AT Metro general manager Mark Lambert notes that rail services have more than trebled since then, from 40,000 to 140,000 a year, and are now providing more than 13 million annual passenger trips.
Transdev's contract was quietly extended without an open tender in 2012 despite criticism of its performance at the start of the Rugby World Cup the previous September, when trains ground to a halt after being unable to keep up with the demand, making almost 1000 people late for the opening ceremony.
Auckland Transport indicated then that it wanted to retain the same operator for continuity reasons while rolling out its new electric trains.
Services have been under renewed pressure in recent weeks, exacerbated by trains breaking down and staff shortages created by training demands for the new electric fleet, but Auckland Transport expects improvements once it retires most of its diesel fleet by the end of July.
