Performance Metrics

CoMET Benchmarking Results 2013

The Community of Metros (CoMET) programme collects data from large metro system operators around the world in order to compare performance and improve standards across the industry. The data covers a number of important areas including safety, financial performance, environment, staff and customer service. The latest benchmarking exercise reflects data collected for 1 January 2013 to 31 December 2013 from metro systems in 15 cities, including Beijing, Berlin, Guangzhou, Hong Kong, London, Mexico City, Madrid, Moscow, New York, Paris, Santiago, Singapore, Shanghai, São Paolo and Taipei.

Why Do We Participate in CoMET?


Our passenger safety record in 2013 reflects two fatalities, which are recorded within the KPI for deaths from accidents in the CoMET benchmarking results for that year. This KPI includes deaths due to an accident on metro property or trains operated, owned or maintained by the metro, or due to metro operations, if death occurs within 30 days of an event. During 2014, we have achieved significant improvements on KPIs for passenger and public safety, which should be reflected in the benchmarking results for 2014.

Financial Performance

In 2013, we continued to outperform all other CoMET participants on the indicator for total commercial revenue per operating cost, which reflects the success of our sustainable financial models. This year, we have started to report on a new indicator, fare revenue per passenger km, which shows that over the past five years we have generated average levels of revenue from passenger fares compared with other metro operators. At the same time, in 2013 we sustained an improving trend on two measures of normalised operating cost, i.e. operating cost per revenue car km and per passenger journey.


This year we have started to report on a new indicator, CO2 per passenger km. Since we exercise minimal influence over the source of electricity that we consume, our efforts to mitigate climate change focus on improving energy efficiency. The CoMET benchmarking results show that we are sustaining an improving trend for energy consumption per passenger km, and our performance is better than average when compared with other metro systems around the world.

Customer Service

Comparing punctuality and reliability of our train services with other metro systems, our passengers in Hong Kong enjoy good service by international standards but there is still room for moderate improvement. Despite the problems we are currently experiencing with crowding during peak hours, the data on capacity utilisation shows that we operate our services in an efficient way, doing our best to transport our passengers over the existing network.


Deaths from accidents per billion passenger journeys* — a measure of passenger safety.

*Please note that this KPI is slightly different from Fatalities per billion passenger journeys, which is the KPI that we reported in previous years.

CoMET and Nova are metro benchmarking groups currently comprising 32 large and medium sized metro systems from 30 cities. The groups are jointly owned and steered by their members, and are facilitated by the Railway and Transport Strategy Centre (RTSC) at Imperial College London.



Passenger journeys – The total number of passenger trips on our trains during the year

Passenger km – The total number of kilometres travelled by passengers on our trains during the year

Car km – The total number of kilometres which were operated by our trains in revenue (passenger carrying) service during the year
