Transport

Architects and Designers: Arcon ◦ Theme Direction: George Williams

It might have been enough if this small island had bred only the pioneers of modern transport by sea; but, in fact, it produced also the pioneers of railways, of aeronautics and, to a large extent, of road vehicles and bridging as well. It is these four methods of travel and transport – rail, road, sea and air – that provide the substance of the four main sections of this Pavilion.

Running like a spinal column through all four floors of the building is the story of communications. Communications are the lifeline of modern transport. For this reason the exhibits showing British contributions to telegraphy, telephony, and all forms of radio are show close to the displays of the transport which they serve.

Communications

Theme Convener: Geoffrey W. Hart

Yet another means of communication is the spoken and written word. Books and printing are given due attention as a separate exhibition in South Kensington. Here, in the fifth section of the “Transport” Pavilion, we are concerned with the transmission of thought and information by postal and electric means. They fit intimately into the narrative of the whole Pavilion, because telephone, telegraph, radio and radar together form an essential service for all modern transport. Closely related with these services in technique are sound and television broadcasting. These, too, are displayed here.

Mails

In the establishment of modern postal systems we were the pioneers and, since then, we have developed them to their present state in which all forms of transport are employed. The Post Office Underground Railway, demonstrated in the Railway section, stands as an example of lessons learned from passenger transport being applied to the carriage of mails.

Adhesive postage stamps were invented in England by Rowland Hill in 1840. One example here of modem stamp designing and printing is provided by the special series produced to commemorate the Festival of Britain.

Telecommunications

The British discoveries which led to the electric telegraph are shown in the Dome. Here, the displays begin with their early applications through the inventions of such men as Cooke and Wheatstone in 1837, and culminate in working examples of the most advanced teleprinting machines now being used. Pictures are also sent by telegraphy. Here you can see some of them being received over Cable and Wireless circuits from the other side of the world.

Telegraphy and telephony depend just as much on the wires that carry the current as on the terminal equipment. The most difficult problems arose when it came to laying them under water. Perhaps the greatest landmark in past development was the completion of the first successful Atlantic cable in 1866. Of recent advances the most remarkable is the production of the submarine repeater – an amplifier which runs for years without attention on the bed of the sea.

The present-day British cable system is a net around the world, physically linking the countries of the Commonwealth, and many others besides.

Early developments in the telephone were chiefly due to Alexander Graham Bell, a Scotsman who lived and worked in America. Admittedly, the British were slow in following them up, but our modern telephone service has a number of achievements to its credit. One of these is the unattended automatic telephone exchange used in the more remote country districts.

Radio Communication

20160315 71In discovering the principles of radio and in their application this country has played an outstanding part. The basic discoveries are shown in the Dome, in this section we are more concerned with the development of radio to the indispensable position it now holds, as a service for all manner of activities. It is still a peculiarly live subject, in which important advances occur almost yearly. The display in this section shows some of the newest techniques used. They vary from the passing of large numbers of messages on point-to-point services, to police work, where radio is now established as a primary aid.

Radio, as the principal means by which ships and aircraft now maintain contact with their bases, is displayed on the first floor of this section together with other radio aids to navigation. It is, of course, the chief method used nowadays for operating ships and aircraft, for passing weather and distress information, and for telling them their exact position at sea or in the air.

Radio Aids to Navigation

Drake’s Spanish adversaries believed that he had a magic mirror in which he could see the dispositions of their fleet. It has taken us nearly four hundred years since then to make such a device, but now we have it. It is radar – a method of seeing by means of radio waves.

British scientists developed radar in the first instance to meet a military need, but now it is being freely applied for civil purposes. This section shows how it is used for supervising aircraft from the ground, or vessels from the shore, and how it aids the navigation of aircraft and ships whether in daylight, darkness or fog.

To illustrate the use of harbour radar, a modern equipment is working in the Pavilion. It covers the Thames in the neighbourhood of the Exhibition, showing the visitor the passage of craft which he cannot see directly with his eyes.

Sound Broadcasting and Recording

The importance of sound broadcasting as a world-wide medium of communication is illustrated in the “Land” section of the Dome of Discovery. Here, on the top floor of the “Transport” Pavilion, the displays relate more particularly to modern receiving equipment, both for specialist purposes and for general listening. It is shown, too, what is being done in this country to overcome the great problem of modern broadcasting – the difficulty of fitting the large number of programmes demanded into the relatively narrow band of frequencies that is available.

The demonstrations here also illustrate the high quality of sound reproduction of which modern equipment is now capable.

Television

The science of sending moving pictures by radio is largely an international one, but, like many other electrical developments of the last fifty years, it stems from the original discoveries of Sir J. J. Thomson.

Britain was the first country to institute a public high-definition television service. It started in 1936, and the standards laid down at that time are still in successful use to-day. The British system is still the best compromise between cost and performance for black and white television. Nevertheless, British manufacturers are making television equipment suitable for any of the systems used by other countries.

Television as a medium of entertainment is displayed in its own Pavilion on the other side of Hungerford Bridge. Here, in the “Transport” Pavilion, the displays are concerned more with modern technical developments and problems of a young and rapidly growing means of communication for which many new applications are already apparent. Here are examples of really up-to-date technical and scientific endeavour in a subject of which we all have some personal experience.
