 The railcars were replaced by the "Blue Fern" on Wednesdays for three years until May 1984, to allow the two remaining railcar sets to be serviced while the damaged set was being repaired.In 1989 and again in 1990 the "Blue Fern" train ran instead of railcars after Silver Fern railcar RM1 was involved in an accident.In 2019, the two remaining serviceable Silver Ferns were withdrawn from service by KiwiRail.
