Resident Engineer (NSW) McKenzie & Holland (Australia)

The latest review published in the Proceedings of the Institution of Electrical Engineers, U.K,, indicates that conversion to direct current by means of rectifiers accounts for something like 30% of all the electrical energy generated in the world: and like the latter,it is approximately doubling in volume every ten years.

In recent years, the importance of a modern, efficient, signalling system for the Railways of Great Britain has increased enormously. Since the Nationalisation of the Railway Companies in 1947, the British Railways, or British Rail, as it is now called, has spent over £400 million on the modernisation of its Railway System, to meet the demand for a faster and more economic service.

The signalling system has advanced from being a means of providing safety for the running of the railway, to a point where it is essential for the control of the railway network and although safety is still a basic requirement, the purpose of such a system is to co-ordinate and control1 traffic in the most efficient and economic manner possible.

This paper has tried to outline some of the many developments which have taken place over these years of modernisation and to stress a few of the advantages which may be gained from extensive signalling installations.

Engineer for Communications, Department of Railways NSW

We are all familiar with the visible components of transport - the busy terminals, extensive marshalling yards and a variety of rolling stock, including the latest designs in locomotives which never fail to hold the attention of he public and the admiration of the schoolboy.  Behind the scenes, there is always another story, not quite so colouful, but not less impressive in its contribution to the transport facilities of the State.

AJ Everingham AMIRSE

This paper is entitled "Signalling Installations in New South Wales."  It deals chiefly with the general practice outside the electrified area, and any features peculiar to that section have been omitted, as it is considered that the matter is far too comprehensive to be dealt with in a single paper such as this. However, the matters referred to herein also apply, in the main, to the electrified area.

One of the major problems in Railway working is to provide adequate facilities for Roadways crossing the lines and having provided these facilities, to protect the road user from the consequence of coming into collision with railway vehicles. For many reasons, the problem of avoiding such! accidents has invariably devolved upon the railway authorities.

The obvious solution is to avoid crossings, or where this utopian ideal cannot be attained, to cross the railway by means of overbridges or subways. It will be realised however, that geographical conditions and economic considerations very often render this impossible and so it is found that in a great number of cases the roadway crosses the railway by means of what we know as a level crossing, that is a crossing where the roadway and railway tracks are on the same plane.

A. G. HENRY, MIRSE, AMIE (Aust.), ASTC (Syd.)

Essenital in all forms of human activity are communications.  They are the means by which ideas are conveyed from the mind of one person to the minds of others. Communications are necessary in all associations.  For any unit of society to function - to exist - it must be held together by a bond, and that bond is its communications, adequate to itself.  Communication is a medium through which the ideas of the members in any group are interchanged.  It is these that integrate them into a coherent unit.  It is communication in fact which differentiates between human and static life; between the tree and the animal - the tree cannot communicate with its fellow or among its parts; it is doomed to remain an solitary individual in space. Out of the gradual growth of communications, villages have sprung into towns; towns have become countries; and empires have built up. Now, with the perfection of communications, we move towards the "one world of the visionaries."

Some Observations on English and American Practice

Mr. F. Stewart (Member) A. S. T. C., A. M.I.E. (Aust.) Assoc. Inst. T.,

Signal Engineer, McKenzie & Holland (Aust.) Pty. Ltd.

Modern railway signalling covers such a wide field that no single paper can adequately cover the technicalities involved, and this paper has, therefore, been limited to some observations on English and American practice in power signalling.
Railway systems in England and America have had to meet widelv different conditions of population density and area, and traffic operating conditions in the two countries have been developed to suit the local conditions.
Railway signalling in each country has been adapted to meet the varying traffic conditions and track layout, whilst retain- ing the accepted basic principles of safe working.
We get some idea of these differences by comparing the long hauls on single track, with long and heavy trains, so characteristic of much of the mileage on American railways, with the shorter trains and short hauls on multiple track, which constitute the greater portion of English railways.
