NORIHIRO ISHII Deputy General Manager

Yoshikazu Saito Engineer


Railway safety can be said to be a history of troubleshooting.

And the world has come to require railways to reinforce convenience and service quality while looking safety as a matter of course. In such circumstances, midsize cities and the suburban areas of large cities are faced with transportation difficulty that demand is not so great as to require railway but cannot be dealt with only by busses and other automobiles. As a new transit system like AGT (Automated Guide way Transit) that is safe and can meet such demand, has been introduced to play an important role in such regions.

This paper analyzes the technical trend of signaling system and introduces the newest signaling system that was applied to Singapore Sengkang/Punggol LRT, or an advanced AGT.

Rajendra Jadhav B Eng, MBA, AMIRSE

Bombardier Transportation

This paper provides an overview of the Bombardier* CITYFLO* 450/650 Communication Based Train Control (CBTC) systems. CITYFLO 450/650 are emerging as the leading technologies, which were recently selected as the preferred train control in major systems such as the Neihu Rapid Transit system in Taiwan, the Yong-In LRT system in South Korea and Madrid Metro's Lines 1 and 6 in Spain.

The paper elaborates on specific concepts / definitions that are applied to the moving block CBTC technology and will explain the architecture of the CITYFLO 450/650 systems emphasising the approach taken while conceptualising the design of these systems. The paper also describes some of the special features that make these solutions first in their class.

The paper also discusses the methodology used to satisfy the overlay approach where the operator demands the implementation of a CBTC system on an existing operational or "brownfield" system, without affecting existing operations. It specifically addresses the interesting application of CITYFLO 650 for the Neihu-Muzha lines in Taiwan, which has the unique characteristics of being both greenfield and brownfield with an existing 12-km line and the new 15-km extension, as well as featuring both new and existing rolling stock. The paper describes the Bombardier approach and strategy to achieve implementation with such challenging requirements.

Land Transport Authority, Singapore

and 1 depot. From the HarbourFront, located on the southern part of Singapore, NEL runs towards the north-east, passing through the Central Business District, corridor of Serangoon Road and to the new towns of Hougang, Sengkang and Punggol. The depot is located at Sengkang and serves as the operating company headquarter, stabling yard and operation control centre for both the mainline and depot.

The paper describes the key consideration and engineering requirements for a fully automated driverless system. It gives some insights to the four main core systems, namely, the rolling stock, signaling, communications and integrated supervisory control systems. The successful integration of these four systems is of paramount importance to the successful implementation of a fully automated driverless system. The overview of the four core systems will be discussed.

As NEL is a system with a high level of complexity, the project demands a need to adopt a system approach throughout the design, construction, testing and commissioning phases of all the electrical and mechanical systems. The paper will discuss briefly on the approach taken that led to the successful implementation of the project. The NEL system was opened for revenue service since 20Ih June 2003 and has been consistently achieving a system availability of 99.90%.

pdf.png 2005 - March - Jehan - 150 Years of Passenger Car Development

David Jehan BE (Hons), MBT, MIEAust., CPEng.

Business Development Manager
Passenger Services, Southern Region
EDI Rail

Passenger car design in Australia has evolved from the small wooden four wheel 'dog boxes' of the past to the air conditioned stainless steel trains we now see in various parts of the country.

This paper briefly covers the innovation of Australian passenger car'design as it has progressed over time. Australia has had a very unique network of state based rail systems that have developed differently over the years due to various factors including climate, terrain, rail gauge, loading gauge and politics.

The last decade have seen a great uniformity develop in the freight sector of the rail system, which has been primarily driven by the private sector. However, the development of the passenger sector, particularly suburban passenger vehicles, continues to be unique to the state in which it operates.

Mike Hickey B.E.(Hons) Civil

Grad Dip in P.M. and I.R.F.I.E. Aust

Transport Infrastructure Development Corporation

This paper is a discussion about the disruption to railways, particularly in the northem hemisphere, that falling leaves can cause and the various methods and research (in some cases top secret research) that has occurred in recent times to counteract the negative effects of these falling leaves.

