The NZR RM classSilver Fern was a class of rail motorin New Zealand. The three air-conditioned and sound-proofed 723-kW 96-seater diesel-electric twin-set railcars were built by Kawasaki under contract with Nissho Iwai of Japan. New Zealand Railways (NZR) classified the railcars as RM (Rail Motor), the same as other railcars, using the Silver Ferns (a national symbol of New Zealand) because of their exterior was made of corrugated stainless steel, like the premier night sleeper train that also ran on the Wellington-Auckland (North Island Main Trunk) route, the Silver Star. The Silver Ferns replaced the three successful Blue Streak railcars on the service.
