A short (8-minute) documentary about the last trams in India: those of the 149-year-old Kolkota tram system. It’s on its last legs, down to 12–15 trams from its height of 300, and there are suggestions that the government of West Bengal will shut the service down.

Activists are fighting to save it, both as a symbol of Kolkata’s history and heritage and as a cheap, environmentally friendly and low-congestion method of transport in what is an increasingly crowded and polluted city.
