I was traveling home from Mallorca and stopped off in Barcelona for a day of site seeing. The subway system there is comparable to London's underground. While waiting for a train back to The Ramblas (famous street in Barcelona) I snapped this shot from the platform. The movement of the car, stillness of one of its passengers and the person crossing frame is a microcosm of underground travel.
