Contracts Scope of Work: Provision of High Conductivity Aluminium Third Rail in Elevated Section of North South Corridor of Metro Railway, Kolkata (Phase-III).
The Blue Line is the main operational corridor of Kolkata Metro, extending 32.25 km from Dakshineswar to Kavi Subhash, with 26 stations along the route. It carries the highest passenger volume among all metro corridors in the city.
Recent expansions of other metro corridors have led to an increase in passenger traffic on the Blue Line due to improved network connectivity. Among the stations, Dum Dum records the highest daily footfall, with over 66,000 passengers in late September. The planned installation of high conductivity aluminium third rail is expected to improve operational reliability, reduce maintenance requirements, and ensure consistent power supply for train operations. This initiative aligns with Metro Railway’s efforts to upgrade existing infrastructure.
