The Sydney Trains M sets, also referred to as the Millennium trains, are a class of electric multiple units (EMU) that operate on the Sydney Trains network. Built by EDi Rail between 2002 and 2005, the first sets initially entered service under the CityRail brand on 1 July 2002 after short delays due to electrical defects.[2][3] The M sets were built as "fourth generation" trains for Sydney's suburban rail fleet, replacing the 1960s Tulloch carriages and providing extra capacity on the suburban rail network.[4] The sets currently operate on the T2 Leppington & Inner West, T3 Liverpool & Inner West, T5 Cumberland, T6 Lidcombe & Bankstown, T7 Olympic Park and T8 Airport & South lines.
