Prolific, pioneering Canadian film-maker James H. White’s 104th Street Curve, New York, Elevated Railway is a gently engaging two-shot short documentary.
"Taken from the front platform of a special train run backward over this celebrated S curve. Not only are the passing trains and crowded platforms of great interest, but the view of uptown New York is an excellent one, showing acre upon acre of roofs, towers, steeples and towering apartment houses. As the ‘special’ slows up at 92nd street, a Harlem express dashes by, the engineer leaning out of his cab, and waving a good-bye." TMDb
