Rail performance results

Auckland Transport and Transdev keep track of the performance of the rail network and report on a monthly basis - with more than 17 million passenger trips per year taken on the network, we endeavour to make the rail network as punctual as possible. We measure the overall performance of the rail network according to how many scheduled train services reach their destinations and run on time.

Transdev operates rail services on the Auckland Passenger Rail Network for Auckland Transport (AT). Transdev takes its commitment to customers seriously and is working hard to support AT in the upgrading of rail infrastructure and improvement of train reliability.

Since March 2009, Transdev has provided performance results on a line by line basis each month.

Train performance is measured as follows:

  • Punctuality measures the percentage of services arriving at their final destination within 4 minutes and 59 seconds of their scheduled arrival. This is usually referred to as "on time to 5 minutes" and is an international timekeeping standard.
  • Service Delivery measures the percentage of scheduled services that arrive at their final destination.
  • A 12-month rolling average for punctuality, service delivery and an analysis of significant events affecting performance will also be provided each month.
