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.

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 cablenetworks of various types.

R Hogan Westrail The narrow gauge hump yard within the Forrestfield Marshalling Yard occupies virtually the whole western side of the entire complex, extending 3.2h having a maximum width of 200m and covering an area of approximately 85 hectare overall. The standard gauge yard is on the east and all operational and service facilities shared between the two gauges are in a strip along the centre of the yard. The Hump Yard marshalls all loads for country destinations which were previously done at Midland, Perth Central, East Perth and Fremantle yards and block marshalls loads for metropolitan delivery points.

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."
