It could well be one of Mumbai's marvels - the subway that floods despite a drop of rain! An ambitious project for BMC, as one of the city's longest subways under Kurla station's 10 parallel tracks, it was built at a cost of about Rs 9 crore. But the money spent on the Kurla subway seems to have gone down the drain.