Some of the major problems encountered include: trains slipping on grade, or even zero grade, particularly when starting from stations or signals; longer braking required and station overruns as a result of the longer braking hence lower speeds; loss of trains "on train location" systems and signalling systems; trains proceeding past red signals; wheel bums on rails due to loss of traction and damage to trains due to wheel slippage.

First Presented at the IEE, Savoy Place, London

Look ahead some 25 years: what do you think railways will be like? Recently, many railways have been carrying their largest amount of traffic ever, yet they still have a falling market share, and this shows that society still requires transport to support its economic activities. Much transport depends on oil, a diminishing resource. Rail transport can provide fuel efficiency on trunk routes and electrified railways are less dependent on oil fuel. It is my opinion that railways have much to offer to society in the coming decades. The degree to which railways will achieve such support of society's economic activity depends on two things: an ability to attract investment and an ability to deliver a valued service. For both of these to be achieved railways must improve, both their performance and their image. This improvement depends greatly on control and communication.

Bob Barnard BSc CEng FlEE FlRSE

ALSTOM Transport Ltd (UK)

In September 2004, Britain's Virgin Trains introduced radical new timetables for their West Coast and Cross Country services, with more frequent services and significantly reduced journey times. This was made possible by the use of 200kmlh tilting operation by Virgin's fleets of electric and diesel trains. To mitigate the additional risks that these tilting trains potentially introduced to the rail network, continuous speed supervision and safe switch onloff of tilt was provided by the TASS (Tilt Authorisation and Speed Supervision) system.

TASS was developed by ALSTOM Transport as part of its Virgin Pendolino train contract, with on-board equipment also supplied for the Bombardier Super Voyager diesel trains. TASS uses ERTMS-based onboard equipment to carry out the required functions according to telegrams received from passive Eurobalises on the track.

The 194 sets of on-board equipment and 433 Eurobalises so far installed are enabling around 300,000 kmlweek of tilting operation, giving very rapid experience of the performance of ERTMS equipment in full commercial service.

pdf.png 2005 - March - Allison - 150 Years of NSW Railway Signalling

Warwick Allison FIRSE


When I was first approached to present a signalling paper to celebrate the 150th anniversary of railways in NSW, it was thought that an analysis of the various technologies used could lead to an understanding of what drove the changes. Personalities, politics and opportunities were all important drivers in change. Understanding of why we have what we have is an important element in understanding where we should be going.

While the development of the technology was largely performed overseas, in general the colonies were not averse to adopting it. But it was more than the technologies, and the opportunities. The important consideration of signalling philosophy under pinned how the technology was applied. In some cases this was ad hoc, or simply what someone else had done. In other cases (and particularly in NSW) it was a fresh beginning. The opportunities aligned with the technology and the vision to provide a system that would cater for the long term traffic demand and operation of the railways occurred conjointly with the needs for duplication and later, electrification.

I have tried to tie developments together with the other states to give an overall picture of what was happening at the time. However there is a clear NSW bias, and as this is being presented in NSW 150th rail year, I make no apology for it.

pdf.png 2005 - March - Aitken - From Teletype to Megabyte

John Aitken BE AMIRSE

Aitken & Partners, Consulting Engineers

In October 1877 Bell published construction details of his telephone invention. A NSW Railway engineer, Mr Cracknell built a copy and transmitted words and music by telephone over the telegraph wire from West Maitland to Sydney in December 1877. It was an era of excitement and delight in engineering. Morse code had become a mature technology, voice systems were spreading and soon de Forest's vacuum tube triode was to make amplification possible. Transmission systems were no longer limited in distance and the engineers had visions of linking the continent by telegraph and telephone.

The visions were gradually realised, though not without difficulty and dedication. The work practices of those days would not be considered now'. New engineering problems were found, analysed and solved, as communication systems grew in complexity and expanse. Some of the problems were unique to railways and a few were unique to Australia (at that stage). From these beginnings railway communications have embraced analogue carrier telephony, radio, optical fibre and digital camer systems for radio and cable. Mobrle radio has been implemented for train control, security, maintenance and administration. Some of these developments are described and discussed in this paper.

pdf.png 2005 - Aug - Pore - Presidential Address


It is a real pleasure, and I have to confess that I feel a bit nervous, to be standing here in front of this distinguished assembly, being the fifth non-British IRSE President from the start of our Institution in 1912.

