Subways and trains are a routine part of everyday life for many. So routine, that some passengers appear able to be practically asleep while boarding and departing their daily stops. As a kid in Chicago, riding the train never felt mundane to me. Growing up in a traditional and conservative Yemeni family, it would be an understatement to say that my freedoms were limited as a young girl.  I still remember how liberating it felt to ride the bus alone for the first time.  Taking the train was even more exhilarating. They were gateways to an independence and greater mobility I would only later experience as an adult- unfortunately at the sacrifice of being estranged from my family for years.
To this day,  I am fascinated by buses, trains, trams, etc.;  moving capsules that, for a brief period of time,  closely hold together a mix of individuals with completely different lives.
