Notice: Warning re contractual on-time running metrics

[ozbob]

Last week it was discovered that Queensland rail is not including delays due to mechanical issues ( rollingstock faults ) with the New Generation Rolling stock trains.

Queensland Rail updated their website at https://www.queenslandrail.com.au/aboutus/ourperformance/service-punctuality-and-reliability when this was discovered by a Couriermail journalist, as follows:

" The on-time running of Citytrain services is a priority for Queensland Rail. We make every effort to ensure our services adhere to the published timetable.

Our on-time running performance targets are the most stringent in Australia. We aim to have more than 95% of our peak period services arrive on-time. All services, including peak and off-peak, are measured on time when they arrive within three minutes and 59 seconds of their scheduled time (5 minutes and 59 seconds on interurban services; ie Gold Coast, Rosewood and Nambour).

Sometimes incidents beyond Queensland Rail's control may delay our services (force majeure). Such incidents may include severe weather activity, onboard medical emergencies, security incidents, vehicles striking level crossing boom gates, and third party rollingstock faults including the New Generation Rollingstock fleet which is not owned or maintained by Queensland Rail. Because these incidents are out of Queensland Rail's control, they are not included in the contractual results. However Queensland Rail recognises delays, regardless of their cause, affect customers, and this is reflected in the customer impact figures. "

So since the introduction of New Generation Rollingstock trains in December 2017, the contractual measurement has become increasingly less representative of the overall network performance. When all 75 NGR trains are in service, they will represent around 56% of the operating train fleet, so the contractual on-time running measurements are now largely meaningless.

​The data presented below is for the morning and afternoon peak periods over the past five days.

The information provided is correct at the time of posting. However, as further information about the causes of any delay are collated the data may change, particularly to reflect differences between force majeure and non force majeure incidents. Please note that as of 1 January 2019 NGR related delays are not considered force majeure in the calculation of the contractual figures below.

This is what should have been done from 11th Dec 2017!
