headquarters for the Waltair Railway Division. It will be de-linked from East Coast Railway once a new railway zone for Andhra Pradesh is formed and will be part of new zone according to AP Reorganisation act 2014.OverviewThe station is a terminal station; trains must go back the same way as they come. With many trains arriving at the same time platforms are not always available. In case any train is late, the other trains are stopped at Duvvada or Vizianagaram. The Route Relay Interlocking (RRI) system, an arrangement of signal apparatus that prevents conflicting movements through an arrangement of tracks such as junctions or crossings, is reported to be one of the major causes for these trains being delayed after Duvvada Station.
