2022 – November – Fraser – Train Positioning in Tunnels using Ultra-Wideband
By: Aaron Fraser
Date Presented: November 2nd, 2022
Aaron FraserUltra-Wideband (UWB) technology is a radio frequency technology that uses a very large bandwidth to transmit and receive small pulses that are used to calculate precise locations. UWB has been proven to provide industry-leading positioning wit

2022 – November – Bonassa et al – Tunnel Solutions for Modern Transportation Systems – A Holistic Approach
By: Stefano Bonassa, Giacomo Cernelli, Massimo Orsi, Federico Nardi & Anthony MacDonald
Date Presented: October 21st, 2024
Stefano Bonassa, Giacomo Cernelli, Massimo Orsi, Federico Nardi & Anthony MacDonald Typically, the integration of the Signalling System, Platform Screen Door PSD, Tunnel Ventilation System TVS, Automatic Train Operation ATO, SCADA and other particular equipment, which interact with Signalling in and around the Tunnel, create new requirements to be allocated to innovative signalling systems like ETCS or CBTC.

2022 – November – Boldeman – Systems Engineering – Myths and Realities
By: Steven Boldeman
Date Presented: October 21st, 2024
Steven Boldeman Within the last decade, Systems Engineering has been used with more and more industries, and has been adopted within the rail industry. This paper discusses the reality of practice for systems engineering in Australia, and in particular for the rail industry. Systems engineering is a relatively new field in Australia for rail and the application of the field to the rail industry is developing and improving as time progresses. There have been hard lessons.

2022 – April – Wagner – Implementing an integrated system delivery framework to enable successful delivery of complex, multidisciplinary projects
By: Thomas Wagner
Date Presented: October 21st, 2024
Thomas Wagner The aim of this paper is to propose the use of an Integrated System Delivery framework approach for the implementation of complex, multidisciplinary projects. The paper summarises the current spending in the Australian rail market and the industry trends and practices related to the delivery of megaprojects. It looks at traditional design and construction delivery approaches for such projects and investigates their appropriateness compared to the proposed integrated approach. Key changes in approach such as the impacts Covid has had on project teams, common factors that contribute to project failures and the existing use of systems and digital engineering are discussed. The paper provides an overview of the proposed Integrated System Delivery framework for projects and outlines key aspects of the framework that support a new approach to design, construction and implementation phases of complex, multidisciplinary projects.

2022 – April – Rahman – Reconnecting with Concepts of Collection, Verification & Maintenance of Accurate Geographic Data for ATP
By: Subrina Rahman
Date Presented: October 21st, 2024
Subrina Rahman When presented with a set of flawed input data, the best-case scenario a system designer can hope for is that the system will recognize the flaw and stop working; and in worst case it will keep working with the erroneous data and produce an unpredicted outcome. This is true for simple systems being designed by university students to safety critical complex systems like the Automatic Train Protection (ATP) system currently being rolled across the greater Sydney’s heavy rail network. Only in the latter case, flawed input data could cost lives.

2022 – April – Moore – Level Crossings – Controlling the Hazards
By: Trevor Moore
Date Presented: October 21st, 2024
Trevor Moore Level crossings encompass many hazards including the uncontrolled hazards associated with motor vehicles and pedestrians. This paper examines a variety of hazards impacting on level crossing safety. There are also references to incident reports which are a good source for hazards and their consequences.

2022 – April – McGregor – Motor generators, 240V (MEN) and Isolated power supplies for signalling
By: Peter McGregor
Date Presented: October 21st, 2024
Peter McGregor In NSW country areas we have historically used diesel motor generator sets to provide 120V AC power to operate signalling equipment in the field. With new technologies with electronics/inverters and the drive to use COTS (Commercial off the shelf) equipment we are using 240V commercial generator sets as opposed to the customised (e.g., Lister brand) old style generator sets at 120V AC.

2022 – April – McGrath – The “Obsolescence Problem” in Signalling
By: Alex McGrath
Date Presented: October 21st, 2024
Alex McGrath The ‘obsolescence problem’ in signalling is a topic of much discussion and consternation. This paper focuses on the different types of obsolescence and the system elements and forces which drive the ‘problem’, to get a deep understanding of the landscape.

2022 – April – Lemon – Can ETCS Level 2 help us reconnect the Australian rail networks and offer an interoperable and harmonised future for our railways?
By: Stephen Lemon
Date Presented: October 21st, 2024
Stephen Lemon As a result of Australia’s colonial history the state railway networks have evolved very differently, and whilst differences in track gauge have been largely resolved, there remain major differences between the signalling and train control systems that continue to present significant challenges for interstate and inter-network train operations.

2022 – April – Cox – Trainguard MT Communications Based Train Control
By: Simeon Cox
Date Presented: October 21st, 2024
Simeon Cox The backbone of large cities is their mass transit, supporting the needs of the population and providing a dependable pathway between nerve sites. Over the next 30 years, several Australian capital cities will be approaching ‘Mega City’ levels of population and will need to consider high-capacity metro systems to move their population as they ‘re-open’ following the COVID 19 pandemic. Access to efficient public transport provides greater equity in access to employment and educational opportunities across the population of the city as people return to the office, workplace, and classroom. Since 2006, Siemens Trainguard MT CBTC has been at the centre of high-capacity metro railways operating at GoA2 and GoA4 in cities worldwide.
