      <title>Melbourne's Suburban Rail Loop (SRL) project: SRL East project update</title>
      <link>https://trid.trb.org/View/2563095</link>
      <description><![CDATA[Suburban Rail Loop (SRL) will deliver a 90km rail line linking every major train line in Melbourne, from the Frankston line to the Werribee line, via Melbourne Airport. SRL will transform Melbourne into a polycentric city, enhancing liveability by providing all Melbournians with equitable access to quality jobs and employment centres, greater and more affordable housing options, and green and open spaces in attractive, well-connected neighbourhoods. Furthermore, SRL will connect culturally and socially diverse communities, and link existing National Employment and Innovation Clusters, Metropolitan Activity Centres (MACs), and Health and Education Precincts (HEPs). SRL East from Cheltenham to Box Hill is in early stages of construction. SRL East Initial and EarlyWorks commenced in 2022 with completion expected by 2035. SRL East comprises 26km of twin-bored tunnels and six new underground stations at Cheltenham, Clayton, Monash, Glen Waverley, Burwood, Box Hill, and a train stabling and maintenance facility at Heatherton. The SRL East tunnels and station box excavations transition through a range of geological units ona regional commenced in 2022 with completion expected by 2035. SRL East comprises 26km of twin-bored tunnels and six new underground stations at Cheltenham, Clayton, Monash, Glen Waverley, Burwood, Box Hill, and a train stabling and maintenance facility at Heatherton. The SRL East tunnels and station box excavations transition through a range of geological units ona regional scale, including saturated Tertiary aged sands, granodiorite intrusions, high strength Silurian siltstone and anthropogenic filling. An extensive, phased investigation approach has been completed to progressively identify and mitigate geo-environmental delivery risks for tunnelling through planning and construction. In addition to tunnelling and station excavation, associated works include extensive ground improvements, cross passage excavation, infrastructure protection works and multiple TBM launches/retrievals. Mitigations through design and delivery will enable the project to effectively traverse highly urbanised environments, interfacing with multiple communities, existing infrastructure and receptors of varying sensitivity. A detailed Reference Design has been developed by Suburban Rail Loop Authority (SRLA). Tunnelling and station excavation works have been split over two packages, with the procurement process having commenced in 2022. This paper outlines the SRL East project and describes how the core objectives of the project tunnelling packages are being met through investigation, development, procurement and delivery strategies. The presentation describes the extensive investigation programme completed and exploresthe factors driving the tunnel alignment. The scope of key underground construction works is described, along with the technical measures adopted to manage construction delivery. Finally, the presentation overviews the tunnelling package and procurement approach, how it responds to the current construction market and outlines the collaborative contracting approach adopted in procurement.]]></description>

      <title>City Rail Link case history comparison of embedded carbon of four tunnels</title>
      <link>https://trid.trb.org/View/2563077</link>
      <description><![CDATA[The City Rail Link (CRL) in Auckland, New Zealand is the largest transport infrastructure project ever to be undertaken in New Zealand at a cost of NZ$5.493B. CRL includes a 3.45 km twin-tunnel underground rail tunnel underneath Auckland's city centre, between Waitemata Station (Britomart) and Maungawhau Station to double Auckland’s rail network capacity. An earth pressure balance tunnel boring machine (TBM) was used to construct 3.2 km of the tunnels between Maungawhau and Te Waihorotiu. Tunnels in the Mt Eden area were also constructed using mined (SEM) techniques and both bottom-up and top-down cut-and-cover tunnels. This paper explores the resulting embodied carbon of the different tunnelling methods. CRL will be a low carbon travel option for Aucklanders, but it requires significant carbon cost to construct. A key factor in decisions made in the early design phases of the project was to consider the energy and materials-related footprint of temporary and permanent works in constructing the tunnels. High quality data from design and construction allowed the footprint to be calculated. Four different methods were used for two tunnels with a similar cross-sectional area within a small geographical area. This allows a direct comparison which will be of benefit to future decision-makers.]]></description>

      <title>Real-time railway perception and change detection</title>
      <link>https://trid.trb.org/View/2550868</link>
      <description><![CDATA[Track work inside the rail corridor is inherently high risk. Current practice often requires personnel to enter the danger zone to install safety and isolation equipment before works commence. This, coupled with the projected long-term increase in network utilisation, creates a scenario of foreseeable increased worker risk that should be addressed. This project, which was jointly funded by ACRI/NTRO and iMOVE and undertaken by the University of Newcastle, sought to develop enabling smart technologies that minimise human exposure to risk within the rail environment. It involved development of a general purpose sensing platform that can accurately determine its position within the rail corridor, detect changes and track dynamic objects, including people, as they operate within the space. The challenge was to develop a sensor that had the following capabilities: 1. Construct maps and localise within the rail corridor; 2. Detect and track objects of interest, such as personnel, within the corridor. Furthermore, it needed to be a lightweight, standalone solution that performed these functions in real time, with the capacity to be applied to a variety of platforms for fixed location and dynamic application. This paper presents the efforts on developing a solution to this problem. In the first project a prototype of the robotic trackside device was constructed. This served as the platform for the development of the real-time perception sensing capabilities undertaken in the second project.]]></description>

