The SP1900 EMU / SP1950 EMU or IKK Train (formerly KCR EMU SP1900 / SP1950 EMU; 港鐵近畿川崎列車, also known as the Millennium Train during the public promotion) is a model of train that runs on Hong Kong's Tuen Ma line. It was the second model of electric multiple unit rolling stock of the Kowloon-Canton Railway Corporation (KCRC) (after the Metro Cammell EMU, introduced in the 1980s), though they have been operated by MTR Corporation (MTRC) after it merged with KCRC in 2007.
