\r\nServices began at 05.48 this morning, and despite some minor technical problems, which caused some delays, commuters praised the new services which are reducing journey times and increasing capacity. The introduction of electric services followed an open day on Sunday for 5000 ticket holders who were able to take a 20 minute return journey from Britomart to Newmarket.\r\nThe introduction of the trains marks the completion of the Auckland Electrification Project, which had a budget of $NZ 500m ($US 429.3m) and involved installing 3500 overhead masts to support the 25kV ac electrification system. Siemens supplied and installed a new train control system for the project, which includes bi-directional signalling and an updated centralised control system.\r\nCAF secured a $NZ 420m contract for 57 trains in 2011, which are based on the trains supplied to London's Heathrow Express. Each 72m-long vehicle has capacity for 357 passengers, including 230 seated, which is 40% more than the former Perth and Western Australia DMUs which they are replacing, and can operate at a maximum speed of 110km\/h. CAF New Zealand will maintain the new EMUs at a new depot in Wiri, South Auckland, until 2026\r\nThe remaining vehicles will be introduced on the Eastern Line between Britomart and Manukau via Glen Innes and Panmure in late 2014, the Southern Line from Britomart to Papakura via Newmarket in early to mid 2015, and on the Western Line from Britomart to Swanson and Henderson in mid to late 2015.\r\nThe introduction of the new electric services has increased calls from the city of Auckland and opposition parties to build the City Rail Link, which involves constructing a new 3.5km twin-bore tunnel between Eden Terrace and Britomart, and will allow more train to pass through the station avoiding a reversal.\r\nAuckland mayor Mr Len Brown says that without an accelerated start of the project, Britomart will soon be bursting at the seams.\r\nHowever, the government has been reluctant to invest in the $NZ 2.9bn project. It says it is willing to meet 50% of the cost, but only if patronage is on course to reach a target of 20 million trips before 2020 and that central business district jobs are growing by 25%. Brown believes that with the introduction of electric services that Auckland will meet this target "pretty quickly" and has called for the start of construction in 2016.\r\nFor an in-depth look at Auckland's commuter network development plans see the December 2013 issue of IRJ, p32, or click here.