      <title>Evaluation of the Northern Sydney Freight Corridor: final report</title>
      <link>https://trid.trb.org/View/2521611</link>
      <description><![CDATA[Between 2012 and 2016, Transport for NSW (TfNSW) undertook upgrades of the northern Sydney rail freight corridor (NSFC) with the intention to improve freight and passenger rail operations along the corridor and address future capacity needs. The NSFC program of works was stage one of a broader vision to increase freight rail services through the metropolitan network. The program consisted of 4 separate infrastructure upgrades between Strathfield in the Sydney metropolitan area, and Broadmeadow near Newcastle. It included an underpass, additional tracks and passing loops. The NSFC primary objectives were to increase the number of freight paths during off-peak times, improve reliability, time in the network, and service offering to facilitate an increase in freight on rail. In addition, it was expected that these works would accommodate the expected increase in passenger services in line with population growth. This study examines the NSFC program of works, its place in the wider north coast rail corridor and ability to meet the stated program objectives in the original NSFC business case. The NSFC is considered in the broader context of the shared rail network including impacts from the introduction of the 2017 timetable. Key metrics used to understand the service reliability and service provision include on-time running, number of freight trains in the network and maintenance schedules. Consultation with stakeholders provided additional qualitative information rounding out the overall assessment of the NSFC. In addition to the primary objectives, this report examines the program’s ability to deliver other benefits including safety, sustainability and reduction in emissions and noise.]]></description>

      <title>Exploring crashes involving light rail vehicles in Canberra</title>
      <link>https://trid.trb.org/View/2509228</link>
      <description><![CDATA[Light Rail Vehicle (LRV) services commenced operation in Canberra in 2019. Since then, crashes have occurred involving LRVs and other road users, specifically motor vehicles, pedestrians and cyclists. ‘Target 2030’ aims to reduce the number of crash-related deaths and serious injuries by 50%, with the Safe System approach key to achieving this target. The Safe System approach highlights that humans make mistakes, but these mistakes should not lead to serious injuries or deaths. Recognising this, the current research examined the circumstances surrounding 18 crashes involving LRVs in Canberra, identifying a series of potential countermeasures that could be considered to prevent similar incidents in the future. These potential countermeasures included: changes to traffic light design and timing, speed of LRVs and preventing pedestrians crossing at undesignated locations. The results have value in providing important information to be considered when developing Light Rail systems, and importantly a pathway toward achieving ‘Target 2030’.]]></description>

      <title>Atmospheric pollution reduction by shifting freight/container movement from road to rail</title>
      <link>https://trid.trb.org/View/2475156</link>
      <description><![CDATA[The Transport sector accounts for about 18 percent of Australia's emissions in 2020. While the COVID-19 economic recession reduced transport activity largely, these emissions are projected to be 100 Mt CO2-e in 2030. Particularly, the emissions from road vehicles supporting freight are expected to be one of the biggest emission categories to accommodate the growing imports/exports demand. The urban heavy-duty trucks (in tonne-kilometres) dedicatedfor freight have tripled in the past three decades while the interurban articulated-truck freight have quadrupled over the same period. In fact, apart from being a significant source of air pollution, transport is the main contributor for some hazardous pollutants compromising the health of our environment. As it turns out, the rising metropolitan congestion costs are also adding complexities and unnecessary expenses to the optimal performance of commercial businesses. Efforts to reduce the energy use in freight transportation generally centre on 'mode-based' approaches, including the shift of freight movement from energy-intensive modes to energy-efficient modes, for example, trucks to the rail. In this paper, the authors will discuss on an innovative practical approach to reduce the atmospheric pollution in industrialised cities through the concept of Ship-to-Rail direct loading of freight and effectively contribute to the nations ' 2030 overall carbon emissions target.]]></description>

      <title>National standard for health assessment of rail safety workers</title>
      <link>https://trid.trb.org/View/2452454</link>
      <description><![CDATA[Under the Rail Safety National Law (RSNL), rail transport operators are required to manage the risks posed by the ill-health of rail safety workers. The National Standard for Health Assessment of Rail Safety Workers provides practical guidance for rail transport operators to meet these obligations. This responsibility is an essential part of a rail transport operator’s rail safety management system1 which aims to minimise risks and protect the safety of: a. the public; b. rail safety workers and their fellow workers; c. the environment. The Standard applies to all rail transport operators and to all rail safety workers nationally. The Standard recognises health assessments as one aspect of an integrated management system aimed at achieving a high level of safety throughout the rail network.]]></description>

      <title>Health cost of land transport noise exposure in New Zealand</title>
      <link>https://trid.trb.org/View/2452438</link>
      <description><![CDATA[We know from existing research that road and rail noise is linked to negative effects on our health. Between 2020 and 2022, researchers of this study investigated this link to estimate just how much it costs the New Zealand economy. After uncovering credible evidence, researchers studied the cost of three health effects associated with exposure to road and rail noise: annoyance, sleep disturbance, and ischaemic heart disease. Researchers estimate that about $654 million is spent each year on these health effects resulting from road and rail noise. Road noise contributes to most of this cost at about $502 million a year. This complex study required researchers to model the noise from New Zealand’s road and rail networks, and work out the size of the population affected by this noise. They then developed a model to estimate the health cost of transport noise related to each of the three health effects. Researchers tested the cost model to determine the potential range of the estimated costs. Findings from this study make it easy to identify which parts of New Zealand are most affected by road and rail noise. The findings will also help stakeholders understand how people might be affected by a projected increase or decrease in exposure to transport noise.]]></description>
