The book takes the form of a dialogue between the two authors, here rendered simply as J and A, infusing them with a fictive resonance as well as the weight of their reputations, accomplishments and autobiographies. Railtracks is a unique collaboration, a profound meditation on exile and migration, separation and consolation, reunions and railways, love and loss. It moves from the industrial to the metaphysical. And from the present to a past that still exists in vivid, essential traces. It asks what we carry with us when we must leave everything behind. It fuses longing and intimacy, distance and presence. Railtracks is the original text of the London stage production, Vanishing Points, performed by the authors and Theatre Complicite, and directed by Simon McBurney.
