In a bid to ensure more convenient, eco-friendly transportation and improve the quality of life of people in metropolitan cities, India is all set to expand its metro rail network to approximately 2,000 km over the next seven years. While in the last thirty years, India has added 20-25 km per annum of metro rail network, it is now looking at an expansion of 175-200 km per annum over the next seven years.

India is set to increase its metro network from an existing operational 851 km to a planned 1,985 km over the next five to seven years. This will take India’s investment in metros to Rs.6,838 billion.

The average cost of building a metro is currently around Rs.407 crore per km. The cost depends largely on whether the metro is built underground (higher) or at ground level. The other factor that influences the cost is the timeliness of implementation. Cost escalations are imminent whenever the projects are delayed due to design or implementation issues.
