Smaranika Tram Museum is housed in a decommissioned tram and tells the story of Kolkata's tram system, one of the oldest in Asia and the last operating tram network in India. Displays cover the network's long history and its place in the city's street life.
It is a small, specialist stop rather than a major museum. Pair it with a tram ride or a walk through central Kolkata if you are interested in heritage transport.
