The Alstom Movia R151 is the seventh generation electric multiple unit (EMU) rolling stock in operation on the existing North–South (NSL) and East–West (EWL) lines of Singapore's Mass Rapid Transit (MRT) system. It is manufactured by Changchun Alstom Railway Vehicles[a], a joint venture of Alstom[b] and CRRC Changchun under Contract R151 as part of their Movia family of trains.

The new rolling stock is set to progressively replace all of the C151s, C651s and C751Bs, which have been in service for at least 20 years. These new trains are part of the North–South and East–West lines' core systems upgrade and renewal programme. 106 six-car high-capacity trainsets comprising 636 cars were delivered from 21 February 2022 onwards, with the first train entering service on the East–West Line on 4 June 2023.[1]
