Vintage Train on NYC Subway!

This afternoon, on my way home from Trader Joe's, a strange vintage train approached the 2/3 train platform. I was confused, but people were getting on, so I joined as well. Turns out it's a train HBO is running on weekends to promote Boardwalk Empire. That is some serious marketing strategy. I know nothing about the show nor how it relates to vintage NYC train, but now I sure want to google and find out. Whomever came up with this idea is pretty genius! It was cool to be able to ride in an old train and imagine what life is like back then. I am a sucker for historical things, and being able to experience it makes it that much more exciting than seeing it in the museum!
