86.03 - Self- ropelled railway or tramway coaches, vans and trucks, other than those of hea ing 86.04. &' - Powered from an external source of electricity 8603.90 - Other 8603.10 Self-propelled railway or tramway coaches, addition to being equipped with a power freight. These vehicles may be designed vehlcles of the same type, or to one or more differ from locomotives because, in also desi ed to carry passengers or or to e coupled to one or more f? The main feature of these vehicles is that they are fitted with a control cab either at one or both ends, or in a raised position (conning-tower) in the middle. The various types of self-propelled coaches, vans and trucks falling in the heading include : (A) EIectrically-propelled coaches in which electrical ener is received fiom a stationary external source, e. through a antograph or trolley in e case of an overhead cable, or through collector sties mounte on the bogies in the case of a third rail. P Tramway coaches. These sometimes use two conductor rails placed in a slot rail and current is collected via a special device known as a " plough ". (3)Rail-cars, i.e., self-contained vehicles running under their own power and equipped with diesel or other internal combustion engines, etc. Some rail-cars are fitted with solid or pneumatic tyres and others are of the rack-rail type. (C) Self-propelled vehicles functioning by means of storage batteries. This heading also includes electro-gyro rail vehicles. The princi le of this system is based on the accumulation of kinetic energy in a fast revolving fl heel. ~ f i energy s is then by means of an electric generator transmitted to a driving motor m t e form of electric current. The scope of this system is rather limited, but it may be applied in light rail-cars or in trams. It should be noted that the heading excludes road motor-coaches convertible into rail-cars simply by changing the wheels and locking the steering, the motor remaining unchanged (heading 87.02). K"
1.- This Chapter does not cover : (a) Railway or tramway sleepers of wood or of concrete, or concrete guide-track sections for hovertrains (heading 44.06 or 68.10); (b) Railway or tramway track construction material of iron or steel of heading 73.02; or (c) Electrical signalling, safety or traffic control equipment of heading 85.30. 2.- Heading 86.07 applies, inter alia, to : (a) Axles, wheels, wheel sets (running gear), metal tyres, hoops and hubs and other parts of wheels; (b) Frames, underframes, bogies and bissel-bogies; (c) Axle boxes; brake gear; (d) Buffers for rolling-stock; hooks and other coupling gear and corridor connections; (e) Coachwork. 3.- Subject to the provisions of Note 1 above, heading 86.08 applies, inter alia, to : (a) Assembled track, turntables, platform buffers, loading gauges; (b) Semaphores, mechanical signal discs, level crossing control gear, signal and point controls, and other mechanical (including electro-mechanical) signalling, safety or traffic control equipment, whether or not fitted for electric lighting, for railways, tramways, roads, inland waterways, parking facilities, port installations or airfields.
