The Metro Cammell EMU (also known as M-Train or Modernisation Train, Chinese: 港鐵現代化列車) is the oldest variation of electric multiple unit that operates on the MTR rapid transit railway system in Hong Kong. A total of 768 cars were built by Metro-Cammell in England (and its successor GEC-Alsthom, later known as Alstom) between 1977 and 1994, and refurbished from 1998 to 2001 by United Goninan.
