The subject is about Moynihan Train Hall. I had been living on Long Island, and every time I came to New York, I took the LIRR to get to Penn Station, and left from Moynihan Train Hall at night. Moynihan Train Hall is constantly changing and a bridge to my memories. Trains and subways are vital to people, both for commuting and for travel. I think the most interesting thing is the expression of those people, you can tell by their emotions the purpose of taking public transport and their personal situation.
