Research: Energy Efficiency

The COVID-19 pandemic and the resultant economic downturns have had a steep impact on global energy production and supply chains. Inevitably COMET members, who are often one of the largest consumers of energy in their cities, were deeply affected by the energy crisis.

The study collected information from 32 metros, reviewing where metros procured their energy from and their trends in consumption, as well as benchmarking metros’ performance regarding energy efficiency and energy costs. The key objective of the study is to understand the impacts of energy crisis on metro operations, and the energy saving measures that have been successfully undertaken by members – which covers multiple areas such as lighting, HVAC, regenerative braking, escalators, driving modes and stabling, etc. An overview of pilot initiatives and technologies that are considered by metros in the future was also included in the report to explore further in future.

Community of Metros News: COMET 2023 Annual Meeting in Dubai, 12-16 November

The Transport Strategy Centre (TSC) together with Roads and Transport Authority (RTA) of Dubai welcomed over 70 attendees from 28 member metros during the COMET 2023 Annual Meeting in Dubai. This was the first major opportunity for all COMET members to come together in person since the COVID-19 pandemic.

The meeting started with an executive day based on the themes of financial, operational, and environmental sustainability. Metro executives discussed shared challenges in the new post-COVID period, and heard wide-ranging discussions on the potential future opportunities from other metros.

The remainder of the meeting consisted of breakout sessions on the topics of technology and innovation, KPI presentations across several success dimensions, and structured discussions on the topics of staffing and reliability. Members also heard the latest update on Transport for London’s Elizabeth Line 18 months after its opening, and from new member Bangalore BMRC on their challenges and lesson learnt from its rapid network expansions.

During technical visits, delegates visited the multi-agency Enterprise Command and Control Centre, Expo Station, and RTA’s Operational Control Centre where members had discussions with Dubai metro operator, Keolis-MHI, and learnt the details about the operations and maintenance contract. Thank you to RTA for its generous hosting of a very interesting and successful COMET Annual Meeting.

Research: Operational Impacts of New Fleets

Introducing new fleets is a major, transformative project for metro operators, so managing these projects and mitigating their impact on existing operations has been of interest to COMET members. The study proposer, Newcastle Nexus, has been replacing its entire fleet in recent years and thus is keen to discover metros’ experiences in this area to deploy best practices and minimise impacts.

Based on responses from 32 metros, the study explored key tasks, typical time periods, common issues, and implemented solutions during different stages of fleet introduction phase, starting from pre-commissioning stage to final acceptance. Examples of best practices for each stage were presented, along with a summary of metros’ recommendations for future fleet introductions with a focus on project planning, risk management, and quality control.

Research: Recruitment and Retention

The entire recruiting environment has changed greatly since the COVID-19 outbreak therefore many metros have experienced new issues in recruitment and retention. In addition to the pandemic impacts, other factors, such as rising cost of living, expectations of younger generation, and aging workforce, make recruitment and retention more challenging than ever before. The study looked at the extent of recruitment and retention issues that are experienced by metros, identifying reginal difference, key drivers, and most affected roles. It also reviewed staff turnover rate and average time to fill in vacancies in recent years, and the COVID impact on both indicators.

Regional difference in recruitment issues faced by metros

The report outlined implemented improvements and initiatives, with a summary of the emerging trends in improving recruitment and retention performance. Metros’ long-term plans for recruitment and retention and their advice based on their own experience are also covered in the report.

Research: Drivers of Metro Ridership

Ridership has taken on dramatically more importance at metros since the early pandemic, when public transport demand collapsed in an unparalleled way. Metro operators have observed notable changes to travel patterns since the COVID-19 outbreak and therefore have been closely monitoring ridership trends, adding ridership-related KPIs to strategic scorecards, and proactively marketing and promoting their services in new ways.

The study summarises the main enablers and barriers of ridership, metro expectations for long-term demand forecasts, and metro initiatives to drive ridership growth. The initiatives taken by metros before and during the pandemic to promote ridership growth were explored in the six key categories as shown below.

