India’s Metros: From Appendages to Urban Lifelines
India’s Metros: From Appendages to Urban Lifelines India’s metro systems have transformed urban mobility, with cities like Delhi, Kolkata, Bengaluru, Hyderabad, Chennai, and Mumbai leading the charge. This essay explores whether a metro system with 4–5 lines, 200 km of network, and 120 stations marks the threshold for becoming a city’s lifeline rather than a supplementary appendage.
