Metro rail is fast becoming the most popular means of mass rapid transit in India with an operational network of over 660 km across 12 cities. But did you know that the first metro in the country started operations all the way back in 1984 in Kolkata. It is also the only metro rail network that is controlled by the Indian Railways; all others are operated by autonomous local authorities.
