India’s rapid economic growth in the last 2 decades has made air travel accessible to the ordinary Indian. The entry of several low-cost domestic airlines has enabled the connectivity of more than 80 cities across India, and the Mumbai-Delhi air corridor is ranked among the busiest routes in the world. India’s rail network, far more extensive, covers a distance of 64,015 km, and is said to be the 4th largest network in the world, carrying 10 billion passengers annually. The Mumbai Suburban Railway alone constitutes more than half of the total daily passenger capacity of the Indian Railways.
