The New Zealand AM class of electric multiple unit (EMU) was constructed for the electrification of Auckland's railway network. The class was introduced in 2014[7] with the first unit having arrived in September 2013.[8] The units are classified AM (Auckland Metro), with the driving motor car with pantograph classified AMP, the middle trailer car AMT and the driving motor car without pantograph AMA.[2] The trains are operated by Auckland One Rail for Auckland Transport under the AT Metro brand.
