Railway electrification in New Zealand Railway electrification in New Zealand Railway electrification was initially adopted by the New Zealand Railways in New Zealand for long tunnels; the Otira Tunnel, the Lyttelton Rail Tunnel and the two Tawa Tunnels of the Tawa Flat Deviation. Electrification of Wellington suburban services started with the Johnsonville Line and Kapiti Line out of Wellington from the 1930s. Auckland suburban services were electrified in 2014–15. Electrification of long distance services on the North Island Main Trunk (NIMT) dates from 1986, although KiwiRail is now considering diesel operation of the NIMT. New long tunnels e.g. the Rimutaka Tunnel and the Kaimai Tunnel
Rimutaka Incline the Rimutaka Incline Railway Heritage Trust was inaugurated with the intention of reinstating the Rimutaka Incline in four stages: Upper Hutt to Summit; Wellington to Upper Hutt (using KiwiRail's Wairarapa Line); Summit to Cross Creek; Cross Creek to Featherston. The base of operations is on land leased from KiwiRail at Maymorn. Largely thanks to the establishment of the Remutaka Rail Trail, most of the original formation has been preserved and is proposed to be incorporated into the reinstated rail operation, with new works required at Maymorn to link the original formation to the station yard and a deviation at Kaitoke
