The purpose of all the rules in TM 55200 is to insure the safe
and efficient operation of trains over military railroads. Trains
have superiority by right, by class, or by direction established by
either train order or timetable. Remember that any train having
superiority by class or direction established by a timetable may have
that superiority changed by a train order. When one train is given
superiority over another by train order, its superiority is by right
conferred by the train order.
The four types of trains normally found in a theater are
freight, passenger, ambulance, and work trains.
