2004 – October – Drew – National Standard for Health Assessment of Rail Safety Workers

Author(s):
Date presented: December 27th, 2015

Dr Tim Drew MBBS Work Health Clinic - Mile End New Medical Standards for Rail Safety Workers were adopted across all Australian States and Territories as of 1 July 2004. The new standard represents a significant step in the improvement of rail safety and is the first time a common system of health assessment has existed across all Australian jurisdictions. The new standard adopts a risk management approach and reflects contemporary best practice in assessing the health of rail safety workers. The standard is a result of extensive research and input from a wide range of government, industry and medical stakeholders and although initially developed for Victoria was modified and then mandated for application across all Australian jurisdictions following on from recent rail accident investigations. In this paper we will examine the genesis of the standard, its make-up with a particular focus on "Risk Mitigation" strategies and finally the obligations of employers, employees and medical practitioners in the implementation of the standard.

2008 – Nov – McQueen – Setting the Scene – Projects DART & Electrification

Author(s):
Date presented: December 27th, 2015

Phil McQueen BE (Hons), CPEng, MIPENZ, AMIRSE ONTRACK (NZ Railways Corporation) This paper describes the two major rail infrastructure projects currently underway on the Auckland Metropolitan Rail Network (AMRN): Project Develop Auckland's Rail Transport (DART) and the Auckland Electrification Project (AEP). Both are part of an overall rail upgrade that includes provision of improved station and passenger facilities and provision of a new fleet of electric trains. The scale of the projects has not been seen in rail in New Zealand for over 20 years and is placing demands on resourcing as well as causing service impacts during construction. However, both are immensely positive developments for rail in New Zealand, and in Auckland in particular. This paper briefly outlines each project, its current status, and challenges with resourcing and construction.

2007 – March – Wardrop & Caldwell – Application of Problem Space Search to Heavy Haul Scheduling and Infrastructure Planning

Author(s):
Date presented: December 27th, 2015

Alex Wardrop BSc (Hons) MEngSciDavid Caldwell BEng (Hons) WorleyParsons Rail Developing train plans for heavy-haul railways is a complex task. Australia's heavy-haul lines are predominantly single track, presenting the particular problem of how to cross and pass trains to maximise capacity and minimise delays. Timetabling by manual techniques is time consuming and is unlikely to provide an optimal train plan. The Problem Space Search technique allows many thousands of feasible timetables to be rapidly developed and then ranked according to performance against such measures as throughput, average delay per train and cost. This produces a timetable that can be regarded as optimal under the prevailing conditions. This has an obvious application for making the timetabling process faster, reducing delays, and increasing capacity. However, this rapid generation of timetables enables timetable development to be undertaken on an experimental basis for strategic planning purposes, and this is perhaps a more significant application. Different combinations of infrastructure improvements, train configurations and timetables can be examined for their ability to sustain projected traffic requirements. The Problem Space Search technique has been applied to software utilised by BHP Billiton for integrated railway scheduling, and by ARTC for infrastructure planning.

2002 – August – Karrasch Organising an IRSE Exam Study Group

Author(s):
Date presented: December 27th, 2015

Sandra Karrasch BE (Electrical) AMIRSE Signal Engineer QR The study group formed to provide training for the IRSE exam so that signalling engineers can gain the credentials of passing the exam. The group organised lessons and tutorials for modules 1 & 2 in the first year and modules 3,5 & 7 in the second year. Many people supported the study group, including QR management, IRSE senior members and the IRSE Qld section. It was found that having smaller classes and holding the lessons as tutorials rather than formal lectures were often of greater benefit to the participants as there was improved interaction with the presenter. It was noted though that some subjects worked better as lectures. Encouraging exam candidates to debate answers to past exam questions was also beneficial. This enabled the candidates to discuss their answers, work out the differences and examine different solutions to questions by the sharing of knowledge. The main benefits to QR have been the collection of information and imparting of knowledge from senior engineers. Other benefits include better-trained signal engineers and an awareness of the wider issues of safety in signalling systems.

2006 – July – Caldwell – Generation of Optimised Automatic Signalling Layouts with Computer Simulations

Author(s):
Date presented: December 27th, 2015

David Caldwell BE (Hons) WorleyParsons TMG This paper discusses the application of computer simulations to optimising the layout of signals operating on the Automatic Block principle. Considerable efficiencies can be achieved in signal design and capacity analysis by methodically applying computer simulation tools. A system for quickly and accurately testing the influence of variables (such as train types, dwell times and speed limits) on track capacity and their interrelation with signal placement is proposed. The aim of the layout is discussed in the context of either maximising line capacity or optimising the layout to a specific traffic requirement. Application of existing simulation tools is explained and weaknesses are discussed. There is a complex interaction between braking distance, signal spacing and clearance times, particularly under diverse traffic conditions. A method for analysing these interactions quickly and efficiently is suggested. A method of laying out signals for maximum unrestricted line capacity is also discussed.

2000 – July – Martinovich – Extenson to Perth Suburban Rail System

Author(s):
Date presented: December 27th, 2015

M P Martinovich Project Manager Perth Urban Rail Development Department of Transport Public transport accounts for 3% of inter-suburban journeys and 35% of peak hour trips to the Perth Central Area. Of all trips in the Perth Metropolitan Area, the public transport share is around 6%. A primary objective of the Department of Transport's Metropolitan Transport Strategy (MTS) is to significantly increase the number of people who use public transport. The MTS has set the following targets: to increase the public transport share of intersuburban trips from 6% to 12.5% by 2029; and to increase the public transport share of peak hour trips to the Perth Central Area from 35% to 50% by the year 2010, rising to 65% by 2029. The above requires an integrated public transport system which will complement, and provide a viable alternative to private car usage on major trunk routes. There is also a growing concern with regard to the air quality of the Perth Metropolitan Region, as detailed in the Air Quality Management For Perth, which highlights that private car travel is a significant contributor to degradation of air quality in the Metropolitan region.

2006 – July – Sundareswaran – VPI Application with Radio Links

Author(s):
Date presented: December 27th, 2015

Kaniyur Sundareswaran B.S. {Engg.Tech.}, M.S. {Soft. Sys.}, C.Eng., MIET, MIRSE United Group Infrastructure United Group Infrastructure have commissioned an ALSTOM Vital Processor Interlocking (VPI) system using radio links for transmission of vital signalling information, between two VPIs, each installed at either end of the Kinalung crossing loop, on the Parkes to Broken Hill line. This project is part of a contract with Australian Rail Track Corporation (ARTC) for extending the crossing loops at Kinalung and Matakana, each crossing loop being extended to 1850 metres in length. This paper describes the VPI architecture employed in Kinalung and its interfaces to the radio link. It explains the basic components of a VPI system and its configuration for the Kinalung crossing loop. The paper also covers the type of radio system used for this communication, its configuration parameters and explores how a non-vital radio system could be used to communicate safely.
