Choose a photocopy of one of the train track pictures. Cut out a small section of your picture that includes a segment of the track. Glue it to your paper. Make sure you place it on the paper in a spot that matches its placement in the photograph. For example, if you cut out a section that includes the horizon line, make sure you glue the section where the horizon line will be in your drawing. If you cut out a section that is in the foreground of the photocopy, make sure you glue your section in the foreground on your paper.
