"In this scene of a couple on a train late at night, Hopper places us across the aisle as an observer. He compresses a sense of psychological drama within a narrative framework. He uses his favourite compositional device of an oblique, or angled, viewpoint. It is emphasised here by the row of seats on the right hand side of the etching. The movement of the train is indicated by the billowing blinds and swaying straps." http://www.britishmuseum.org/explore/highlights/highlight_objects/pd/e/edwa
