|2008 - July - Brearley - Improving Skills to Improve Efficiency|
Les Brearley BE (Elect), Grad Dip Bus, RPEQ, HonFIRSE
Ansaldo STS Australia
Effective training is an essential element in improving delivery efficiencies. This paper will look at three facets of the impact of training on the delivery of business outcomes. The first is the fundamental issue that if staff do not have the required skills they will not be able to produce the outputs. It follows that if skill levels are increased then flexibility and efficiency will be increased. The second facet is completing the right training. The actual training needs must be determined and training developed and delivered such that the skill gaps are filled effectively at the appropriate time. The third facet is how the training is delivered. There are a range of delivery options available from traditional classrooms and face to face raining to online training and assessments. Using the most effective option for particular situations will improve skill transfer with fewer resources required for both trainers and trainees.
|2008 - July - Automated Signalling Design - A Feasibility Study|
Aaron Fraser BSc, BEng, Post.Grad.Dip RailSig, S.I.R.S.E.
This paper documents the proposed development of new automated signalling design tools to facilitate improvement in the current design lifecycle for Ansaldo STS. The project was undertaken as part of the CQU Postgraduate Diploma in Railway Signalling – CPD6 Signalling Research Project. It investigates methods of automating signalling design for the Ansaldo STS Brisbane signalling design office and the benefits of these tools to the company. The design methodology for a typical QR Regional signalling project forms the basis of the research. The project has determined four tools to assist in the production of signalling design: the Bid Tool for generating cost estimations for signalling works; the Drawings Tool for generating circuits; the Microlok II Design Tool for generating Application Logic; and the V&V Tool for automatically validating and verifying the system against safe Signalling Principles. This paper discusses the goals of the project, the project methodology, major findings, and recommendations for Ansaldo STS and all signalling design companies.

|2007 - Oct - Murphy - The Application of ERTMS/ETCS System|
Eddie Murphy HND Engineering, MIRSE
Westinghouse Rail Systems Australia
It is timely to provide an update about ERTMS/ETCS given that there is a trial application currently in progress with RailCorp in NSW and other states have also shown considerable interest. Though the ERTMS/ETCS system is well defined and enables interoperability of trackside and onboard technologies from different suppliers, there are some critical high level and many detailed application decisions that will impact on the railway network once the system is in service. Some of the main factors to be considered when applying ERTMS/ETCS into a railway network are:
• Network rules and procedures including safeworking
Many of the rail networks in Australia currently employ simple Train Protection technology e.g. trainstops, AWS and TPWS or in some cases have no train protection at all. It is a big step to go from this to a full cab signalling system that will fundamentally alter the way the system is operated. Railway organisations will therefore need to involve all stakeholders in the decision making process including Corporate Safety, Safeworking, Train Operations, Train Crewing, Drivers, Train Control, Engineering Standards, Rolling Stock and Signalling Maintenance and future capacity planning.

|2007 - March - Page - Windah - Grantleigh - Coal Line Capacity Improvements|
Charles Page BSc. Elec/Electron, MBA, FIRSE
Director of Marketing & Sales Westinghouse Rail Systems Australia
The Windah-Grantleigh project arose out of Queensland Rail's strategic planning process that identified line capacity improvements required in the Blackwater system in Central Queensland. It was the first in a series of such projects conducted under a new contract model, designed to deliver cost effective and high quality upgrades in the minimum possible time in a collaborative environment. The Windah-Grantleigh was successfully delivered in a very challenging timescale and included a number of novel technical features. In particular, it was the first Australian application of the WESTRACE WNC in a hot standby configuration.
|2007 - March - Godber - Fundamentals of Signalling a Heavy Haul Railway|
Anthony Godber BSc(Eng), CEng, MIET, MIRSE
Signalling of any railway aims to meet the often conflicting demands of safety and operational efficiency in the most cost-effective manner possible. Heavy haul railways have some very different requirements to passenger and mixed traffic routes. Using the Pilbara Iron network in the remote north-west of Western Australia as an example, this paper traces the path from operational requirement to the layout and operation of the track and signalling. With long trains and high axle loads, the ability to maintain the railway also creates specific infrastructure configuration and capacity requirements.
Some more recent challenges arising from the need to substantially increase the capacity of the railway are also discussed. The ability to build, test and commission additional facilities while continuing to meet the existing schedule is now a major consideration.

