Streetcars are just like telegraphs or kerosene lamps — they are symbols of history. Indeed, I can hardly remember any city which still has streetcars as a part of the public transportation system nowadays. Yet, New Orleans is one of them. There are four streetcar lines currently operating in New Orleans, and one of them, namely the St. Charles Avenue Line, is said to be the oldest continuously operating street railway system in the world. Sometimes I can see young boys or girls run along the streetcar rails, which reminds me of the cable car heading to the top of Victoria Peak in Hong Kong. I guess this is the magic power of time: memories are refreshed with similar scenes, and histories are revisited with legacies from the past.
