The 1980s have seen a wide range of innovations in rail technology. New technology has often been superceded before it has been acquired. These advances, which have occurred in all disciplines, are listed. Severe demands on track have led to the development of wear-resistant grades of steel and the use of the plasser and theurer dynamic track stabiliser to consolidate newly laid track. Development of the gate turn-off thyristor has favoured the use of three-phase drive with ac motors which is expected to be particularly useful for dealing with london's growing commuter traffic. A similar high power drive will be used on channel tunnel international services. The networker vehicles being introduced by network South East are 10% faster, carry 10% more passengers and are 25% cheaper to operate. Details are given of developments in the reduction of floor height and the use of independent wheels. The widespread use of solid state interlocking (ssi) and automatic train protection (atp) are described. Passenger information can be displayed by led, liquid crystal, flip dot or flap board and a new development is liquid crystal for use in sunlight. Poster production has been updated and audio-visual information will be triggered by beacon on tubes. The importance of on-train diagnostics and the possibility of using fibre-optic cable are discussed.
