A feature one doesn’t see modeled very often is white extra flags. On a line like the North Montana that hosted mostly time freights, extra trains carrying livestock and grain were seasonal. Extra flags can be easily made from .008″ brass wire and small squares cut from white tissue paper. After gluing the flags onto the brass staffs, drill no. 80 holes on the roof corners of each side of the engine cabs (or on either side of the smokebox on steam engines). The wires can be inserted without gluing, and they will alert your engineers that those trains aren’t on the timetable. If an engine isn’t being used on an extra, simply pull the flags out.
