If a train approaches an unattended fusee burning on or near its track, the train must immediately be brought to a stop
           consistent with good train handling.

           Stop before passing the fusee when operating in accordance with Rule 518 (Movement at Restricted Speed) or Rule 520
           (Movement on Non-Main Track).

           After stopping, the train must proceed at restricted speed until the head end is 1 mile beyond the fusee.

           If an unattended burning fusee is beyond the first rail of an adjacent track, the fusee does not apply to the track on which 
           the train is moving.

           
           Fusees must not be used wastefully and in any case not placed where they may cause fires.
