Mid 1990's we bought the secondhand diesel railcars ,ADK, ADL type from Perth ( Australia ) to be used in Auckland.
In New Zealand we have been importing some of the Mark 1 ?? railwaycars from the UK. These get completely stripped down and look like new after been refurbished for the Auckland suburban Push Pull trains with dieselelectric locomotives. They have an on board generator 200 kVA which provides 230 / 400 Volts 50 Hz for lighting and auxillaries.
Also the bogies have been replaced to fit the 3 ft 6 gauge used in NZ. These have been put into service over the last few years.
I also recall that old railway cars were imported from Australia to be used for subbie duties in Auckland as above.
VOLTAGES:
Main trunk from Te Rapa to Palmerston North 25,000 V 50 Hz.
Wellington suburban 1500 V dc.
Trams in Wellington and Christchurch 500 V dc.
