2013 – July – Strike and Crivelli – Using Axle Counters for Block Control The ARTC Experience

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

Michael Strike Managing Director Selectrail (Australia) Pty Ltd Jarrod Crivelli Project Engineer Selectrail (Australia) Pty Ltd Utilisation of axle counters over the last two decades has been expanding to encompass many signalling and non-signalling applications. Their uses range from simple triggering devices for wayside equipment such as hot box detectors and weighing systems, to more complex train detection systems for train signalling. The use of high quality fail safe (SIL4) axle counters for occupancy detection have been widely applied in Australia for short track sections where communications are reliable and visual cues provide an extra level of safety confidence. Life cycle costs can be substantially lower with axle counters when compared to other technologies and with advancements in technology; capital costs can also be reduced. Longer block sections introduce an extra degree of design and procedural complexity. In the past, it has been difficult to appreciate the benefits of axle counters in these longer sections. The experience of the Australian Rail Track Corporation with small scale applications has allowed development of good operating procedures and the confidence to expand their use to block sections on the Spencer Junction to Tarcoola Line in South Australia.

2008 – July – Huth – Overview of QR Signalling Principles

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

Paul Huth BE(Elec), RPEQ, AMIRSE QR Network This paper provides an overview of the signalling systems and principles that are used on the QR network (excluding the standard gauge between Acacia Ridge and the NSW border). The content is intended to be informative only, describing the nature and meaning of aspects displayed to drivers, typical interlocking functions provided by control systems, and an overview of some of the technology systems that are used as part of the overall signalling system. Note that this paper is not intended to be comprehensive, or to be used as a design specification or design input. In some cases, a simplified description of the principle is provided to convey the intent, rather then providing a full description of the requirement. More detailed signalling specifications are available to designers of systems for the QR network. A number of these are listed as references to this paper.

1990 – Apr – Aitken – Does Centralised Control Mean Centralised Communications or Did Murphy Err?

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

John Aitken BE, MIEEE, AMIRSE Director Aitken & Partners Consulting Engineers The Sydney North Shore Times recently related a tale which should bring a chill to the spine of communications and signals engineers. I quote: Police say the series of events began at 3.00 pm on April 9 when the man visited a patient at Royal North Shore Hospital, St Leonards. As he was leaving, he saw a Chubb safe in one of the hospital offices. He placed the safe and a key locker on a hospital trolley and towed them to his car. He tied a rope around the safe and the trolley and tied them to the car bumper. He then towed the trolley along the Pacific Highway until the wheels fell off the trolley. The man got out of the car, unhooked the trolley and tied the rope to the safe, dragging it another 400 metres as sparks flew off the roadway. When he reached his home unit, he hired an angle grinder and cut the backing plate off the safe. Lane Cove police went to the home unit after the man's neighbours had complained about the noise. They found the man in a distraught state who told them he had found only $20 in the safe after he had finally opened it. Police said it cost the man $50 to hire the angle grinder. Communications and signals engineers are known and respected for their thoroughness and careful planning. They do not act on impulse but plan and design systems which are robust and have "fail-safe" operation and redundancy built in. None the less, the unforseen does occur. It may pass un-noticed, it may be identified as an incident or it may become a disaster. The impact is nearly always determined by the timing. If confirmation of this is needed one need only refer to Mr Nock's book "Historic Railway Disasters" or any issue of the "Aviation Safety Digest".

2007 – Oct – Murphy – The Application of ERTMS/ETCS System

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

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• Train operations• Signalling principles• Drivers and human factors• Rolling stock• Maintenance• Capacity• Migration 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.

2008 – March – Howker & Burton The Application of European ATP to Existing Signalling

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

Anthony C. Howker (Past President) Noel J. Burton (WRSA) HonFIRSE & AMIRSE The first part of the paper describes the basic principles of European Automatic Train Protection (ATP) and the how it may be applied to an Australian working railway. It covers the major principles of application, to both trackside and onboard. The paper also describes the controls needed in the signalling and the necessary requirements for both loco and multiple units. The second part of the paper describes in detail how the European Train Control System (ETCS) Level 1 technology was applied on a working railway in Australia. It describes the difficulties encountered and the solutions found in the signalling application. It also comments on the need for flexibility in signalling principles and how they can be amended or simplified with the addition of ATP.

2010 – Oct – Lawrie – Next Generation Signalling Capacity

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

Michael Lawrie MIRSE, GradDip Signalling, Bach Elec/Elect, Bach Bus Department of Transport Victoria Next Generation Signalling is a generic term that is being used in Victoria to describe a new signalling system. It is used is to enable deliberation about the concepts and principles, not about the technology or the supplier systems. It has been adopted to remove any ambiguity that arises when industry specific terms are used. Capacity is a key driver for a deployment of a Next Generation Signalling system. The existing signalling system imposes constraints on the capacity that can be delivered by the infrastructure. The Next Generation Signalling system seeks to address these constraints and enable a higher capacity railway whilst maintaining the high level of safety that the railway enjoys. This paper describes the constraints the existing signalling system imposes on the capacity of the railway and explores how the Next Generation Signalling principles can address these constraints and enable operations at a higher capacity than that traditionally available. Whilst the existing signalling system has served the railway well for almost a hundred years, Next Generation Signalling will offer Victoria significant benefits to capacity and bring Victorian signalling into the modern world.

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

Jan Stelmach MSc Elect Eng CPEng MIEAust D’ACE Design And Consulting Engineers The electrification of the Auckland passenger service is one of the biggest transport infrastructure projects undertaken by the government of New Zealand. The Auckland Electrified Area (AEA) consists of approximately 175 Single Track Kilometres over five existing, yet to be built and upgraded railway lines. This paper describes the general requirement for the railway fixed electrical infrastructure and then discusses the applied process and tools used to determine the most appropriate traction system for the Auckland electrification. It also points to the challenges encountered and solutions found during that process. The project is in progress and therefore this paper refers to its present status as at the end of September 2008.

2006 – July – Chadwick – TPWS – A Train Protection System for Regional Victoria

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

Marcus Chadwick BE (Elec), Dip Bus Mgt, MIRSE, MAIPM Asia Pacific Rail Until now, the maximum permitted train speed in Victoria has been 130 km/h. With the advent of the Regional Fast Rail project, train speeds up to 160 km/h will occur and in order to support this increase in operating speeds, a train protection system has been applied. TPWS was specified as the technology for the enforcement function of the Train Protection system after consideration of performance, cost and supply factors. This paper describes the development journey of the train protection system. From the selection and adaptation of the generic TPWS product through to its integration with the signalling system to form an effective train protection system. The paper identifies the objectives of the train protection function, highlights the differences between the UK application of TPWS and the Victorian application, details the engineering and signalling principles, and identifies the stakeholder consultation process adopted in delivering the train protection system.