To introduce this new Presidential Year, I should like to make an address that will include 4 parts.

I shall start by giving an overview of my career and experiences, underlining for you all these items that have played some kind of role with rail transport and, as quite a few of you may know, not only with signalling. Most of these steps have probably contributed to my presence here.

I shall then continue with the lessons that I have learnt ... so far.

The third part of the paper itself will propose a vision and views about the future of the profession, and it will include ideas for this IRSE 2005-2006 year. And the address will be concluded by a sort of surprise, preceding my wishes for a fruitful year all together.

pdf.png 2005 - Aug - McDonald - Training to a Specification or How to Ruin a Good Training Course

Wayne McDonald BE (Elec) FIRSE

Westinghouse Signals Australia

Rail authorities include some interesting requirements in specifications for technical training to be deliveres as part of a signalling contract. Few of these have any relevance to the delivery of high quality, competency skills that will aid the participants perform their tasks more efficiently and effectively. Specification often place unreasonable demands on a supplier who has made a huge investment on training. The important facets are often overlooked along with any follow up or effort to improve the training in future.

This paper looks at some of the issues from a Training Provider's view - what works, what doesn't what's reasonable and what adds cost with no value. It offers some suggestions on some of the more important short and long term considerations to maximise your benefit from training.

In particular, it examins the best ways to ruin - and not to ruin - good training.

pdf.png 2005 - Aug - Karrasch - QR Engineering Graduate Programmes

Sandra Karrasch BE (Electrical) Grad Dip Mgt (Technology Mgt) AMIRSE MIEAust

Signal Engineer QR

The purpose of this paper is to highlight the current engineering graduate programs operating in QR, the advantages and disadvantages of the programs, and discuss what qualities a graduate program should encompass.

QR has engineering graduate programs in Signal and Operational Systems, Civil Engineering, Rollingstock Engineering, Telecommunications, and Electrical Engineering.

The main advantages of the rotational graduate programs are that participants gain a variety of skills and experience, and acquire a contact base throughout the organisation and externally.

The main disadvantages are forced relocation of staff to other locations, loss of communication with other graduates and staff, and if the program is not managed well can fail in its operation and in graduate development.

To retain graduates a graduate program should consider mentoring, structured training, professional development, management  support and commitment, Key Performance Indicators, a communication platform and information sessions to assist in decision making for rotational areas and experience.

pdf.png 2004 - October - Simes - SPAD Mitigation - A Regulatory View

Tony Simes B.Eng (Elec), MIEAust, CPEng

Australian Transport Safety Bureau

The responsibility for rail safety regulation in Australia lies with each State or Territory. Each State or Territory, with the exception of the Australian Capital Territory where rail safety is administered by New South Wales, has enacted its own rail safety legislation. The framework is based on co-regulatory principles, whereby each rail organisation is predominately responsible for the management of its rail safety related operations, and the Rail Safety Regulator responsible for administering each organisations accreditation and verifying their obligations under the relevant rail safety legislation.

A "Signal Passed at Danger" (SPAD), describes an incident when a train passes a stop signal without the authority to do so.

SPADs present one of the highest safety risks facing the rail industry and are only one precursor to a potentially catastrophic rail incident. They occur where there is an interface between drivers employed by Rail Operators, and signalling infrastructure managed by Track Owners. It is therefore essential that all parties co-operate and apply an appropriate level of resource and commitment to reduce the likelihood of a SPAD incident.

This paper presents a Rail Safety Regulators view on SPADs and their mitigation. The paper will discuss topics such as the investigation of incidents, the potential cause, evaluation of risks, identifying control measures and the periodical review of the risk management process. Issues relating to recording, reporting and trending of SPAD incidents at organisational, State and national levels will also be discussed.

The aim of the paper is to stimulate thought and discussion in the attempt to identifying new and innovative methods for improving rail safety and addressing the important issue of SPAD mitigation.