|2007 - March - Baayens - Asset Protection for Heavy Haul Railway|
Written by A.Baayens Technical Officer
Union Switch & Signa
Heavy Haul Railways are often owned and operated by bulk commodity producers. Their rail operators are focused mainly on production. Although profit, costs, growth and sustainability are important to the operators, they will be focused and measured daily on productivity which can be simply described as, the number of tonnes of product actually delivered versus the planned tonnes. In boom times operators will be striving to increase planned tonnes and to do this cycle times must be reduced or more train consists operated.
The railway is part of a production process. Although not productive in itself, it is necessary for the transport of the bulk product typically between the mine and port. Rail is usually the most efficient means of transporting bulk product over long distances.
The railway adds to the unit cost of the product. The factors that affect the unit cost of the product by rail are:
· Train crewing costs
As the railway adds cost to the production process it is continuously under scrutiny to minimise costs wherever possible.
Railways must minimise the cost of railing bulk product and safeguard production against delay and losses. It is vital for the production process to have a continuous flow of product for maximum efficiency and minimal cost. If the flow of traffic on a finely tuned railway is stopped an immediate loss is incurred. It is vital therefore to either anticipate and prevent the cause of disruption, or be able identify and respond immediately to the cause of the disruption.

|2007 - July - Weerakody - Innovative Project Delivery Solutions|
Don Weerakody MIRSE, MIEAust, MIET
Public Transport Authority
This paper outlines two signalling projects recently undertaken by the Public Transport Authority of Western Australia (PTA). Each of these projects dealt with unusual circumstances, resulting from acts of vandalism. They both required innovative solutions as the approaches normally employed were unsuitable.
The Boom Gate Motor Protection Project is a solution to level crossing failures caused by vandals hanging on the boom arms at level crossings as they are returning to the upright position. This causes the boom motor to trip and the boom remains in the down position. The crossing remains in this state for some time or until a technician arrives and resets the boom motor circuit breaker. This leads to prolonged closure of the level crossing and encourages motorists to drive around the boom gates. This project addresses this problem, and also allows provision of other features such as enhanced monitoring of the level crossing equipment.
The Track-Based Transmission System for Signalling Project was implemented due to the theft of aerial line circuitry over a 5.5km section of track between Armadale and Mundijong. Direct replacement of the existing signalling infrastructure was not possible due to damage to the poles and the unavailability of appropriate aerial line cable in a short space of time. The railway reserve for this section also falls under the protection of state and federal environmental protection legislation enacted after the original installation of the signalling equipment. Re-instatement of the existing system using cables would have caused an unacceptable impact to the local ecology due to the trenching required.
The Boom Gate Motor Protection is in operation at two level crossings and is being progressively installed at all urban level crossings. The Track-Based Transmission System for Signalling is successfully in operation on the Armadale to Mundijong railway.
|2007 - July - Webb - Optical Fibre for Freight Railways : Or How A Radio Communications Engineer Saw the Light|
John Webb BE (Elec), MIEAust
Telecommunications companies have been using Optical Fibre for many years. So why did it take those of us in the Railway community in Western Australia so long to see the light? As often happens in Engineering, it takes time before a good idea can become a good Engineering solution.
This paper describes how optical fibre became an integral part of Rio Tinto's Pilbara Iron Railway Operations.
|2007 - July - Samaan -A Position Paper on Software Validation and Dependability for Safety Critical Systems|
Noel Samaan, PhD Senior Member IEEE (USA), Member IEE (UK), CPEng
R&D Software Systems Group Ansaldo STS
As the reliance on software is significantly increasing in railway industries replacing electronic, pseudoprogrammable electromechanical devices and wayside signals (in the future), the demand for quantifiable and traceable techniques to determine the trustability and dependability of software is becoming more critical. Given the pressures on delivering projects on-time with inherent heavier contribution of software to decision– making dynamics of train operations whether related to train control, routing, database-driven scheduling or issuance of train orders and, given the rather fluidic nature of software development and change in requirements (when compared with hardware domain), validation of software applications for railway at relatively high confidence levels and low cost is a challenge that has become a significant ingredient to project over-run and higher than estimated project costs.
