This heading covers parts of railway or tramway locomotives or rolling-stock, provided the parts fulfil both the following conditions :
(¥¡) They must be identifiable as being suitable for use solely or principally with the above-mentioned vehicles; (¥¢) They must not be excluded by the provisions of the Notes to Section XVII. Parts of railway or tramway locomotives or rolling-stock include : (1) Bogies, with two or more axles, and bissel-bogies consisting of a frame with only one axle. (2) Straight or cranked axles, whether or not assembled. (3) Wheels and parts thereof (wheel centres, metal tyres, etc.). (4) Axle-boxes, also known as lubricating or grease-boxes, and parts thereof (e.g., axle-box bodies). (5) All types of brake gear, including : (a) Hand-brakes, controlled directly from each individual vehicle (lever and screw brakes). (b) Continuous brakes with a single control for all the vehicles of the train. These include compressed air and vacuum brakes. (c) Parts of brake gear including shoes, cylinders, levers, etc. (6) Buffers. (7) Coupling gear (e.g., hook, screw or chain type, draft gears); some coupling devices may be automatic. (8) Frames and parts thereof (longerons, cross-girders, axle-box guides, etc.); frames cast in one piece. (9) Corridor connections and connecting platforms. (10) Bodies (not mounted on underframes) for motorised or non-self-propelled railway or tramway rolling-stock (e.g., for coaches, trucks, wagons, etc.); parts of such bodies (e.g., coach or truck doors, partitions, hinged sides of wagons, side stanchions, running boards, water tanks for tenders). (11) Pipes with coupling heads for the braking or heating systems. (12) Hydraulic shock absorbers for bogies. It should be noted, however, that angles, shapes, sections, sheets, plates and other parts of frames, and also tubes and pipes, etc., of base metal, remain classified in Section XV unless they have been worked to such an extent that they are clearly identifiable as parts of locomotives or rolling-stock.