Community of Metros News: Virtual Events from January to July 2023

In addition to the resumption of in-person meetings, COMET continued to run the full virtual events programme in 2023. The virtual events held from January to July include:

  • Case Study Webinar on Drivers of Metro Ridership, Data Governance, and Energy Efficiency. Members heard presentations from TSC on the key findings of the studies, and from metro highlight presentations delivered by specific metros who have advanced development in the areas.
  • General Meeting occurred in February and July for members to share the latest development and challenges. TSC presented the latest findings from case studies and data benchmarking, as well as the recent activities and work programme of COMET.

Research: Data Governance

Transforming the large volumes of raw data that metro operators collect into actionable intelligence is a challenging task, yet critical to enhance operations, improve customer service, and develop effective future strategies. To overcome these challenges, good data governance is needed to support data management, enable informed decision-making, and ultimately improve overall performance.

Data governance mainly focuses on data-driven decision making and provides a framework for managing data throughout its lifecycle, ensuring its quality, security, privacy, and effective utilisation. It aims to assist organisations in deriving maximum value from their data assets while minimising risks and complying with legal and regulatory requirements.

The study details three main aspects of data governance (organisation, technical, and business) and presents a data governance roadmap along with metros’ best practices.

Community of Metros News: CBTC Workshop in New York, 10-13 July

An expert workshop on Communication-Based Train Control (CBTC) took place in July, hosted by New York NYCT. The workshop was hosted jointly with the International Suburban Rail Benchmarking Group (ISBeRG) of TSC. Over the course of three days, forty attendees joined from sixteen metros and one railway who were planning, installing, or had already implemented CBTC.

TSC and members presented on three key themes: challenges when migrating to CBTC, how to prepare for implementation of CBTC, and how to best leverage CBTC to benefit metro operations. The delegates had in-depth discussions around these topics and exchanged ideas based on their own experience.

Members also took part in technical visits to the NYCT Rail Control Center as well as the Corona Maintenance Yard to view signalling infrastructure. Additionally, New York PATH welcomed delegates to their operational control center based in New Jersey. Very positive feedback was received after the event and members are looking forward to the next in-person CBTC workshop.

Research: Combatting Crime and Disorder on Metro Networks

Managing security – and perception of security – is a growing challenge for many metro operators. In North America and Europe where crime and disorder is a significant concern for metros, perception of security in public spaces has been influenced by wider quality-of-life issues that pre-dated COVID-19 related to homelessness, drug and alcohol use and mental health. The pandemic also raised new challenges of staff unavailability and lower ridership which reduced the presence of ‘active bystanders’ on metro networks.

Factors influencing crime in metros

As such, the study aims to understand changes in crime and anti-social behaviour since the pandemic began, and to share initiatives implemented by metros to reduce incident rates and to improve customer perceptions of personal safety. This report contains data compiled from twenty-seven COMET members, including an in-depth interview with the Deputy Chief of Police at San Francisco BART. It reviews factors impacting crime in metros, key barriers to improving security, incident rates during pandemic, as well as opportunities and actions to combat crime and disorder.

Community of Metros News: COMET 2023 Eastern Meeting in Kuala Lumpur, 23-26 May

After the successful in-person 2023 Western Meeting in San Francisco, the Transport Strategy Centre (TSC) had the pleasure of welcoming COMET members during the 2023 Eastern Meeting, which was hosted by Kuala Lumpur Rapid Rail. Despite being a smaller group with seven metros, the intimate setting allowed for in-depth discussion on various topics, including financial performance and future funding, station staffing and recruitment, metro demand, energy efficiency, and reliability performance.

During the technical visits, members visited the Sungai Buloh Depot and the Operational Control Center, as well as experienced a ride on the new Putrajaya Line. The line was officially launched in 2021 with an extension through the city centre reaching south near the airport in March 2023.
