From the 19th century onward, trains have occupied a central place in literature, not just as a mode of travel but as a rich symbolic setting. Their enclosed spaces bring together strangers of different backgrounds, creating a natural stage for tension, intimacy, and conflict. At the same time, the forward motion of the train often mirrors the narrative drive of the story itself: a journey with a fixed beginning and end, hurtling toward revelation or catastrophe.

Classic examples highlight these dual qualities. In Agatha Christie’s Murder on the Orient Express (1934), the opulent train becomes a claustrophobic container for mystery and moral ambiguity, its physical confinement forcing characters to confront one another. In Leo Tolstoy’s Anna Karenina (1877), trains symbolize both modern progress and destructive inevitability, culminating in the novel’s tragic conclusion. Later works such as Patricia Highsmith’s Strangers on a Train (1950) exploit the anonymity of train travel to explore psychological suspense and moral compromise.

Riley Sager’s With a Vengeance inherits this tradition. By setting the novel aboard the fictional luxury train the Philadelphia Phoenix, Sager draws on the glamour and peril associated with rail travel during its golden age while also using the train’s confinement to heighten suspense. Characters cannot escape each other; the steel corridors and compartment doors become both literal and metaphorical barriers, locking them into a battle over guilt, truth, and vengeance. The train also functions as a liminal space—neither origin nor destination, but an in-between zone where past crimes come hurtling into the present.

In this way, With a Vengeance underscores why trains remain so potent in literature: They are microcosms in motion, spaces where fate feels inescapable and the tracks beneath the wheels echo the inexorable pull of destiny. By fusing the train’s physical confinement with the characters’ moral entrapment, Sager extends the long literary tradition of trains as spaces where human flaws are magnified and judgment becomes unavoidable.
