Section 25.22 - Railway movement and traffic

(a) Movement relative to railway buildings. Before cars are moved into or out of a railway building or before coupling is made to any car within a building, a trainman shall walk the full length of the cars to insure that no one will be injured by the train movement and that all obstructions are removed.

(b) Insuring clear tracks. There shall always be a member of the crew at the head end of a moving train to warn anyone along the track who may be in danger, except when hot metal or hot cinders are being handled. With the locomotive pointed forward at the head end of the train, the engineer in his proper place in the cab shall be regarded as being at the head end of the train. When a train is moving on tracks where vision is obstructed, it shall be ascertained by some member of the crew that the track is clear before movement proceeds.

(c) Starting signals. The engineer shall not knowingly act on a starting signal given by any person except a member of the crew. No person other than a member of the crew shall couple or uncouple cars.

(d) Precedence of trains on intersecting tracks. Where one track crosses another track, there shall be established a rule giving trains on one track precedence over those on the other track, at the point of intersection.
