The total route length of KTMB’s network amounts to approximately 1670 km and is mainly single track except for about 150 km of electrified double track sections around the capital city, Kuala Lumpur, for commuter services.
JT Skilton Signalling systems within Tranz Rail which require control from a remote location can be classified into three types, Centralised Traffic Control (CTC), remote controlled interlockings in Track Warrant (TW) territory and remote controlled interlockings embedded in Double Line Automatic (DLA) signalling. The CTC systems control the movement of trains in both directions over a single line section divided up into block sections and crossing loops. A field unit is installed at each crossing loop for the purpose of communicating with the control centre. TW control requires all trains to hold a warrant for the section of line being traversed. This warrant is issued to the locomotive engineer verbally over the train radio system and checked for correct reception by reading back over the radio system to the control centre. A selected number of crossing loops within TW territory are fully interlocked and equipped with a field unit which allows the Train Control Operator (TCO) to have full control over motor points and signals. Centralised control of interlockings in DLA territory is used where junctions between main and branch lines occur. Central control is used for movements to and from the branch line and, although it can also be used for signalling along the main lines, the interlocking can be switched to automatic for main line movements.
Wayne McDonald Computer based interlockings today must be adaptable to the vastly different environments found in the many rail networks throughout the world. This paper overviews some of these environments where one such system, WESTRACE, has been installed and it highlights some of the special requirements essential to suit those locations.
Peter Brock, Frank Ebzery & Bruce McMurtrie The construction of the Year 2000 Olympic facilities and the relocation of the Royal Agricultural Show Grounds Homebush Bay requires the construction of a high capacity transport link. Heavy rail is the only transport system that will supply the required capacity. The new Homebush Bay rail Loop will connect Olympic Park and the new Homebush Bay Showgrounds with the rest of the Sydney metropolitan rail networkTrail loop is nearing completion and will be commissioned on the 22/23 November 1997.
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.
AW Wardrop Research Officer, NSWGR The following discussions relate to two aspects of a computer simulation model developed for NSWGR by members of its Research and Development Section. The model called DTRAIN/STRAIN carries out train performance calculations and train interaction calculations for any type of motive power and for a large number of consecutive trains over a common section of track. The two functions are separately discussed here and the verification procedures outlined for each. No attempt will be given as to the types of uses to which such a model can be put in the body of the discussions so it might be best to suggest some here: vetting changes in timetalbes for existing trains and routes examinng performance of new rolling stock examineg the effect on new and existing rolling stock of new routes vetting the performance of existing signalling systems use as a planning tool for new signlling systems.
B.P. Tumalty FIRSE The title of the Paper to be presented, clearly means that the contents will be subjective, the intention is to review the major stages of contracting with particular reference to items which currently tend to present barriers to good contractual relationships. The objective being to utilise the opportunity afforded by the 1 . R - S . E . for a better understanding of the problems encountered and hopefully improved performances which will enhance the status of the signalling and communication engineer in the Australian Railway Industry.
P Gobetz-JC-M,H,A. BE (Electronics), BA, MIRSE The final implementation of the Adelaide Yard Resignalling will be undertaken as part of Contract 100. The scope of this contract covers the work in the Adelaide Yard area and extends 2.2 km on the Gawler line and along the quadruple lines to Goodwood, about 6 km from Adelaide Station.Since the original study the developemnt of computerised interlockings had reached the stage where this option was included in the tender.
R. M. WALLACE Co-Ordlnator E Ackninlstrator Non-Urban Radio V/Line. There Is ample evidence to suggest that the danlnant factor affectlng V/Linets current marketperformance is Its perceived Inability to provide consistently reliable service. This has led to the loss of existing freight and passenger traffic as well as lost opportunities to gain sigilficant new business. The timekeeping perfonnance of many malnltne frelght and passenger servlces in relation to the standards laid down normal schedules is clearly far from satisfactory. Experience on other rail systems both locally and overseas, has shown that the selectlve application of radio to train working has the potential to slgnificantly improve this situation on those trains or mutes where operating problems are greatest.
