The Hyundai Rotem EMU (also known as R-Train or 1141B) (Chinese: 港鐵東鐵綫現代列車) is a current model of heavy rail electric multiple units used on the Mass Transit Railway in Hong Kong. The 9-car sets are manufactured by Hyundai Rotem for the North South Corridor, an extension of the East Rail line, at a cost of HK$4 billion. and the first delivery took place in 2015, while a further 6 trains were ordered in May 2020, although the 6 trains were never manufactured. Originally scheduled to enter service in late-2017 to early-2018, the trains gradually entered service from 6 February 2021. All train sets were put into service in 2022, replacing the Metro Cammell EMUs and displacing the SP1900 EMUs to the Tuen Ma Line.
