NZR RM class (Model T Ford)
The NZR RM class Model T Ford railcar is a type of rail motor that operated on New Zealand's national rail network. Only two were built, classified as RM 4 and RM 5, and they were experimental railcars designed in an attempt to offer improved passenger services on quiet country branch lines that served regions with small populations.
