Abstract: A safety barrier for a subway or railway train including pairs of individual pivoting triangular gate members with a smooth wall panel at the base of the triangle. Each gate member is retractable within a recess in the end wall of the train car near a corner and are expandable to form a partial continuation of the side wall of the train car and to form with an adjacent barrier on the rear end wall a safety barrier to prevent persons from entering the gap between the cars from either side of the train.

Abstract: A floatable snowmobile make up of a one-piece molded plastics body comprising an engine compartment with a recess defined therein for receiving an engine and accessories; an elongated seat-bench provided with a recess for receiving a track assembly; and a cargo support extending rearwardly thereof. The molded body includes a rigid skin forming the shell defining an enclosed cavity in which there is provided an expanded closed-cell foam core of water-buoyant material. The skis are constructed as pontoons of similar construction to the body, and the whole snowmobile can float with a portion thereof out of the water so as to support a rider clear of the water in the event the snowmobile falls through ice.
