Kolkata, May 2 (PTI) To strengthen Kolkata Metro Railway capacity, works worth Rs 671.72 crore have been sanctioned for strengthening the North–South Corridor, an official statement said on Saturday.
The estimated project cost includes setting up seven new traction substations at a cost of Rs 291.06 crore along the Blue Line.
For augmentation and upgradation of auxiliary substation (ASS) and traction substation (TSS) systems from Esplanade Metro to Kavi Subhash – New Garia in the North–South corridor, the metro railway statement said.
For augmentation of power supply at elevated sections from Netaji Metro Station to Kavi Subhash Metro Station, including enhancement from the existing 11 KV system to 33 KV system, the Metro outlined a cost of Rs 380.66 crore.
The Metro Railway Kolkata system, built in the 1980s, was originally designed to support train operations at a frequency of about 5 minutes.
However, with rising passenger demand, the requirement for higher frequency operations has increased.
The existing substations and equipment are reaching capacity limits and face maintenance challenges due to non-availability of spare parts.
The approved upgradation will ensure reliable power supply, support higher train frequency, and improve overall passenger service, it added. PTI SUS RG
