§8474. Trains.

(a) All muck cars shall be equipped with automatic coupling devices.

EXCEPTION: Small muck cars.

(b) Couplings shall not be shifted or lined up on moving cars or locomotives. If couplings are not in line, the car or locomotive shall be stopped before they are shifted.

(c) The powder car shall be pulled, not pushed, except when switching or traveling on a dead-ended portion of the line beyond the last suitable switch, and only the motorman and the brakeman shall be on the train.

(d) Where switching of cars is being performed, a brakeman shall be provided, in addition to the motorman, to assist in the switching.

(e) When railed equipment is left standing on a track, a positive means shall be provided and used to prevent accidental movement of such equipment. Safety chains shall be used to connect cars when grades exceed one percent. Such safety chains or other connections shall be capable of maintaining connection between cars in the event of either coupler disconnect, failure or breakage.

(f) Safe speed limits for rail traffic shall be determined as the job conditions warrant and be prominently posted. Trains shall not travel faster than 12 miles per hour unless equipped with adequate air brakes in addition to those required on the locomotive to safely stop the fully loaded train on the maximum grade on which it is operated.

(g) An understandable uniform signaling means shall be developed and used for signaling the movement of trains.

(h) Long pieces of material, such as pipe, rails, etc., shall be secured against shifting or protruding over the edges while being transported by trains.

(i) During shift changes the movement of rock or material trains shall be limited to areas where trains will not present a hazard to persons coming on or going off shift.

(j) Positive means shall be provided to warn and protect the train crew from shear and crushing hazards created by unavoidable site conditions such as the lack of safe clearance and limited headroom present as trains enter or exit trailing decks and rotary dumps or pass under gantry decks.
