The tramway (ding ding)
Local residents call these double-decker trams "ding ding" due to the double bell ring the trams use to warn pedestrians of their approach.
Since 1904, trams have been running east and west along the northern coast of Hong Kong Island. The tramway is a living, evolving connection between Hong Kong's colorful history and modern culture.
Currently there are a total of 164 tramcars running through Hong Kong, including two antique trams and one sightseeing tram. It is the world's largest double-decker tram fleet still in operation, carrying an average of 200,000 passengers everyday.
There are ongoing debates about whether or not to remove ding ding to give way for more modern vehicles like buses and cars on such a congested island. But Hong Kong people stood up to keep them around for nostalgic purposes.
