Apparatus (300, 400) for laying an elongate member such as a pipe (306) or a rail (472). Material carried by the apparatus is smelted in a furnace (340) and fed to a casting head (342) by which the elongate member is continuously cast. The so cast elongate member is then laid by the apparatus, as it travels on the ground surface.

Abrégé

Apparatus (10) for applying a surface layer to a rail (16). The apparatus (10) is mounted to a locomotive (14) for movement along the rail (16). A barrier structure (70) of the apparatus (10) has side walls (20, 22), in use disposed against sides of the rail, and spaced forward and rear walls (40, 42) extending between these. In an initial condition, forward wall (40) and rear wall (42) extend downwardly to the upper surface (36) of the rail. Granular metal in a receptacle (62) is fed to a space (72) defined between the walls (20, 22, 40, 42) and heated by application of electric power to electrodes (84,84) extending into the space, to form molten metal. Some of the molten metal sets against the rear wall (42), after which the rear wall is moved upwardly to be clear of the rail. The locomotive (14) is then operated to transport the apparatus (10) along the rail so that molten metal is progressively deposited on the rail forwardly of the originally set metal. When set, the deposited metal forms an integral layer (100) of metal on the rail (16).
