This document provides location information for filming. It describes four potential locations: 1) An outdoor train bridge that will be lit up and bright for a night scene. 2) The inside of a train station that can be made to seem dark and gloomy despite daylight, as the platforms are covered. 3) A post box on the side of a dark road lit only by streetlamps that will look mysterious. 4) A dimly lit kitchen where an actor will write a letter, fitting with the film's theme. All locations described are accessible for filming.