This paper reviews the requirements for safety-critical systems for railway, highlights the main differences between software and hardware approaches used to determine product reliability and presents a case study to illustrate how modelling and metric-driven approaches to software validation can lead to high assurance levels whilst reducing the validation cost. The paper concludes with a few recommendations where railway industry can benefit from other industries where software became a core activity at later stages of business evolution which demanded the delivery of faster, cheaper and better quality software applications.
|2007 - July - Bilston - Design Development of Communications System for the Pilbara Iron Ore and Infrastructure Project|
Simon Bilston B Eng, MIEAust
Ansaldo STS Australia Pty Ltd (Formerly Union Switch & Signal)
This paper will discuss, as a case study, the design development for the communications system design as undertaken by Ansaldo STS Australia (formerly known as Union Switch & Signal) that will support the Pilbara Iron Ore and Infrastructure Project. This project includes a railway between Port Hedland and Cloud Break mine in the Pilbara region of WA to be constructed for The Pilbara Infrastructure (a subsidiary of the Fortescue Metals Group). Included will be a review of the preliminary project history and the base requirements for the system, followed by discussion on the key processes used to accelerate the decision making process and finally a summary of the key systems presented in the Preliminary Design Report for the communications system.
Ansaldo STS Australia assisted The Pilbara Infrastructure in the initial feasibility process that resulted in a number of important 'directions' that the design was to take in order to minimise TPI's exposure to project and cost risk. The two main directions taken were for the use of microwave radio over an optic fibre solution for the backhaul communications and the use of an analogue voice radio system over a digital system.
The process of "Integrated Project Teams" was utilised to fast track the resolution of key design decisions. The process provided a valuable method for both Ansaldo STS Australia and The Pilbara Infrastructure to quickly explore and agree on a direction when faced with key technical decisions. The process was largely successful with a few noted improvements that will be applied to future projects completed by the Ansaldo STS Australia communications team.
The resultant Preliminary Design Report for the communications system is biased toward robust, proven technical solutions that are fit for purpose and will provide the railway with reliable support for operations both during important initial stages and into the future.
|2007 - July - McCluskey - WestNet Rail - Building Resilience and Redundancy into a Centralised Train Control System|
Phil McCluskey B App Sc (Eng)
Project Manager Train Control Centralisation Australasian Railway Consultancy Services
WestNet Rail is in the process of centralising its Train Control Operations in Western Australia. Given the strategic importance of the new facility, a significant effort has gone into ensuring that the new system utilises high level resilience and redundancy strategies, whilst maintaining a flexible platform for business needs. This paper describes how this was achieved in an environment of high technical and commercial risks, tight timeframes and constrained resources.
|2007 - July -Eyre - Signalling of the Southern Suburbs Railway|
Paul Eyre Project Manager
Ansaldo STS / Union Switch & Signal Pty Ltd
The 71 km extension of the Perth electrified rail network from Perth through to Mandurah, commonly referred to as the Southern Suburbs Railway (SSR), commenced in 2003 and is due for completion towards the end of 2007. The SSR project is divided into several packages, namely A-G, involving numerous engineering disciplines and various contractor skill sets.
Package "A" comprises all new railway infrastructure including earthworks, track and traction overhead works (except for the new bored tunnel and associated systems constructed by Package "F") and all the signalling and communication works. Packages "B", "C" & "D" cover the construction of 8 new stations.
Package "E" covers alterations done by Mainroads WA to the Kwinana Freeway to accommodate the new railway line in the median from Perth to Thomas Road. Package "G" covers the train control works for the SSR.
Package "A" main contractor and electrical systems subcontractor (Rail Link Joint Venture and ODG) employed Ansaldo STS to do the signalling system design, procurement of all signalling equipment, and testing and commissioning of the signalling system from Perth to Mandurah including the section through the bored tunnel section. Installation of the signalling equipment and "setting to work" were excluded.
Package "G" main contractor is Ansaldo STS. Package "G" comprises replacement of the original system installed in 1989 when Perth was electrified by a new Phoenix Train Control System, and responsibility for the design, implementation and testing of modifications to the Phoenix Train Control System to incorporate the new Mandurah line, and design and supply of the Customer Information System for both the new and existing network.
The construction of the SSR will be introducing new systems architecture, technology and practices to that previously used by the Public Transport Authority of Western Australia (PTA), the owner and operator of the Perth rail network. This paper identifies some of these innovations, and addresses challenges faced by Ansaldo STS to complete their works under Packages "A" & "G".
