cars on rails in the bush

A couple of post-WW2 British cars as they looked when seen at Mamaku near Rotorua in 1966. This was the last major bush tramway to close in New Zealand in 1974. We assume these cars were used as passenger transport rather than for haulage (which would have been very limited!), and don't know whether they were bought new - our expert on bush trams is out of contact until late January.
