Many old cities have either retained or phased out their old road-level transit systems. I am referring mainly to rail-based streetcars rather than road-based ones such as buses. Even the indigenous types of road-based public transport may be phased out and usually in the name of modernization. Some though, like Singapore’s rickshaws and Manila’s calesas are still existent but you will find them either during odd hours or in tourist areas.
A good example of a city that has retained and preserved its transit system that is San Francisco in the US. The city still has a running cable car system, and its street cars maintained and operated by the San Francisco Municipal Railway (Muni). These are practically operational, traveling museums. The streetcars, for example, are of different models – a collection of streetcars from various cities around the world that have phased out this transit systems a long time ago. So it should not be surprising to see a different street car every time. And one could try to ride each one in operation while staying in city.
Here is an article about Kolkata’s (Calcutta’s) trams:

What are your thoughts about preserving or phasing out these transit systems?
