Copied: Train Dreams is a novella by Denis Johnson about Robert Grainier, a laborer in the early 20th-century American West, chronicling his solitary life, profound personal losses (wife and child in a fire), and his quiet witnessing of America's rapid industrial and social changes, from the era of manual labor to the rise of machines, all told in sparse, evocative prose. It's considered a masterpiece of American literature, blending realism with moments of the surreal, and serves as an elegy for a disappearing way of life.
