between Palmerston North and Wellington. On the sale of 50% of Tranz Scenic to directors of the West Coast Railway (subsequently repurchased by Toll) it was transferred to Tranz Scenic (now KiwiRail Scenic), where it remains. The five Metlink lines, from west to east, are:- Rolling stock Metlink's rolling stock consists of electric multiple units and diesel locomotive-hauled carriages. Electric locomotive-hauled trains were withdrawn in 1988 on the retirement of the EW class electric locomotives, displaced by the EM/ET class "Ganz Mavag" units introduced in 1982. DM/D class "English Electric" units have been withdrawn as they became uneconomical to operate. Several DM/D units were kept for peak services and the Johnsonville Line, where the loading gauge and braking capacity prevented the EM/ET units operating. New carriages were introduced to the Capital Connection in 1998 and the Wairarapa Connection in 2007. They are ex-British Rail Mark 2 carriages, re-gauged and refurbished. They replaced NZR 56-foot carriages built between 1937 and 1943. In July 2007, GWRC ordered 48 FP/FT "Matangi" units to increase capacity and replace the remainder of the 70-year-old DM/D units. The Johnsonville Line was upgraded in 2008 and 2009 to accommodate the Matangi units. In 2008, several DM/D units were reintroduced on peak services as an interim measure until the Matangi units arrived. Six SE BR Mark 2 carriages were partially refurbished and introduced for express peak services, top-and-tailed by two refurbished EO class electric locomotives. The locomotives, built in 1968, were used in the Otira Tunnel until its de-electrification in 1997. An additional locomotive was refurbished for backup. Due to mechanical issues and the availability of new rolling stock, the EOs were withdrawn from service in 2011. On 25 June 2012, the last DM/D units were withdrawn from service, just one week shy of 74 years since the first members of the class entered service. The SE carriages formerly used with the EO electric locomotives were fitted with toilets and reallocated to the Wairarapa Connection in July 2013 to ease rolling stock constraints. In June 2013, GWRC decided to purchase 35 additional Matangi units instead of refurbishing the EM/ET units. The last EM/ET units were withdrawn on 27 May 2016 after 34 years in service. KiwiRail provides four diesel-electric locomotives on a "hook-and-tow" basis to operate the Wairarapa Connection trains. Since July 2015, services have been hauled by the DFT class; before then, the DC class was primarily
