Research: Reliability of Signalling Equipment

Signalling is a safety- and service-critical metro asset. Across CoMET and Nova metros, signalling is the second-highest cause of delay incidents, and cause approximately half of all delay incidents for very reliable metros. This study analysed information from 26 metros about their signalling equipment, looking in detail at six sub-assets: point machines, interlockings, track circuits, axle counters, train stops, and signal heads. The study compares these sub-assets, including their age, reliability, and inspection/maintenance regimes, and collects initiatives that metros are pursuing to improve signalling reliability.

Metros with older and more traditional signalling systems tend to have more trackside signalling equipment, which may lead to more potential for failure and greater need for maintenance interventions to maintain reliability. To improve signalling reliability metros are rationalising their asset bases, as well as pursuing both solutions that can be retrofitted into their existing systems and new systems such as CBTC.

Research: Digital Transformation of Metros

The Digital Transformation of Metros study reviewed the strategies, initiatives, and technologies used by metros to implement digital transformation for four key purposes: safety improvement, station operations and management, train operations, and depot management. In recent years there have been several digital trends observed in metros, including provision of real-time train loading information, centralised station management, customer-facing staff equipped with tablets, installation of passenger counting equipment, etc. Metros’ long-term digital transformation plans typically involve multi-phase programmes with strong support from management, employee expertise, and partnership with external parties. Ultimately, digital transformation is highly related to transforming employees. Therefore the study summarised metros’ good practices to create a digital culture, as well as ways to remove barriers along the journey to digital transformation.

Community of Metros News: Tokyo Metro Joins CoMET

Tokyo Metro has joined the CoMET group of metros. Their system is the oldest in Asia, dating to 1927 with the opening of the Ginza Line. Privatised in 2004, Tokyo Metro is owned by the national and metropolitan governments. The Tokyo Metro network is 195.1km with 179 stations on 9 lines and is renowned for its punctuality. Annual passenger journeys are estimated at more than 2.2 billion, making Tokyo Metro among the densest metros in the world.

Tokyo Metro’s first two lines, the 1927 Ginza Line and 1954 Marunouchi Line, operate on standard gauge track with third rail power and are independent. The rest of the network operates on narrow gauge (1067mm) like the mainline railway network in Japan, with overhead power and operate through services connecting to various suburban railways. We look forward to working with Tokyo Metro on benchmarking going forward.

Community of Metros News: Sydney Metro Joins Nova

Sydney Metro has joined the Nova group of metros. It is a new fully automated (GoA4) metro system being built in Sydney, Australia’s largest city. The first section, known as Sydney Metro Northwest, opened in May 2019 with a 4-minute peak headway. The initial segment features 23km and 8 stations newly built and the existing 13km, 5-station Epping to Chatswood rail link (which opened in 2009 and was operated by Sydney Trains until closing in September 2018 for metro conversion).

 “The Operator’s Story” at the OECD International Transport Forum, Leipzig

Richard Anderson, Professor Dan Graham, Dr. Roger Allport and Priya Wells attended the 2017 OECD International Transport Forum to bring the ongoing “Operator’s Story” research project to industry experts and policymakers from around the world. The RTSC team were joined by Dominic Patella, Senior Transportation Specialist at the World Bank, and an expert panel made up of Dr Jacob Kam of Hong Kong Mass Transit Railway, Ismael Uruen Pueyo of Transports Metropolitans de Barcelona and Professor Tony Ridley of Imperial College London.

“The Operator’s Story” is an applied research project aiming to capture and document what makes metros successful from the Operator’s point of view, a perspective that has been little explored. 10 members of the Community of Metros participated in in-depth case studies for the research, providing insight into their governance structures, operational opportunities and constraints, and relationships with stakeholders. These findings have been combined with long-term metro benchmarking to present a set of initiatives that actively improve metro success, for application to existing and new metro systems alike.

Examples of external factors affecting metro operators

Richard Anderson, Roger Allport and Dominic Patella presented the emerging findings of the research, focusing on the increasing trend towards urbanisation and the use of metro rail as a solution to promote sustainable growth. Roger Allport presented key insights from the in-depth case studies, focusing on strategic and governance practices. Using best practice insight from the Community of Metros, Richard Anderson presented some of the key operational principles of metro development.

RTSC presents big data research to President Xi Jinping

Chinese President Xi Jinping visited Imperial College London on the 21st October. As a result of a collaboration between the RTSC, Shanghai Metro, and the Data Science Institute (DSI) of Imperial, the Presidential visit included a presentation on the analysis of smartcard data for the Shanghai Metro network.

PresidentialVisit02

Our main research objective was to improve our understanding of demand patterns captured in smartcard data. We visualised passenger flows entering and exiting Shanghai metro stations using the extraordinary visualisation capabilities of the KPMG Data Observatory of DSI. The Data Observatory is the largest of its kind in Europe, featuring an enveloping circular wall of 64 monitors powered by 32 computers facilitating 313 degrees of surround vision.

In the second part of the presentation we visualised a simulation scenario for a hypothetical train service disruption. This allowed us to predict how temporary demand shocks would spread through other parts of the network. Studying disruption scenarios enables operators to prepare for unexpected events and improve the resilience of urban rail networks.

The Presidential visit proved to be an excellent opportunity to showcase the RTSC’s recently developed competences in big data analysis, and the potential of smart card data in cutting edge public transport research.
