AM Hambleton BE

Austral Standard Cables Pty Limited

The need for protection of cables against the ingress of moisture has long been a problem in the communication industry. Moisture entering cables may produce direct faults at the point of entry or may travel along the cable producing faults at remote points. Essentially the sheath of the cable has as its basic task the protection of the con- ductors or core from the effects of moisture, but, as is well known, various faults may occur from time to time whereby the sheath is dam- aged or becomes permeable to water and is therefore ineffective in protecting the cable core. As a means of overcoming this problem,
many solutions have been suggested, ranging from the completely filled cable, where the conductors are surrounded by a petroleum jelly sub- stance, to the high security plastic insulation currently being used in Australia where the effect of water on the conductors is minimised. However, problems in manufacture and in the construction of joints currently in use makes both of.these techniques slightly inadequate, and therefore a third technique using a pressurized cable and joint is gaining popularity. This paper deals with the application of gas pressurization systems to communication cables of both lead sheathed and plastic sheathed construction. It is the intention to describe techniques currently being used with success in communication cable
networks of various types.

The State Government, recognising the increasing hazards to road users at level crossings diie to the day by day increase in the number of road vehicles, improvements to roads generally, and the consequent increased speed of vehicles, decided that in order to deal with the problem of improving conditions at level crossings in a practical manner and to ensure that any expenditure in connection with improvement was shared equitably with the various interests in the community, set up in February, 1960, a Special Level Crossing Fund for the purpose of financing initially the alteration, improvement or replacement of facilities at railway level crossings, or for the elimination of crossings where justified and an Inter-Departmental Level Crossing Committee comprising of representatives of the Department for Railways, Main Roads, Public Works, Local Government and the Treasury has been set up to recommend to the Minister for Transport, works which it is considered should be carried out,

In this paper I intend to outline very briefly the history of Level Crossing Protection in Victoria and to describe some of the control problems and principal technical features of the design of flashing light signals and half-boom barriers with flashing light signals (later reffed to as boom barriers).

Legislation in the United Kingdom requires the Railways to protect the road user at rail-road level crossings.  In the United States of America legislation requires the road user not to cross the rail unless he can do so safely.

In Victoria, the Birtish practice of protecting level crossings was used in cities nd towns.  Today, of the crossings in the Melbourne Suburban Electrified Area, approximately 200 are portected and only about ten are not protected.

EC Wooderson AMIE Aust

Assistant to Eng Sig & Int QGR

The basic requirement of level crossing protection from the railway point of view is:

  • Protect trains from possible derailment due to collision with road vehicles which can be up to 20-30 tons.
  • Protect road vehicles and users from damage by collision thus precluding damage or loss claims.

Therefore the protection device provided should be governed by the following financial aspect:

  • Possible costs of damage to railway equipment, and loss of revenue due to disruption of service.
  • Costs of court action promoted by injured parties.

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.

pdf.png 1966 - July - Adamson - Modern Trends in Railway Signalling


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.
